NAME

       pcap-config - write libpcap compiler and linker flags to standard output

SYNOPSIS

       pcap-config [ --help ] [ --version ] [ --cflags ]
                   [ --libs | --additional-libs ]
                   [ --static | --static-pcap-only ]

DESCRIPTION

       pcap-config  writes  to  the standard output various compiler and linker flags required to
       build a user program with libpcap.  By default, it writes flags appropriate  for  building
       with  a dynamically-linked version of libpcap; see below for static linking.  Depending on
       the manner of libpcap installation, some options or their combinations may  produce  empty
       output - this is by design.

OPTIONS

       --help Produce a help message and exit.

       --version
              Produce  libpcap  version and exit.  The version is the contents of VERSION file in
              libpcap source tree rather than the result of pcap_lib_version(3PCAP).

       --cflags
              Produce the -I compiler flag required to include libpcap's header files.

       --libs Produce the -L and -l linker flags required to  link  with  libpcap,  including  -l
              flags for libraries required by libpcap.

       --additional-libs
              Produce  the  -L and -l linker flags for libraries required by libpcap, but not the
              -l flag to link with libpcap itself.

       --static
              This option causes --libs and --additional-libs to produce linker flags appropriate
              for static linking with libpcap.

       --static-pcap-only
              This option causes --libs and --additional-libs to produce linker flags appropriate
              for static linking with libpcap and  dynamic  linking  with  all  other  libraries,
              including libraries required by libpcap.

EXIT STATUS

       pcap-config exits with a non-zero status when invoked with an invalid command-line option,
       and with status 0 otherwise.

BACKWARD COMPATIBILITY

       Before libpcap release 1.10.2 pcap-config did not treat invalid command-line options as an
       error.  The  --static-pcap-only  flag  became  available  in  libpcap release 1.10.2.  The
       --static flag became available in libpcap release 1.1.0.
