# CMakeLists.txt
#
# This file enables PCRE2 to be built with the CMake configuration and build
# tool. Download CMake in source or binary form from http://www.cmake.org/
# Converted to support PCRE2 from the original PCRE file, August 2014.
#
# Original listfile by Christian Ehrlicher <Ch.Ehrlicher@gmx.de>
# Refined and expanded by Daniel Richard G. <skunk@iSKUNK.ORG>
# 2007-09-14 mod by Sheri so 7.4 supported configuration options can be entered
# 2007-09-19 Adjusted by PH to retain previous default settings
# 2007-12-26 (a) On UNIX, use names libpcre instead of just pcre
# (b) Ensure pcretest and pcregrep link with the local library,
# not a previously-installed one.
# (c) Add PCRE_SUPPORT_LIBREADLINE, PCRE_SUPPORT_LIBZ, and
# PCRE_SUPPORT_LIBBZ2.
# 2008-01-20 Brought up to date to include several new features by Christian
# Ehrlicher.
# 2008-01-22 Sheri added options for backward compatibility of library names
# when building with minGW:
# if "ON", NON_STANDARD_LIB_PREFIX causes shared libraries to
# be built without "lib" as prefix. (The libraries will be named
# pcre.dll, pcreposix.dll and pcrecpp.dll).
# if "ON", NON_STANDARD_LIB_SUFFIX causes shared libraries to
# be built with suffix of "-0.dll". (The libraries will be named
# libpcre-0.dll, libpcreposix-0.dll and libpcrecpp-0.dll - same names
# built by default with Configure and Make.
# 2008-01-23 PH removed the automatic build of pcredemo.
# 2008-04-22 PH modified READLINE support so it finds NCURSES when needed.
# 2008-07-03 PH updated for revised UCP property support (change of files)
# 2009-03-23 PH applied Steven Van Ingelgem's patch to change the name
# CMAKE_BINARY_DIR to PROJECT_BINARY_DIR so that it works when PCRE
# is included within another project.
# 2009-03-23 PH applied a modified version of Steven Van Ingelgem's patches to
# add options to stop the building of pcregrep and the tests, and
# to disable the final configuration report.
# 2009-04-11 PH applied Christian Ehrlicher's patch to show compiler flags that
# are set by specifying a release type.
# 2010-01-02 PH added test for stdint.h
# 2010-03-02 PH added test for inttypes.h
# 2011-08-01 PH added PCREGREP_BUFSIZE
# 2011-08-22 PH added PCRE_SUPPORT_JIT
# 2011-09-06 PH modified WIN32 ADD_TEST line as suggested by Sergey Cherepanov
# 2011-09-06 PH added PCRE_SUPPORT_PCREGREP_JIT
# 2011-10-04 Sheri added support for including coff data in windows shared libraries
# compiled with MINGW if pcre.rc and/or pcreposix.rc are placed in
# the source dir by the user prior to building
# 2011-10-04 Sheri changed various add_test's to use exes' location built instead
# of DEBUG location only (likely only matters in MSVC)
# 2011-10-04 Sheri added scripts to provide needed variables to RunTest and
# RunGrepTest (used for UNIX and Msys)
# 2011-10-04 Sheri added scripts to provide needed variables and to execute
# RunTest.bat in Win32 (for effortless testing with "make test")
# 2011-10-04 Sheri Increased minimum required cmake version
# 2012-01-06 PH removed pcre_info.c and added pcre_string_utils.c
# 2012-01-10 Zoltan Herczeg added libpcre16 support
# 2012-01-13 Stephen Kelly added out of source build support
# 2012-01-17 PH applied Stephen Kelly's patch to parse the version data out
# of the configure.ac file
# 2012-02-26 PH added support for libedit
# 2012-09-06 PH added support for PCRE_EBCDIC_NL25
# 2012-09-08 ChPe added PCRE32 support
# 2012-10-23 PH added support for VALGRIND and GCOV
# 2012-12-08 PH added patch from Daniel Richard G to quash some MSVC warnings
# 2013-07-01 PH realized that the "support" for GCOV was a total nonsense and
# so it has been removed.
# 2013-10-08 PH got rid of the "source" command, which is a bash-ism (use ".")
# 2013-11-05 PH added support for PARENS_NEST_LIMIT
# 2014-08-29 PH converted the file for PCRE2 (which has no C++).
# 2015-04-24 PH added support for PCRE2_DEBUG
# 2015-07-16 PH updated for new pcre2_find_bracket source module
# 2015-08-24 PH correct C_FLAGS setting (patch from Roy Ivy III)
# 2015-10=16 PH added support for never-backslash-C
# 2016-03-01 PH applied Chris Wilson's patch for MSVC static
# 2016-06-24 PH applied Chris Wilson's second patch, putting the first under
# a new option instead of being unconditional.
# 2016-10-05 PH fixed a typo (PCRE should be PCRE2) in above patch
# fix by David Gaussmann

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

redistributions. The documentation for PCRE2, supplied in the "doc" directory,
is distributed under the same terms as the software itself. The data in the
testdata directory is not copyrighted and is in the public domain.
The basic library functions are written in C and are freestanding. Also
included in the distribution is a set of C++ wrapper functions.
included in the distribution is a just-in-time compiler that can be used to
optimize pattern matching. This is an optional feature that can be omitted when
the library is built.

o Got rid of the C++ wrapper, which included this step:
rm -f *.cc pcrecpparg.h.in pcrecpp.h pcrecpp_internal.h pcre_scanner.h pcre_stringpiece.h.in
o Copied pcre.h.generic to pcre.h and pcre_chartables.c.dist to, you
guessed it, pcre_chartables.c (for Windows). Running ./configure in
UNIX just overwrites them with other ones. Made the rule that makes
pcre_chartables.c copy pcre_chartables.c.dist instead of making a
symbolic link to it. Remove pcre_chartables.c from CLEANFILES.
o Stripped down Makefile.am and configure.ac substantially to remove
libtool dependency (was having trouble on Mac OS X), remove Windows
stuff (Nmap uses a custom MS VC project for this), and insure it only
worries about building libpcre.a (which is now build in the libpcre
directory rather than in libpcre/.libs ). Removed quite a bit of
unneeded things from these files, as well as adding -fno-thread-jumps
when compiling on Mac OS X on Intel (original patch: Kurt Grutzmacher
grutz(a)jingojango.net). [The diff is FAR too large to included here]
o Removed config.sub, config.guess, depcomp, install-sh, and missing.
These files are found in the parent (i.e., Nmap's) directory.
o Comment out some build configuration lines from pcre_internal.h because Nmap
builds a static library:

GENERAL
I (Philip Hazel) have no experience of Windows or VMS sytems and how their
libraries work. The items in the PCRE distribution and Makefile that relate to
anything other than Unix-like systems are untested by me.
There are some other comments and files in the Contrib directory on the ftp
site that you may find useful. See
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
If you want to compile PCRE for a non-Unix system (especially for a system that
does not support "configure" and "make" files), note that the basic PCRE
library consists entirely of code written in Standard C, and so should compile
successfully on any system that has a Standard C compiler and library. The C++
wrapper functions are a separate issue (see below).
The PCRE distribution includes a "configure" file for use by the Configure/Make
build system, as found in many Unix-like environments. There is also support
support for CMake, which some users prefer, in particular in Windows
environments. There are some instructions for CMake under Windows in the
section entitled "Building PCRE with CMake" below. CMake can also be used to
build PCRE in Unix-like systems.
GENERIC INSTRUCTIONS FOR THE PCRE C LIBRARY
The following are generic comments about building the PCRE C library "by hand".
(1) Copy or rename the file config.h.generic as config.h, and edit the macro
settings that it contains to whatever is appropriate for your environment.
In particular, if you want to force a specific value for newline, you can
define the NEWLINE macro. When you compile any of the PCRE modules, you
must specify -DHAVE_CONFIG_H to your compiler so that config.h is included
in the sources.
An alternative approach is not to edit config.h, but to use -D on the
compiler command line to make any changes that you need to the
configuration options. In this case -DHAVE_CONFIG_H must not be set.
NOTE: There have been occasions when the way in which certain parameters
in config.h are used has changed between releases. (In the configure/make
world, this is handled automatically.) When upgrading to a new release,
you are strongly advised to review config.h.generic before re-using what
you had previously.
(2) Copy or rename the file pcre.h.generic as pcre.h.
(3) EITHER:
Copy or rename file pcre_chartables.c.dist as pcre_chartables.c.
OR:
Compile dftables.c as a stand-alone program (using -DHAVE_CONFIG_H if
you have set up config.h), and then run it with the single argument
"pcre_chartables.c". This generates a set of standard character tables
and writes them to that file. The tables are generated using the default
C locale for your system. If you want to use a locale that is specified
by LC_xxx environment variables, add the -L option to the dftables
command. You must use this method if you are building on a system that
uses EBCDIC code.
The tables in pcre_chartables.c are defaults. The caller of PCRE can
specify alternative tables at run time.
(4) Ensure that you have the following header files:
pcre_internal.h
ucp.h
ucpinternal.h
ucptable.h
(5) Also ensure that you have the following file, which is #included as source
when building a debugging version of PCRE, and is also used by pcretest.
pcre_printint.src
(6) Compile the following source files, setting -DHAVE_CONFIG_H as a compiler
option if you have set up config.h with your configuration, or else use
other -D settings to change the configuration as required.
pcre_chartables.c
pcre_compile.c
pcre_config.c
pcre_dfa_exec.c
pcre_exec.c
pcre_fullinfo.c
pcre_get.c
pcre_globals.c
pcre_info.c
pcre_maketables.c
pcre_newline.c
pcre_ord2utf8.c
pcre_refcount.c
pcre_study.c
pcre_tables.c
pcre_try_flipped.c
pcre_ucp_searchfuncs.c
pcre_valid_utf8.c
pcre_version.c
pcre_xclass.c
Make sure that you include -I. in the compiler command (or equivalent for
an unusual compiler) so that all included PCRE header files are first
sought in the current directory. Otherwise you run the risk of picking up
a previously-installed file from somewhere else.
(7) Now link all the compiled code into an object library in whichever form
your system keeps such libraries. This is the basic PCRE C library. If
your system has static and shared libraries, you may have to do this once
for each type.
(8) Similarly, compile pcreposix.c (remembering -DHAVE_CONFIG_H if necessary)
and link the result (on its own) as the pcreposix library.
(9) Compile the test program pcretest.c (again, don't forget -DHAVE_CONFIG_H).
This needs the functions in the pcre and pcreposix libraries when linking.
It also needs the pcre_printint.src source file, which it #includes.
(10) Run pcretest on the testinput files in the testdata directory, and check
that the output matches the corresponding testoutput files. Note that the
supplied files are in Unix format, with just LF characters as line
terminators. You may need to edit them to change this if your system uses
a different convention. If you are using Windows, you probably should use
the wintestinput3 file instead of testinput3 (and the corresponding output
file). This is a locale test; wintestinput3 sets the locale to "french"
rather than "fr_FR", and there some minor output differences.
(11) If you want to use the pcregrep command, compile and link pcregrep.c; it
uses only the basic PCRE library (it does not need the pcreposix library).
THE C++ WRAPPER FUNCTIONS
The PCRE distribution also contains some C++ wrapper functions and tests,
contributed by Google Inc. On a system that can use "configure" and "make",
the functions are automatically built into a library called pcrecpp. It should
be straightforward to compile the .cc files manually on other systems. The
files called xxx_unittest.cc are test programs for each of the corresponding
xxx.cc files.
BUILDING FOR VIRTUAL PASCAL
A script for building PCRE using Borland's C++ compiler for use with VPASCAL
was contributed by Alexander Tokarev. Stefan Weber updated the script and added
additional files. The following files in the distribution are for building PCRE
for use with VP/Borland: makevp_c.txt, makevp_l.txt, makevp.bat, pcregexp.pas.
STACK SIZE IN WINDOWS ENVIRONMENTS
The default processor stack size of 1Mb in some Windows environments is too
small for matching patterns that need much recursion. In particular, test 2 may
fail because of this. Normally, running out of stack causes a crash, but there
have been cases where the test program has just died silently. See your linker
documentation for how to increase stack size if you experience problems. The
Linux default of 8Mb is a reasonable choice for the stack, though even that can
be too small for some pattern/subject combinations.
PCRE has a compile configuration option to disable the use of stack for
recursion so that heap is used instead. However, pattern matching is
significantly slower when this is done. There is more about stack usage in the
"pcrestack" documentation.
LINKING PROGRAMS IN WINDOWS ENVIRONMENTS
If you want to statically link a program against a PCRE library in the form of
a non-dll .a file, you must define PCRE_STATIC before including pcre.h,
otherwise the pcre_malloc() and pcre_free() exported functions will be declared
__declspec(dllimport), with unwanted results.
COMMENTS ABOUT WIN32 BUILDS (see also "BUILDING PCRE WITH CMAKE" below)
There are two ways of building PCRE using the "configure, make, make install"
paradigm on Windows systems: using MinGW or using Cygwin. These are not at all
the same thing; they are completely different from each other. There is also
support for building using CMake, which some users find a more straightforward
way of building PCRE under Windows. However, the tests are not run
automatically when CMake is used.
The MinGW home page (http://www.mingw.org/) says this:
MinGW: A collection of freely available and freely distributable Windows
specific header files and import libraries combined with GNU toolsets that
allow one to produce native Windows programs that do not rely on any
3rd-party C runtime DLLs.
The Cygwin home page (http://www.cygwin.com/) says this:
Cygwin is a Linux-like environment for Windows. It consists of two parts:
. A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
substantial Linux API functionality
. A collection of tools which provide Linux look and feel.
The Cygwin DLL currently works with all recent, commercially released x86 32
bit and 64 bit versions of Windows, with the exception of Windows CE.
On both MinGW and Cygwin, PCRE should build correctly using:
./configure && make && make install
This should create two libraries called libpcre and libpcreposix, and, if you
have enabled building the C++ wrapper, a third one called libpcrecpp. These are
independent libraries: when you like with libpcreposix or libpcrecpp you must
also link with libpcre, which contains the basic functions. (Some earlier
releases of PCRE included the basic libpcre functions in libpcreposix. This no
longer happens.)
A user submitted a special-purpose patch that makes it easy to create
"pcre.dll" under mingw32 using the "msys" environment. It provides "pcre.dll"
as a special target. If you use this target, no other files are built, and in
particular, the pcretest and pcregrep programs are not built. An example of how
this might be used is:
./configure --enable-utf --disable-cpp CFLAGS="-03 -s"; make pcre.dll
Using Cygwin's compiler generates libraries and executables that depend on
cygwin1.dll. If a library that is generated this way is distributed,
cygwin1.dll has to be distributed as well. Since cygwin1.dll is under the GPL
licence, this forces not only PCRE to be under the GPL, but also the entire
application. A distributor who wants to keep their own code proprietary must
purchase an appropriate Cygwin licence.
MinGW has no such restrictions. The MinGW compiler generates a library or
executable that can run standalone on Windows without any third party dll or
licensing issues.
But there is more complication:
If a Cygwin user uses the -mno-cygwin Cygwin gcc flag, what that really does is
to tell Cygwin's gcc to use the MinGW gcc. Cygwin's gcc is only acting as a
front end to MinGW's gcc (if you install Cygwin's gcc, you get both Cygwin's
gcc and MinGW's gcc). So, a user can:
. Build native binaries by using MinGW or by getting Cygwin and using
-mno-cygwin.
. Build binaries that depend on cygwin1.dll by using Cygwin with the normal
compiler flags.
The test files that are supplied with PCRE are in Unix format, with LF
characters as line terminators. It may be necessary to change the line
terminators in order to get some of the tests to work. We hope to improve
things in this area in future.
BUILDING PCRE ON WINDOWS WITH CMAKE
CMake is an alternative build facility that can be used instead of the
traditional Unix "configure". CMake version 2.4.7 supports Borland makefiles,
MinGW makefiles, MSYS makefiles, NMake makefiles, UNIX makefiles, Visual Studio
6, Visual Studio 7, Visual Studio 8, and Watcom W8. The following instructions
were contributed by a PCRE user.
1. Download CMake 2.4.7 or above from http://www.cmake.org/, install and ensure
that cmake\bin is on your path.
2. Unzip (retaining folder structure) the PCRE source tree into a source
directory such as C:\pcre.
3. Create a new, empty build directory: C:\pcre\build\
4. Run CMakeSetup from the Shell envirornment of your build tool, e.g., Msys
for Msys/MinGW or Visual Studio Command Prompt for VC/VC++
5. Enter C:\pcre\pcre-xx and C:\pcre\build for the source and build
directories, respectively
6. Hit the "Configure" button.
7. Select the particular IDE / build tool that you are using (Visual Studio,
MSYS makefiles, MinGW makefiles, etc.)
8. The GUI will then list several configuration options. This is where you can
enable UTF-8 support, etc.
9. Hit "Configure" again. The adjacent "OK" button should now be active.
10. Hit "OK".
11. The build directory should now contain a usable build system, be it a
solution file for Visual Studio, makefiles for MinGW, etc.
USE OF RELATIVE PATHS WITH CMAKE ON WINDOWS
A PCRE user comments as follows:
I thought that others may want to know the current state of
CMAKE_USE_RELATIVE_PATHS support on Windows.
Here it is:
-- AdditionalIncludeDirectories is only partially modified (only the
first path - see below)
-- Only some of the contained file paths are modified - shown below for
pcre.vcproj
-- It properly modifies
I am sure CMake people can fix that if they want to. Until then one will
need to replace existing absolute paths in project files with relative
paths manually (e.g. from VS) - relative to project file location. I did
just that before being told to try CMAKE_USE_RELATIVE_PATHS. Not a big
deal.
AdditionalIncludeDirectories="E:\builds\pcre\build;E:\builds\pcre\pcre-7.5;"
AdditionalIncludeDirectories=".;E:\builds\pcre\pcre-7.5;"
RelativePath="pcre.h">
RelativePath="pcre_chartables.c">
RelativePath="pcre_chartables.c.rule">
TESTING WITH RUNTEST.BAT
1. Copy RunTest.bat into the directory where pcretest.exe has been created.
2. Edit RunTest.bat and insert a line that indentifies the relative location of
the pcre source, e.g.:
set srcdir=..\pcre-7.4-RC3
3. Run RunTest.bat from a command shell environment. Test outputs will
automatically be compared to expected results, and discrepancies will
identified in the console output.
4. To test pcrecpp, run pcrecpp_unittest.exe, pcre_stringpiece_unittest.exe and
pcre_scanner_unittest.exe.
BUILDING UNDER WINDOWS WITH BCC5.5
Michael Roy sent these comments about building PCRE under Windows with BCC5.5:
Some of the core BCC libraries have a version of PCRE from 1998 built in,
which can lead to pcre_exec() giving an erroneous PCRE_ERROR_NULL from a
version mismatch. I'm including an easy workaround below, if you'd like to
include it in the non-unix instructions:
When linking a project with BCC5.5, pcre.lib must be included before any of
the libraries cw32.lib, cw32i.lib, cw32mt.lib, and cw32mti.lib on the command
line.
BUILDING PCRE ON OPENVMS
Dan Mooney sent the following comments about building PCRE on OpenVMS. They
relate to an older version of PCRE that used fewer source files, so the exact
commands will need changing. See the current list of source files above.
"It was quite easy to compile and link the library. I don't have a formal
make file but the attached file [reproduced below] contains the OpenVMS DCL
commands I used to build the library. I had to add #define
POSIX_MALLOC_THRESHOLD 10 to pcre.h since it was not defined anywhere.
The library was built on:
O/S: HP OpenVMS v7.3-1
Compiler: Compaq C v6.5-001-48BCD
Linker: vA13-01
The test results did not match 100% due to the issues you mention in your
documentation regarding isprint(), iscntrl(), isgraph() and ispunct(). I
modified some of the character tables temporarily and was able to get the
results to match. Tests using the fr locale did not match since I don't have
that locale loaded. The study size was always reported to be 3 less than the
value in the standard test output files."

The PCRE APIs
-------------
PCRE is written in C, and it has its own API. The distribution also includes a
set of C++ wrapper functions (see the pcrecpp man page for details), courtesy
of Google Inc.
In addition, there is a set of C wrapper functions that are based on the POSIX
regular expression API (see the pcreposix man page). These end up in the
library called libpcreposix. Note that this just provides a POSIX calling
interface to PCRE; the regular expressions themselves still follow Perl syntax
and semantics. The POSIX API is restricted, and does not give full access to
all of PCRE's facilities.
The header file for the POSIX-style functions is called pcreposix.h. The
official POSIX name is regex.h, but I did not want to risk possible problems
with existing files of that name by distributing it that way. To use PCRE with
an existing program that uses the POSIX API, pcreposix.h will have to be
renamed or pointed at by a link.
If you are using the POSIX interface to PCRE and there is already a POSIX regex
library installed on your system, as well as worrying about the regex.h header
file (as mentioned above), you must also take care when linking programs to
ensure that they link with PCRE's libpcreposix library. Otherwise they may pick
up the POSIX functions of the same name from the other library.
One way of avoiding this confusion is to compile PCRE with the addition of
-Dregcomp=PCREregcomp (and similarly for the other POSIX functions) to the
compiler flags (CFLAGS if you are using "configure" -- see below). This has the
effect of renaming the functions so that the names no longer clash. Of course,
you have to do the same thing for your applications, or write them using the
new names.
Documentation for PCRE
----------------------
If you install PCRE in the normal way on a Unix-like system, you will end up
with a set of man pages whose names all start with "pcre". The one that is just
called "pcre" lists all the others. In addition to these man pages, the PCRE
documentation is supplied in two other forms:
1. There are files called doc/pcre.txt, doc/pcregrep.txt, and
doc/pcretest.txt in the source distribution. The first of these is a
concatenation of the text forms of all the section 3 man pages except
those that summarize individual functions. The other two are the text
forms of the section 1 man pages for the pcregrep and pcretest commands.
These text forms are provided for ease of scanning with text editors or
similar tools. They are installed in <prefix>/share/doc/pcre, where
<prefix> is the installation prefix (defaulting to /usr/local).
2. A set of files containing all the documentation in HTML form, hyperlinked
in various ways, and rooted in a file called index.html, is distributed in
doc/html and installed in <prefix>/share/doc/pcre/html.
Contributions by users of PCRE
------------------------------
You can find contributions from PCRE users in the directory
ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/Contrib
There is a README file giving brief descriptions of what they are. Some are
complete in themselves; others are pointers to URLs containing relevant files.
Some of this material is likely to be well out-of-date. Several of the earlier
contributions provided support for compiling PCRE on various flavours of
Windows (I myself do not use Windows). Nowadays there is more Windows support
in the standard distribution, so these contibutions have been archived.
Building PCRE on non-Unix systems
---------------------------------
For a non-Unix system, please read the comments in the file NON-UNIX-USE,
though if your system supports the use of "configure" and "make" you may be
able to build PCRE in the same way as for Unix-like systems. PCRE can also be
configured in many platform environments using the GUI facility of CMake's
CMakeSetup. It creates Makefiles, solution files, etc.
PCRE has been compiled on many different operating systems. It should be
straightforward to build PCRE on any system that has a Standard C compiler and
library, because it uses only Standard C functions.
Building PCRE on Unix-like systems
----------------------------------
If you are using HP's ANSI C++ compiler (aCC), please see the special note
in the section entitled "Using HP's ANSI C++ compiler (aCC)" below.
The following instructions assume the use of the widely used "configure, make,
make install" process. There is also support for CMake in the PCRE
distribution; there are some comments about using CMake in the NON-UNIX-USE
file, though it can also be used in Unix-like systems.
To build PCRE on a Unix-like system, first run the "configure" command from the
PCRE distribution directory, with your current directory set to the directory
where you want the files to be created. This command is a standard GNU
"autoconf" configuration script, for which generic instructions are supplied in
the file INSTALL.
Most commonly, people build PCRE within its own distribution directory, and in
this case, on many systems, just running "./configure" is sufficient. However,
the usual methods of changing standard defaults are available. For example:
CFLAGS='-O2 -Wall' ./configure --prefix=/opt/local
specifies that the C compiler should be run with the flags '-O2 -Wall' instead
of the default, and that "make install" should install PCRE under /opt/local
instead of the default /usr/local.
If you want to build in a different directory, just run "configure" with that
directory as current. For example, suppose you have unpacked the PCRE source
into /source/pcre/pcre-xxx, but you want to build it in /build/pcre/pcre-xxx:
cd /build/pcre/pcre-xxx
/source/pcre/pcre-xxx/configure
PCRE is written in C and is normally compiled as a C library. However, it is
possible to build it as a C++ library, though the provided building apparatus
does not have any features to support this.
There are some optional features that can be included or omitted from the PCRE
library. You can read more about them in the pcrebuild man page.
. If you want to suppress the building of the C++ wrapper library, you can add
--disable-cpp to the "configure" command. Otherwise, when "configure" is run,
it will try to find a C++ compiler and C++ header files, and if it succeeds,
it will try to build the C++ wrapper.
. If you want to make use of the support for UTF-8 character strings in PCRE,
you must add --enable-utf8 to the "configure" command. Without it, the code
for handling UTF-8 is not included in the library. (Even when included, it
still has to be enabled by an option at run time.)
. If, in addition to support for UTF-8 character strings, you want to include
support for the \P, \p, and \X sequences that recognize Unicode character
properties, you must add --enable-unicode-properties to the "configure"
command. This adds about 30K to the size of the library (in the form of a
property table); only the basic two-letter properties such as Lu are
supported.
. You can build PCRE to recognize either CR or LF or the sequence CRLF or any
of the preceding, or any of the Unicode newline sequences as indicating the
end of a line. Whatever you specify at build time is the default; the caller
of PCRE can change the selection at run time. The default newline indicator
is a single LF character (the Unix standard). You can specify the default
newline indicator by adding --enable-newline-is-cr or --enable-newline-is-lf
or --enable-newline-is-crlf or --enable-newline-is-anycrlf or
--enable-newline-is-any to the "configure" command, respectively.
If you specify --enable-newline-is-cr or --enable-newline-is-crlf, some of
the standard tests will fail, because the lines in the test files end with
LF. Even if the files are edited to change the line endings, there are likely
to be some failures. With --enable-newline-is-anycrlf or
--enable-newline-is-any, many tests should succeed, but there may be some
failures.
. By default, the sequence \R in a pattern matches any Unicode line ending
sequence. This is independent of the option specifying what PCRE considers to
be the end of a line (see above). However, the caller of PCRE can restrict \R
to match only CR, LF, or CRLF. You can make this the default by adding
--enable-bsr-anycrlf to the "configure" command (bsr = "backslash R").
. When called via the POSIX interface, PCRE uses malloc() to get additional
storage for processing capturing parentheses if there are more than 10 of
them in a pattern. You can increase this threshold by setting, for example,
--with-posix-malloc-threshold=20
on the "configure" command.
. PCRE has a counter that can be set to limit the amount of resources it uses.
If the limit is exceeded during a match, the match fails. The default is ten
million. You can change the default by setting, for example,
--with-match-limit=500000
on the "configure" command. This is just the default; individual calls to
pcre_exec() can supply their own value. There is more discussion on the
pcreapi man page.
. There is a separate counter that limits the depth of recursive function calls
during a matching process. This also has a default of ten million, which is
essentially "unlimited". You can change the default by setting, for example,
--with-match-limit-recursion=500000
Recursive function calls use up the runtime stack; running out of stack can
cause programs to crash in strange ways. There is a discussion about stack
sizes in the pcrestack man page.
. The default maximum compiled pattern size is around 64K. You can increase
this by adding --with-link-size=3 to the "configure" command. You can
increase it even more by setting --with-link-size=4, but this is unlikely
ever to be necessary. Increasing the internal link size will reduce
performance.
. You can build PCRE so that its internal match() function that is called from
pcre_exec() does not call itself recursively. Instead, it uses memory blocks
obtained from the heap via the special functions pcre_stack_malloc() and
pcre_stack_free() to save data that would otherwise be saved on the stack. To
build PCRE like this, use
--disable-stack-for-recursion
on the "configure" command. PCRE runs more slowly in this mode, but it may be
necessary in environments with limited stack sizes. This applies only to the
pcre_exec() function; it does not apply to pcre_dfa_exec(), which does not
use deeply nested recursion. There is a discussion about stack sizes in the
pcrestack man page.
. For speed, PCRE uses four tables for manipulating and identifying characters
whose code point values are less than 256. By default, it uses a set of
tables for ASCII encoding that is part of the distribution. If you specify
--enable-rebuild-chartables
a program called dftables is compiled and run in the default C locale when
you obey "make". It builds a source file called pcre_chartables.c. If you do
not specify this option, pcre_chartables.c is created as a copy of
pcre_chartables.c.dist. See "Character tables" below for further information.
. It is possible to compile PCRE for use on systems that use EBCDIC as their
default character code (as opposed to ASCII) by specifying
--enable-ebcdic
This automatically implies --enable-rebuild-chartables (see above).
. It is possible to compile pcregrep to use libz and/or libbz2, in order to
read .gz and .bz2 files (respectively), by specifying one or both of
--enable-pcregrep-libz
--enable-pcregrep-libbz2
Of course, the relevant libraries must be installed on your system.
. It is possible to compile pcretest so that it links with the libreadline
library, by specifying
--enable-pcretest-libreadline
If this is done, when pcretest's input is from a terminal, it reads it using
the readline() function. This provides line-editing and history facilities.
Note that libreadline is GPL-licenced, so if you distribute a binary of
pcretest linked in this way, there may be licensing issues.
The "configure" script builds the following files for the basic C library:
. Makefile is the makefile that builds the library
. config.h contains build-time configuration options for the library
. pcre.h is the public PCRE header file
. pcre-config is a script that shows the settings of "configure" options
. libpcre.pc is data for the pkg-config command
. libtool is a script that builds shared and/or static libraries
. RunTest is a script for running tests on the basic C library
. RunGrepTest is a script for running tests on the pcregrep command
Versions of config.h and pcre.h are distributed in the PCRE tarballs under
the names config.h.generic and pcre.h.generic. These are provided for the
benefit of those who have to built PCRE without the benefit of "configure". If
you use "configure", the .generic versions are not used.
If a C++ compiler is found, the following files are also built:
. libpcrecpp.pc is data for the pkg-config command
. pcrecpparg.h is a header file for programs that call PCRE via the C++ wrapper
. pcre_stringpiece.h is the header for the C++ "stringpiece" functions
The "configure" script also creates config.status, which is an executable
script that can be run to recreate the configuration, and config.log, which
contains compiler output from tests that "configure" runs.
Once "configure" has run, you can run "make". It builds two libraries, called
libpcre and libpcreposix, a test program called pcretest, and the pcregrep
command. If a C++ compiler was found on your system, "make" also builds the C++
wrapper library, which is called libpcrecpp, and some test programs called
pcrecpp_unittest, pcre_scanner_unittest, and pcre_stringpiece_unittest.
Building the C++ wrapper can be disabled by adding --disable-cpp to the
"configure" command.
The command "make check" runs all the appropriate tests. Details of the PCRE
tests are given below in a separate section of this document.
You can use "make install" to install PCRE into live directories on your
system. The following are installed (file names are all relative to the
<prefix> that is set when "configure" is run):
Commands (bin):
pcretest
pcregrep

If you want to remove PCRE from your system, you can run "make uninstall".
This removes all the files that "make install" installed. However, it does not
remove any directories, because these are often shared with other programs.
Retrieving configuration information on Unix-like systems
---------------------------------------------------------
Running "make install" installs the command pcre-config, which can be used to
recall information about the PCRE configuration and installation. For example:
pcre-config --version
prints the version number, and
pcre-config --libs
outputs information about where the library is installed. This command can be
included in makefiles for programs that use PCRE, saving the programmer from
having to remember too many details.
The pkg-config command is another system for saving and retrieving information
about installed libraries. Instead of separate commands for each library, a
single command is used. For example:
pkg-config --cflags pcre
The data is held in *.pc files that are installed in a directory called
<prefix>/lib/pkgconfig.
Shared libraries on Unix-like systems
-------------------------------------
The default distribution builds PCRE as shared libraries and static libraries,
as long as the operating system supports shared libraries. Shared library
support relies on the "libtool" script which is built as part of the
"configure" process.
The libtool script is used to compile and link both shared and static
libraries. They are placed in a subdirectory called .libs when they are newly
built. The programs pcretest and pcregrep are built to use these uninstalled
libraries (by means of wrapper scripts in the case of shared libraries). When
you use "make install" to install shared libraries, pcregrep and pcretest are
automatically re-built to use the newly installed shared libraries before being
installed themselves. However, the versions left in the build directory still
use the uninstalled libraries.
To build PCRE using static libraries only you must use --disable-shared when
configuring it. For example:
./configure --prefix=/usr/gnu --disable-shared
Then run "make" in the usual way. Similarly, you can use --disable-static to
build only shared libraries.
Cross-compiling on Unix-like systems
------------------------------------
You can specify CC and CFLAGS in the normal way to the "configure" command, in
order to cross-compile PCRE for some other host. However, you should NOT
specify --enable-rebuild-chartables, because if you do, the dftables.c source
file is compiled and run on the local host, in order to generate the inbuilt
character tables (the pcre_chartables.c file). This will probably not work,
because dftables.c needs to be compiled with the local compiler, not the cross
compiler.
When --enable-rebuild-chartables is not specified, pcre_chartables.c is created
by making a copy of pcre_chartables.c.dist, which is a default set of tables
that assumes ASCII code. Cross-compiling with the default tables should not be
a problem.
If you need to modify the character tables when cross-compiling, you should
move pcre_chartables.c.dist out of the way, then compile dftables.c by hand and
run it on the local host to make a new version of pcre_chartables.c.dist.
Then when you cross-compile PCRE this new version of the tables will be used.
Using HP's ANSI C++ compiler (aCC)
----------------------------------
Unless C++ support is disabled by specifying the "--disable-cpp" option of the
"configure" script, you must include the "-AA" option in the CXXFLAGS
environment variable in order for the C++ components to compile correctly.
Also, note that the aCC compiler on PA-RISC platforms may have a defect whereby
needed libraries fail to get included when specifying the "-AA" compiler
option. If you experience unresolved symbols when linking the C++ programs,
use the workaround of specifying the following environment variable prior to
running the "configure" script:
CXXLDFLAGS="-lstd_v2 -lCsup_v2"
Making new tarballs
-------------------
The command "make dist" creates three PCRE tarballs, in tar.gz, tar.bz2, and
zip formats. The command "make distcheck" does the same, but then does a trial
build of the new distribution to ensure that it works.
If you have modified any of the man page sources in the doc directory, you
should first run the PrepareRelease script before making a distribution. This
script creates the .txt and HTML forms of the documentation from the man pages.
Testing PCRE
------------
To test the basic PCRE library on a Unix system, run the RunTest script that is
created by the configuring process. There is also a script called RunGrepTest
that tests the options of the pcregrep command. If the C++ wrapper library is
built, three test programs called pcrecpp_unittest, pcre_scanner_unittest, and
pcre_stringpiece_unittest are also built.
Both the scripts and all the program tests are run if you obey "make check" or
"make test". For other systems, see the instructions in NON-UNIX-USE.
The RunTest script runs the pcretest test program (which is documented in its
own man page) on each of the testinput files in the testdata directory in
turn, and compares the output with the contents of the corresponding testoutput
files. A file called testtry is used to hold the main output from pcretest
(testsavedregex is also used as a working file). To run pcretest on just one of
the test files, give its number as an argument to RunTest, for example:
RunTest 2
The first test file can also be fed directly into the perltest.pl script to
check that Perl gives the same results. The only difference you should see is
in the first few lines, where the Perl version is given instead of the PCRE
version.
The second set of tests check pcre_fullinfo(), pcre_info(), pcre_study(),
pcre_copy_substring(), pcre_get_substring(), pcre_get_substring_list(), error
detection, and run-time flags that are specific to PCRE, as well as the POSIX
wrapper API. It also uses the debugging flags to check some of the internals of
pcre_compile().
If you build PCRE with a locale setting that is not the standard C locale, the
character tables may be different (see next paragraph). In some cases, this may
cause failures in the second set of tests. For example, in a locale where the
isprint() function yields TRUE for characters in the range 128-255, the use of
[:isascii:] inside a character class defines a different set of characters, and
this shows up in this test as a difference in the compiled code, which is being
listed for checking. Where the comparison test output contains [\x00-\x7f] the
test will contain [\x00-\xff], and similarly in some other cases. This is not a
bug in PCRE.
The third set of tests checks pcre_maketables(), the facility for building a
set of character tables for a specific locale and using them instead of the
default tables. The tests make use of the "fr_FR" (French) locale. Before
running the test, the script checks for the presence of this locale by running
the "locale" command. If that command fails, or if it doesn't include "fr_FR"
in the list of available locales, the third test cannot be run, and a comment
is output to say why. If running this test produces instances of the error
** Failed to set locale "fr_FR"
in the comparison output, it means that locale is not available on your system,
despite being listed by "locale". This does not mean that PCRE is broken.
[If you are trying to run this test on Windows, you may be able to get it to
work by changing "fr_FR" to "french" everywhere it occurs. Alternatively, use
RunTest.bat. The version of RunTest.bat included with PCRE 7.4 and above uses
Windows versions of test 2. More info on using RunTest.bat is included in the
document entitled NON-UNIX-USE.]
The fourth test checks the UTF-8 support. It is not run automatically unless
PCRE is built with UTF-8 support. To do this you must set --enable-utf8 when
running "configure". This file can be also fed directly to the perltest script,
provided you are running Perl 5.8 or higher. (For Perl 5.6, a small patch,
commented in the script, can be be used.)
The fifth test checks error handling with UTF-8 encoding, and internal UTF-8
features of PCRE that are not relevant to Perl.
The sixth test checks the support for Unicode character properties. It it not
run automatically unless PCRE is built with Unicode property support. To to
this you must set --enable-unicode-properties when running "configure".
The seventh, eighth, and ninth tests check the pcre_dfa_exec() alternative
matching function, in non-UTF-8 mode, UTF-8 mode, and UTF-8 mode with Unicode
property support, respectively. The eighth and ninth tests are not run
automatically unless PCRE is build with the relevant support.
Character tables
----------------
For speed, PCRE uses four tables for manipulating and identifying characters
whose code point values are less than 256. The final argument of the
pcre_compile() function is a pointer to a block of memory containing the
concatenated tables. A call to pcre_maketables() can be used to generate a set
of tables in the current locale. If the final argument for pcre_compile() is
passed as NULL, a set of default tables that is built into the binary is used.
The source file called pcre_chartables.c contains the default set of tables. By
default, this is created as a copy of pcre_chartables.c.dist, which contains
tables for ASCII coding. However, if --enable-rebuild-chartables is specified
for ./configure, a different version of pcre_chartables.c is built by the
program dftables (compiled from dftables.c), which uses the ANSI C character
handling functions such as isalnum(), isalpha(), isupper(), islower(), etc. to
build the table sources. This means that the default C locale which is set for
your system will control the contents of these default tables. You can change
the default tables by editing pcre_chartables.c and then re-building PCRE. If
you do this, you should take care to ensure that the file does not get
automatically re-generated. The best way to do this is to move
pcre_chartables.c.dist out of the way and replace it with your customized
tables.
When the dftables program is run as a result of --enable-rebuild-chartables,
it uses the default C locale that is set on your system. It does not pay
attention to the LC_xxx environment variables. In other words, it uses the
system's default locale rather than whatever the compiling user happens to have
set. If you really do want to build a source set of character tables in a
locale that is specified by the LC_xxx variables, you can run the dftables
program by hand with the -L option. For example:
./dftables -L pcre_chartables.c.special
The first two 256-byte tables provide lower casing and case flipping functions,
respectively. The next table consists of three 32-byte bit maps which identify
digits, "word" characters, and white space, respectively. These are used when
building 32-byte bit maps that represent character classes for code points less
than 256.
The final 256-byte table has bits indicating various character types, as
follows:
1 white space character
2 letter
4 decimal digit
8 hexadecimal digit
16 alphanumeric or '_'
128 regular expression metacharacter or binary zero
You should not alter the set of characters that contain the 128 bit, as that
will cause PCRE to malfunction.

# FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME (DEFAULT_MSG|"Custom failure message") VAR1 ... )
# This macro is intended to be used in FindXXX.cmake modules files.
# It handles the REQUIRED and QUIET argument to FIND_PACKAGE() and
# it also sets the <UPPERCASED_NAME>_FOUND variable.
# The package is found if all variables listed are TRUE.
# Example:
#
# FIND_PACKAGE_HANDLE_STANDARD_ARGS(LibXml2 DEFAULT_MSG LIBXML2_LIBRARIES LIBXML2_INCLUDE_DIR)
#
# LibXml2 is considered to be found, if both LIBXML2_LIBRARIES and
# LIBXML2_INCLUDE_DIR are valid. Then also LIBXML2_FOUND is set to TRUE.
# If it is not found and REQUIRED was used, it fails with FATAL_ERROR,
# independent whether QUIET was used or not.
# If it is found, the location is reported using the VAR1 argument, so
# here a message "Found LibXml2: /usr/lib/libxml2.so" will be printed out.
# If the second argument is DEFAULT_MSG, the message in the failure case will
# be "Could NOT find LibXml2", if you don't like this message you can specify

/* On Unix-like systems config.h.in is converted by "configure" into config.h.
Some other environments also support the use of "configure". PCRE is written in
Standard C, but there are a few non-standard things it can cope with, allowing
it to run on SunOS4 and other "close to standard" systems.
If you are going to build PCRE "by hand" on a system without "configure" you
should copy the distributed config.h.generic to config.h, and then set up the
macro definitions the way you need them. You must then add -DHAVE_CONFIG_H to
all of your compile commands, so that config.h is included at the start of
every source.
Alternatively, you can avoid editing by using -D on the compiler command line
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H.
PCRE uses memmove() if HAVE_MEMMOVE is set to 1; otherwise it uses bcopy() if
HAVE_BCOPY is set to 1. If your system has neither bcopy() nor memmove(), set

## Note that this doesn't just cater to obsosete pre-3.x GCC compilers.

## (see the conditional assignment to $gccflag above).
## There are various ways to get dependency output from gcc. Here's
## why we pick this rather obscure method:
## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

In the 1st form, copy SRCFILE to DSTFILE.
In the 2nd and 3rd, copy all SRCFILES to DIRECTORY.
In the 4th, create DIRECTORIES.
Options:
--help display this help and exit.
--version display version info and exit.
-c (ignored)
-C install only if different (preserve data modification time)
-d create directories instead of installing files.
-g GROUP $chgrpprog installed files to GROUP.
-m MODE $chmodprog installed files to MODE.
-o USER $chownprog installed files to USER.
-p pass -p to $cpprog.
-s $stripprog installed files.
-S SUFFIX attempt to back up existing files, with suffix SUFFIX.
-t DIRECTORY install into DIRECTORY.
-T report an error if DSTFILE is a directory.
Environment variables override the default commands:
CHGRPPROG CHMODPROG CHOWNPROG CMPPROG CPPROG MKDIRPROG MVPROG
RMPROG STRIPPROG
By default, rm is invoked with -f; when overridden with RMPROG,
it's up to you to specify -f if you want it.
If -S is not specified, no backups are attempted.

# SYNOPSIS
#
# AX_PTHREAD([ACTION-IF-FOUND[, ACTION-IF-NOT-FOUND]])
#
# DESCRIPTION
#
# This macro figures out how to build C programs using POSIX threads. It
# sets the PTHREAD_LIBS output variable to the threads library and linker
# flags, and the PTHREAD_CFLAGS output variable to any special C compiler
# flags that are needed. (The user can also force certain compiler
# flags/libs to be tested by setting these environment variables.)
#
# Also sets PTHREAD_CC to any special C compiler that is needed for
# multi-threaded programs (defaults to the value of CC otherwise). (This
# is necessary on AIX to use the special cc_r compiler alias.)
#
# NOTE: You are assumed to not only compile your program with these flags,
# but also link it with them as well. e.g. you should link with
# $PTHREAD_CC $CFLAGS $PTHREAD_CFLAGS $LDFLAGS ... $PTHREAD_LIBS $LIBS
#
# If you are only building threads programs, you may wish to use these
# variables in your default LIBS, CFLAGS, and CC:
#
# LIBS="$PTHREAD_LIBS $LIBS"
# CFLAGS="$CFLAGS $PTHREAD_CFLAGS"
# CC="$PTHREAD_CC"
#
# In addition, if the PTHREAD_CREATE_JOINABLE thread-attribute constant
# has a nonstandard name, defines PTHREAD_CREATE_JOINABLE to that name
# (e.g. PTHREAD_CREATE_UNDETACHED on AIX).
#
# Also HAVE_PTHREAD_PRIO_INHERIT is defined if pthread is found and the
# PTHREAD_PRIO_INHERIT symbol is defined when compiling with
# PTHREAD_CFLAGS.
#
# ACTION-IF-FOUND is a list of shell commands to run if a threads library
# is found, and ACTION-IF-NOT-FOUND is a list of commands to run it if it
# is not found. If ACTION-IF-FOUND is not specified, the default action
# will define HAVE_PTHREAD.
#
# Please let the authors know if this macro fails on any platform, or if
# you have any other suggestions or comments. This macro was based on work
# by SGJ on autoconf scripts for FFTW (http://www.fftw.org/) (with help
# from M. Frigo), as well as ac_pthread and hb_pthread macros posted by
# Alejandro Forero Cuervo to the autoconf macro repository. We are also
# grateful for the helpful feedback of numerous users.

# lthread: LinuxThreads port on FreeBSD (also preferred to -pthread)
# -pthread: Linux/gcc (kernel threads), BSD/gcc (userland threads)
# -pthreads: Solaris/gcc
# -mthreads: Mingw32/gcc, Lynx/gcc
# -mt: Sun Workshop C (may only link SunOS threads [-lthread], but it
# doesn't hurt to check since this sometimes defines pthreads too;
# also defines -D_REENTRANT)

# These exist entirely to fool aclocal when bootstrapping libtool.
#
# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN),
# which have later been changed to m4_define as they aren't part of the
# exported API, or moved to Autoconf or Automake where they belong.
#
# The trouble is, aclocal is a bit thick. It'll see the old AC_DEFUN
# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
# using a macro with the same name in our local m4/libtool.m4 it'll
# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
# and doesn't know about Autoconf macros at all.)
#
# So we provide this file, which has a silly filename so it's always
# included after everything else. This provides aclocal with the
# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
# because those macros already exist, or will be overwritten later.
# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6.
#
# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
# Yes, that means every name once taken will need to remain here until
# we give up compatibility with versions before 1.7, at which point
# we need to keep only those names which we still refer to.
# This is to help aclocal find these macros, as it can't see m4_define.

/* This file contains character tables that are used when no external tables
are passed to PCRE by the application that calls it. The tables are used only
for characters whose code values are less than 256.
This is a default version of the tables that assumes ASCII encoding. A program
called dftables (which is distributed with PCRE) can be used to build
alternative versions of this file. This is necessary if you are running in an
EBCDIC environment, or if you want to default to a different encoding, for
example ISO-8859-1. When dftables is run, it creates these tables in the
current locale. If PCRE is configured with --enable-rebuild-chartables, this
happens automatically.
The following #includes are present because without the gcc 4.x may remove the
array definition from the final binary if PCRE is built into a static library
and dead code stripping is activated. This leads to link errors. Pulling in the
header ensures that the array gets flagged as "someone outside this compilation
unit might reference this" and so it will always be supplied to the linker. */

the canonical format. Once somebody had pointed out RFC 3629 to me (it
obsoletes 2279), additional restrictions were applied. The values are now
limited to be between 0 and 0x0010ffff, no more than 4 bytes long, and the
subrange 0xd000 to 0xdfff is excluded.

turns out the gcc treats this case as a single empty string - which is what we

/* PCRE2 is written in Standard C, but there are a few non-standard things it
can cope with, allowing it to run on SunOS4 and other "close to standard"
systems.
In environments that support the GNU autotools, config.h.in is converted into
config.h by the "configure" script. In environments that use CMake,
config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
hand" without using "configure" or CMake, you should copy the distributed
config.h.generic to config.h, and edit the macro definitions to be the way you
need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
so that config.h is included at the start of every source.
Alternatively, you can avoid editing by using -D on the compiler command line
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
but if you do, default values will be taken from config.h for non-boolean
macros that are not defined on the command line.
Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
such macros are listed as a commented #undef in config.h.generic. Macros such
as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
sure both macros are undefined; an emulation function will then be used. */
/* By default, the \R escape sequence matches any Unicode line ending
character or sequence of characters. If BSR_ANYCRLF is defined (to any
value), this is changed so that backslash-R matches only CR, LF, or CRLF.

/* PCRE2 is written in Standard C, but there are a few non-standard things it
can cope with, allowing it to run on SunOS4 and other "close to standard"
systems.
In environments that support the GNU autotools, config.h.in is converted into
config.h by the "configure" script. In environments that use CMake,
config-cmake.in is converted into config.h. If you are going to build PCRE2 "by
hand" without using "configure" or CMake, you should copy the distributed
config.h.generic to config.h, and edit the macro definitions to be the way you
need them. You must then add -DHAVE_CONFIG_H to all of your compile commands,
so that config.h is included at the start of every source.
Alternatively, you can avoid editing by using -D on the compiler command line
to set the macro values. In this case, you do not have to set -DHAVE_CONFIG_H,
but if you do, default values will be taken from config.h for non-boolean
macros that are not defined on the command line.
Boolean macros such as HAVE_STDLIB_H and SUPPORT_PCRE2_8 should either be
defined (conventionally to 1) for TRUE, and not defined at all for FALSE. All
such macros are listed as a commented #undef in config.h.generic. Macros such
as MATCH_LIMIT, whose actual value is relevant, have defaults defined, but are
surrounded by #ifndef/#endif lines so that the value can be overridden by -D.
PCRE2 uses memmove() if HAVE_MEMMOVE is defined; otherwise it uses bcopy() if
HAVE_BCOPY is defined. If your system has neither bcopy() nor memmove(), make
sure both macros are undefined; an emulation function will then be used. */

character or sequence of characters. If BSR_ANYCRLF is defined (to any

happens automatically.

PCRE2_PRERELEASE is set to an empty string (which it is for real releases).
If the second alternative is used in this case, it does not leave a space
before the date. On the other hand, if all four macros are put into a single
XSTRING when PCRE2_PRERELEASE is not empty, an unwanted space is inserted.
There are problems using an "obvious" approach like this:
XSTRING(PCRE2_MAJOR) "." XSTRING(PCRE_MINOR)
XSTRING(PCRE2_PRERELEASE) " " XSTRING(PCRE_DATE)
because, when PCRE2_PRERELEASE is empty, this leads to an attempted expansion
of STRING(). The C standard states: "If (before argument substitution) any
argument consists of no preprocessing tokens, the behavior is undefined." It
turns out the gcc treats this case as a single empty string - which is what
we really want - but Visual C grumbles about the lack of an argument for the
macro. Unfortunately, both are within their rights. As there seems to be no
way to test for a macro's value being empty at compile time, we have to
resort to a runtime test. */

long string. We cannot use a table of offsets, because the lengths of inserts
such as XSTRING(MAX_NAME_SIZE) are not known. Instead,
pcre2_get_error_message() counts through to the one it wants - this isn't a
performance issue because these strings are used only when there is an error.

counting through. */

/* This module contains mode-dependent macro and structure definitions. The
file is #included by pcre2_internal.h if PCRE2_CODE_UNIT_WIDTH is defined.
These mode-dependent items are kept in a separate file so that they can also be
#included multiple times for different code unit widths by pcre2test in order
to have access to the hidden structures at all supported widths.
Some of the mode-dependent macros are required at different widths for
different parts of the pcre2test code (in particular, the included
pcre_printint.c file). We undefine them here so that they can be re-defined for
multiple inclusions. Not all of these are used in pcre2test, but it's easier
just to undefine them all. */

/* PCRE keeps offsets in its compiled code as at least 16-bit quantities
(always stored in big-endian order in 8-bit mode) by default. These are used,
for example, to link from the start of a subpattern to its alternatives and its
end. The use of 16 bits per offset limits the size of an 8-bit compiled regex
to around 64K, which is big enough for almost everybody. However, I received a
request for an even bigger limit. For this reason, and also to make the code
easier to maintain, the storing and loading of offsets from the compiled code
unit string is now handled by the macros that are defined here.
The macros are controlled by the value of LINK_SIZE. This defaults to 2, but
values of 3 or 4 are also supported. */

PCRE2 is compiled with Unicode support. The function returns TRUE if there is
no Unicode support; however, it should never be called in that circumstance
because an error is given by pcre2_compile() if a script run is called for in a
version of PCRE2 compiled without Unicode support.

/* This table encodes the rules for finding the end of an extended grapheme
cluster. Every code point has a grapheme break property which is one of the
ucp_gbXX values defined in pcre2_ucp.h. These changed between Unicode versions
10 and 11. The 2-dimensional table is indexed by the properties of two adjacent
code points. The left property selects a word from the table, and the right
property selects a bit from that word like this:
PRIV(ucp_gbtable)[left-property] & (1u << right-property)
The value is non-zero if a grapheme break is NOT permitted between the relevant
two code points. The breaking rules are as follows:
1. Break at the start and end of text (pretty obviously).
2. Do not break between a CR and LF; otherwise, break before and after
controls.
3. Do not break Hangul syllable sequences, the rules for which are:
L may be followed by L, V, LV or LVT
LV or V may be followed by V or T
LVT or T may be followed by T
4. Do not break before extending characters or zero-width-joiner (ZWJ).
The following rules are only for extended grapheme clusters (but that's what we
are implementing).
5. Do not break before SpacingMarks.
6. Do not break after Prepend characters.
7. Do not break within emoji modifier sequences or emoji zwj sequences. That
is, do not break between characters with the Extended_Pictographic property.
Extend and ZWJ characters are allowed between the characters; this cannot be
represented in this table, the code has to deal with it.
8. Do not break within emoji flag sequences. That is, do not break between
regional indicator (RI) symbols if there are an odd number of RI characters
before the break point. This table encodes "join RI characters"; the code
has to deal with checking for previous adjoining RIs.
9. Otherwise, break everywhere.
