PCRE LICENCE
------------
PCRE is a library of functions to support regular expressions whose syntax
and semantics are as close as possible to those of the Perl 5 language.
Release 6 of PCRE is distributed under the terms of the "BSD" licence, as
specified below. The documentation for PCRE, supplied in the "doc"
directory, is distributed under the same terms as the software itself.
The basic library functions are written in C and are freestanding. Also
included in the distribution is a set of C++ wrapper functions.

Basic Installation
==================
These are generic installation instructions that apply to systems that
can run the `configure' shell script - Unix systems and any that imitate
it. They are not specific to PCRE. There are PCRE-specific instructions
for non-Unix systems in the file NON-UNIX-USE.
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, a file
`config.cache' that saves the results of its tests to speed up
reconfiguring, and a file `config.log' containing compiler output
(useful mainly for debugging `configure').
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 at some point `config.cache'
contains results you don't want to keep, you may remove or edit it.
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.in' is used to create `configure' by a program
called `autoconf'. You only need `configure.in' if you want to change
it or regenerate `configure' using a newer version of `autoconf'.
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. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.
`./configure' to configure the package for your system.
Running `configure' takes awhile. While running, it prints some
messages telling which features it is checking for.

Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. You can give `configure'
initial values for variables by setting them in the environment. Using
a Bourne-compatible shell, you can do that on the command line like
this:
CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
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.
Or on systems that have the `env' program, you can do it like this:
env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
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
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 must use a version of `make' that
supports the `VPATH' variable, such as GNU `make'. `cd' to the
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 `..'.
If you have to use a `make' that does not supports the `VPATH'
variable, you have 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.
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' will install the package's files in
`/usr/local/bin', `/usr/local/man', etc. You can specify an
installation prefix other than `/usr/local' by giving `configure' the
option `--prefix=PATH'.
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
give `configure' the option `--exec-prefix=PATH', the package will use
PATH as the prefix for installing programs and libraries.

Specifying the System Type
==========================
There may be some features `configure' can not figure out
automatically, but needs to determine by the type of host the package
will run on. Usually `configure' can figure that out, but if it prints
a message saying it can not guess the host type, give it the
`--host=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name with three fields:
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
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 host type.
where SYSTEM can have one of these forms:
If you are building compiler tools for cross-compiling, you can also
use the `--target=TYPE' option to select the type of system they will
produce code for and the `--build=TYPE' option to select the type of
system on which you are compiling the package.
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'.
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.
Operation Controls
Defining Variables
==================
`configure' recognizes the following options to control how it
operates.
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:
`--cache-file=FILE'
Use and save the results of the tests in FILE instead of
`./config.cache'. Set FILE to `/dev/null' to disable caching, for
debugging `configure'.
./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'

traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.

If you want to compile PCRE for a non-Unix system (or perhaps, more strictly,
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).

GENERIC INSTRUCTIONS FOR THE C LIBRARY
GENERIC INSTRUCTIONS FOR THE PCRE C LIBRARY
The following are generic comments about building PCRE. The interspersed
indented commands are suggestions from Mark Tetrode as to which commands you
might use on a Windows system to build a static library.
The following are generic comments about building the PCRE C library "by hand".
(1) Copy or rename the file config.in as config.h, and change the macros that
define HAVE_STRERROR and HAVE_MEMMOVE to define them as 1 rather than 0.
Unfortunately, because of the way Unix autoconf works, the default setting has
to be 0. You may also want to make changes to other macros in config.h. In
particular, if you want to force a specific value for newline, you can define
the NEWLINE macro. The default is to use '\n', thereby using whatever value
your compiler gives to '\n'.
(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.
rem Mark Tetrode's commands
copy config.in config.h
rem Use write, because notepad cannot handle UNIX files. Change values.
write config.h
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.
(2) Compile dftables.c as a stand-alone program, 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.
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.
rem Mark Tetrode's commands
rem Compile & run
cl -DSUPPORT_UTF8 -DSUPPORT_UCP dftables.c
dftables.exe pcre_chartables.c
(2) Copy or rename the file pcre.h.generic as pcre.h.
(3) Compile the following source files:
(3) EITHER:
Copy or rename file pcre_chartables.c.dist as pcre_chartables.c.

OR:
Compile dftables.c as a stand-alone program, 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.
and link them all together into an object library in whichever form your system
keeps such libraries. This is the pcre C library. If your system has static and
shared libraries, you may have to do this once for each type.
The tables in pcre_chartables.c are defaults. The caller of PCRE can
specify alternative tables at run time.

Some help in building a Win32 DLL of PCRE in GnuWin32 environments was
contributed by Paul Sokolovsky. These environments are Mingw32
(http://www.xraylith.wisc.edu/~khan/software/gnu-win32/) and CygWin
(http://sourceware.cygnus.com/cygwin/). Paul comments:
For CygWin, set CFLAGS=-mno-cygwin, and do 'make dll'. You'll get
pcre.dll (containing pcreposix also), libpcre.dll.a, and dynamically
linked pgrep and pcretest. If you have /bin/sh, run RunTest (three

Changes to do MinGW with autoconf 2.50 were supplied by Fred Cox
<sailorFred@yahoo.com>, who comments as follows:
If you are using the PCRE DLL, the normal Unix style configure && make &&
make check && make install should just work[*]. If you want to statically
link against the .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 hilarious results. See the configure.in
and pcretest.c for how it is done for the static test.
Also, there will only be a libpcre.la, not a libpcreposix.la, as you
would expect from the Unix version. The single DLL includes the pcreposix
interface.
[*] But note that the supplied test files are in Unix format, with just LF
characters as line terminators. You will have to edit them to change to CR LF
terminators.

additional files. The following files in the distribution are for building PCRE

These are some further comments about Win32 builds from Mark Evans. They
were contributed before Fred Cox's changes were made, so it is possible that
they may no longer be relevant.
"The documentation for Win32 builds is a bit shy. Under MSVC6 I
followed their instructions to the letter, but there were still
some things missing.
COMMENTS ABOUT WIN32 BUILDS
(1) Must #define STATIC for entire project if linking statically.
(I see no reason to use DLLs for code this compact.) This of
course is a project setting in MSVC under Preprocessor.
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
some experimental, undocumented support for building using "cmake", which you
might like to try if you are familiar with "cmake". However, at the present
time, the "cmake" process builds only a static library (not a dll), and the
tests are not automatically run.
(2) Missing some #ifdefs relating to the function pointers
pcre_malloc and pcre_free. See my solution below. (The stubs
may not be mandatory but they made me feel better.)"
The MinGW home page (http://www.mingw.org/) says this:
=========================
#ifdef _WIN32
#include <malloc.h>
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.
void* malloc_stub(size_t N)
{ return malloc(N); }
void free_stub(void* p)
{ free(p); }
void *(*pcre_malloc)(size_t) = &malloc_stub;
void (*pcre_free)(void *) = &free_stub;
The Cygwin home page (http://www.cygwin.com/) says this:
#else
Cygwin is a Linux-like environment for Windows. It consists of two parts:
void *(*pcre_malloc)(size_t) = malloc;
void (*pcre_free)(void *) = free;
. A DLL (cygwin1.dll) which acts as a Linux API emulation layer providing
substantial Linux API functionality
#endif
=========================
. 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.)
If you want to statically link your program against 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.
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 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.

for details).
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.
Also included are a set of C wrapper functions that are based on the POSIX
API. 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 header file for the POSIX-style
functions is called pcreposix.h. The official POSIX name is regex.h, but I
didn't want to risk possible problems with existing files of that name by
distributing it that way. To use it with an existing program that uses the
POSIX API, it will have to be renamed or pointed at by a link.
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, you must take care when linking programs to
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 "real" POSIX functions of the same name.
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, you will end up with an installed 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; however, as there is no standard place to install

---------------------------------
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 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.

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).

therefore needs to be compiled with the local compiler, not the cross compiler.

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

because dftables.c needs to be compiled with the local compiler, not the cross

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.

Making new tarballs
-------------------
For a non-Unix system, read the comments in the file NON-UNIX-USE, though if
the system supports the use of "configure" and "make" you may be able to build
PCRE in the same way as for Unix systems.
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.
PCRE has been compiled on Windows systems and on Macintoshes, but I don't know
the details because I don't use those systems. It should be straightforward to
build PCRE on any system that has a Standard C compiler, because it uses only
Standard C functions.
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 PCRE 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 build, three
test programs called pcrecpp_unittest, pcre_scanner_unittest, and

Character tables

pointer to a block of memory containing the concatenated tables. A call to

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 chartables.c contains the default set of tables. This is
not supplied in the distribution, but 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 chartables.c and then re-building PCRE. If you do this, you should
probably also edit Makefile to ensure that the file doesn't ever get
re-generated.
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

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:

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to `$srcdir/foo'. In other projects, it is set to
# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is `.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

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.
On a non-Unix-like system you should just copy this file into config.h, and set
up the macros the way you need them. You should normally change the definitions
of HAVE_STRERROR and HAVE_MEMMOVE to 1. Unfortunately, because of the way
autoconf works, these cannot be made the defaults. If your system has bcopy()

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
macros the way you need them. Alternatively, you can avoid editing by using -D
on the compiler command line to set the macro values.
PCRE uses memmove() if HAVE_MEMMOVE is set to 1; otherwise it uses bcopy() if

If you are going to build PCRE "by hand" on a system without "configure" you

PCRE uses recursive function calls to handle backtracking while
matching. This can sometimes be a problem on systems that have
stacks of limited size. Define NO_RECURSE to get a version that
doesn't use recursion in the match() function; instead it creates
its own stack by steam using pcre_recurse_malloc() to obtain memory
from the heap. For more detail, see the comments and other stuff
just above the match() function. On systems that support it,
"configure" can be used to set this in the Makefile
(use --disable-stack-for-recursion).])
fi
AC_DEFINE_UNQUOTED([NEWLINE], [$ac_pcre_newline_value], [
The value of NEWLINE determines the newline character sequence. On
Unix-like systems, "configure" can be used to override the default,
which is 10. The possible values are 10 (LF), 13 (CR), 3338 (CRLF),
-1 (ANY), or -2 (ANYCRLF).])
AC_DEFINE_UNQUOTED([LINK_SIZE], [$with_link_size], [
The value of LINK_SIZE determines the number of bytes used to store
links as offsets within the compiled regex. The default is 2, which
allows for compiled patterns up to 64K long. This covers the vast
majority of cases. However, PCRE can also be compiled to use 3 or 4
bytes instead. This allows for longer patterns in extreme cases. On
systems that support it, "configure" can be used to override this default.])
AC_DEFINE_UNQUOTED([POSIX_MALLOC_THRESHOLD], [$with_posix_malloc_threshold], [
When calling PCRE via the POSIX interface, additional working storage
is required for holding the pointers to capturing substrings because
PCRE requires three integers per substring, whereas the POSIX
interface provides only two. If the number of expected substrings is
small, the wrapper function uses space on the stack, because this is
faster than using malloc() for each call. The threshold above which
the stack is no longer used is defined by POSIX_MALLOC_THRESHOLD. On
systems that support it, "configure" can be used to override this
default.])
AC_DEFINE_UNQUOTED([MATCH_LIMIT], [$with_match_limit], [
The value of MATCH_LIMIT determines the default number of times the
internal match() function can be called during a single execution of
pcre_exec(). There is a runtime interface for setting a different
limit. The limit exists in order to catch runaway regular
expressions that take for ever to determine that they do not match.
The default is set very large so that it does not accidentally catch
legitimate cases. On systems that support it, "configure" can be
used to override this default default.])
AC_DEFINE_UNQUOTED([MATCH_LIMIT_RECURSION], [$with_match_limit_recursion], [
The above limit applies to all calls of match(), whether or not they
increase the recursion depth. In some environments it is desirable
to limit the depth of recursive calls of match() more strictly, in
order to restrict the maximum amount of stack (or heap, if
NO_RECURSE is defined) that is used. The value of
MATCH_LIMIT_RECURSION applies only to recursive calls of match(). To
have any useful effect, it must be less than the value of
MATCH_LIMIT. The default is to use the same value as MATCH_LIMIT.
There is a runtime method for setting a different limit. On systems
that support it, "configure" can be used to override the default.])

## -MM, not -M (despite what the docs say).
## - Using -M directly means running the compiler twice (even worse

real releases, it should be defined empty. Do not change the alignment of these

to get values from column 29 onwards. These are substituted into pcre-config

/* When compiling a DLL for Windows, the exported symbols have to be declared
using some MS magic. I found some useful information on this web page:
http://msdn2.microsoft.com/en-us/library/y4h7bcy6(VS.80).aspx. According to the
information there, using __declspec(dllexport) without "extern" we have a
definition; with "extern" we have a declaration. The settings here override the
setting in pcre.h (which is included below); it defines only PCRE_EXP_DECL,
which is all that is needed for applications (they just import the symbols). We
use:
PCRE_EXP_DECL for declarations
PCRE_EXP_DEFN for definitions of exported functions
PCRE_EXP_DATA_DEFN for definitions of exported variables
The reason for the two DEFN macros is that in non-Windows environments, one
does not want to have "extern" before variable definitions because it leads to
compiler warnings. So we distinguish between functions and variables. In
Windows, the two should always be the same.
The reason for wrapping this in #ifndef PCRE_EXP_DECL is so that pcretest,
which is an application, but needs to import this file in order to "peek" at
internals, can #include pcre.h first to get an application's-eye view.
In principle, people compiling for non-Windows, non-Unix-like (i.e. uncommon,
special-purpose environments) might want to stick other stuff in front of
exported symbols. That's why, in the non-Windows case, we set PCRE_EXP_DEFN and
PCRE_EXP_DATA_DEFN only if they are not already set. */

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

handling this, I had resort to some messy hackery that does a test at run time.
