# Compilation Options
#
# User-definable switches:
# WITHOUT_CRYPTO	Build without IPSEC or TCPMD5 decryption.
# WITHOUT_IPV6		Build without IPV6 support.
#
# Defaults:	WITH_CRYPTO WITH_IPV6

# The --without-crypto flag needs to be explicitly specified. The
# configure script gets confused if you specify --with-crypto and
# thinks this means you *don't* want crypto.

#
# Force the use of the shared library from the libpcap port.
# Don't rely on pcap-config, it is still not ready for prime time.
#
# When building tcpdump against a particular pcap version, it expects to
# find a built, untarred source tree in the parent of the work tree.
# Build a symlink farm which points to the installed versions of the
# required files, in order to produce the files it wants without
# requiring that the libpcap distfile be untarred.
# Furthermore, tcpdump's aclocal.m4 only looks for the static version
# of this library, so we need to perform another substitution.
