You may also want to consider letting it load dynamically at runtime rather than linking the static .a file at compile-time. Chances are what it was looking for was dlopen() and friends, which are in libc on FreeBSD. They are a part of libc on my Linux systems as well though, so not sure why it'd be trying to link against another library, though admittedly I know a lot more about development for FreeBSD than for Linux. - mdh ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
