As part of this, we import bpf_filter.c from NetBSD. Even though that file is part of the NetBSD kernel, it is also used by userland (as is clear here). Our LWIP service has its own bpf_filter.c implementation but that implementation has certain limits (e.g. on program size) that are fine for a system service but should not apply to userland. The libpcap code has a number of blocks guarded by __NetBSD__, but none of those blocks apply to MINIX 3. In particular, some of the alignment logic used for NetBSD may in fact not work in our case.

|
[
|

.SH DESCRIPTION
|
|
.LP
|
|
When run with the
|
|
.B \-\-cflags
|
|
option,
|
|
.I pcap-config
|
|
writes to the standard output the
|
|
.B \-I
|
|
compiler flags required to include libpcap's header files.
|
|
When run with the
|
|
.B \-\-libs
|
|
option,
|
|
.I pcap-config
|
|
writes to the standard output the
|
|
.B \-L
|
|
and
|
|
.B \-l
|
|
linker flags required to link with libpcap, including
|
|
.B \-l
|
|
flags for libraries required by libpcap.
|
|
When run with the
|
|
.B \-\-additional-libs
|
|
option,
|
|
.I pcap-config
|
|
writes to the standard output the
|
|
.B \-L
|
|
and
|
|
.B \-l
|
|
flags for libraries required by libpcap, but not the
|
|
.B \-lpcap
|
|
flag to link with libpcap itself.
|
|
.LP
|
|
By default, it writes flags appropriate for compiling with a
|
|
dynamically-linked version of libpcap; the
|
|
.B \-\-static
|
|
flag causes it to write flags appropriate for compiling with a
|
|
statically-linked version of libpcap.
