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 no-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.
