PCAP-CONFIG(1)		    General Commands Manual		PCAP-CONFIG(1)

NAME
       pcap-config  - write libpcap compiler and linker	flags to standard out-
       put

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	 libp-
	      cap, 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 dy-
	      namic linking with all other libraries, including	libraries  re-
	      quired 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  com-
       mand-line  options  as  an  error.  The	--static-pcap-only flag	became
       available in libpcap release 1.10.2.  The --static flag	became	avail-
       able in libpcap release 1.1.0.
