pcap-config1

Usage

Overview

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

The --version flag became available in libpcap release 1.10.3.

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.
