\`configure' configures pcap 1.10.6 to adapt to many kinds of systems.

Usage: $0 [OPTION]... [VAR=VALUE]...

To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE.  See below for descriptions of some of the useful variables.

Defaults for the options are specified in brackets.

Configuration:
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print \`checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for \`--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or \`..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
                          [$ac_default_prefix]
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
                          [PREFIX]

By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.

For better control, use the options below.

Fine tuning of the installation directories:
  --bindir=DIR            user executables [EPREFIX/bin]
  --sbindir=DIR           system admin executables [EPREFIX/sbin]
  --libexecdir=DIR        program executables [EPREFIX/libexec]
  --sysconfdir=DIR        read-only single-machine data [PREFIX/etc]
  --sharedstatedir=DIR    modifiable architecture-independent data [PREFIX/com]
  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
  --runstatedir=DIR       modifiable per-process data [LOCALSTATEDIR/run]
  --libdir=DIR            object code libraries [EPREFIX/lib]
  --includedir=DIR        C header files [PREFIX/include]
  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]
  --infodir=DIR           info documentation [DATAROOTDIR/info]
  --localedir=DIR         locale-dependent data [DATAROOTDIR/locale]
  --mandir=DIR            man documentation [DATAROOTDIR/man]
  --docdir=DIR            documentation root [DATAROOTDIR/doc/pcap]
  --htmldir=DIR           html documentation [DOCDIR]
  --dvidir=DIR            dvi documentation [DOCDIR]
  --pdfdir=DIR            pdf documentation [DOCDIR]
  --psdir=DIR             ps documentation [DOCDIR]

System types:

# These are the variables that are used in Makefile, pcap-config, and
# libpcap.pc.
#
# CFLAGS: inherited from the environment, not modified by us except
# for flags required for the platform for which we're building (and
# except temporarily during tests that involve compilation).  Used only
# when compiling C source.
#
# LDFLAGS: inherited from the environment, not modified by us.
#
# LIBS: inherited from the environment; we add libraries required by
# libpcap.  Libraries that the core libpcap code requires are added
# first; libraries required by additional pcap modules are first
# added to ADDITIONAL_LIBS, and only added to LIBS at the end, after
# we're finished doing configuration tests for the modules.
#
# LIBS_STATIC: libraries with which a program using the libpcap *static*
# library needs to be linked.  This is a superset of LIBS, used in
# pcap-config, so that "pcap-config --libs --static" will report them.
# Initialized to LIBS.
#
# REQUIRES_PRIVATE: pkg-config package names for additional libraries
# with which a program using the libpcap *static* library needs to be
# linked and for which a .pc file exists.  This is used in libpcap.pc,
# so that "pkg-config --libs --static" will report them, and so that
# those libraries will be determined using the library's .pc file, not
# from our .pc file.  Initialized to an empty string.
#
# V_CCOPT: additional compiler flags other than -I and -D flags
# needed when compiling libpcap.  Used in Makefile for both C and
# C++ source.
#
# V_DEFS: additional -D compiler flags needed when compiling
# libpcap.  Used in Makefile for both C and C++ source.
#
# V_INCLS: additional -I compiler flags needed when compiling
# libpcap.  Used in Makefile for both C and C++ source.
#
# ADDITIONAL_LIBS: additional libraries with which the libpcap dynamic
# library needs to be linked.  Used in Makefile; not used in pcap-config
# or libpcap.pc, as, in all platforms on which we run, if a dynamic
# library is linked with other dynamic libraries, a program using
# that dynamic library doesn't have to link with those libraries -
# they will be automatically loaded at run time.  Initialized to an
# empty string.
#
# ADDITIONAL_LIBS_STATIC: additional libraries with which a program
# using the libpcap *static* library needs to be linked.  This is used
# in pcap-config, so that "pcap-config --libs --static" will report
# them.  Initialized to an empty string.

		    # compile time, and thus always says "that

# in which the libpcap shared library is installed, and the install
# prefix /usr (meaning we're not installing a system library), provide
# the rpath option.
#
# (We must check $prefix, as $libdir isn't necessarily /usr/lib in this
# case - for example, Linux distributions for 64-bit platforms that
# also provide support for binaries for a 32-bit version of the
# platform may put the 64-bit libraries, the 32-bit libraries, or both
# in directories other than /usr/lib.)
#
# In AIX, do we have to do this?
#
# In Darwin-based OSes, the full paths of the shared libraries with
# which the program was linked are stored in the executable, so we don't
# need to provide an rpath option.
#
# With the HP-UX linker, directories specified with -L are, by default,
# added to the run-time search path, so we don't need to supply them.
#
# For Tru64 UNIX, "-rpath" works with DEC's^WCompaq's^WHP's C compiler
# for Alpha, but isn't documented as working with GCC, and no GCC-
# compatible option is documented as working with the DEC compiler.
# If anybody needs this on Tru64/Alpha, they're welcome to figure out a
# way to make it work.

# a GCC-compatible compiler and a vendor compiler, we need to work with
