I've been meaning to revisit aclocal.m4 and the autoconf setup for a long time. Much of it was hand-spun to get around bugs or limitations in autoconf 2.9. Unfortunately, I don't have access to many of the "funny" systems to make sure that I don't delete something that looks like cruft but is actually needed.
I'd start with a modern check for libcrypto - use AC_ARG_WITH to add -L$with_libcrypto/lib to LDFLAGS and -I$with_libcrypto/include to CPPFLAGS if $with_libcrypto is not "yes" or "no", then if $with_libcrypto is not "no", use AC_CHECK_LIB with either "main" or a more modern function than the current autoconf check uses (the one that autoconf currently uses was turned into a compatability macro in OpenSSL 0.9.7, I think, which is why it usually fails). I dunno if we want to try to keep compatibility with older systems with sslEAY. Bill - This is the tcpdump-workers list. Visit https://lists.sandelman.ca/ to unsubscribe.
