PCAP-CONFIG(1)

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.
