Touching configure.in is *scarey*! Yes this part about handling dependencies is definitely a black art and they've gone to great lengths to hide it from even the developers who use automake/autoconf. > It seems that with this line in configure.in: > > CPPFLAGS="$CPPFLAGS -I$x_includes" Hmmm, I'm surprised you even got away with this.

Sounds like you must have an older version of plib in /usr/X11R6 ... now wouldn't that be funny. :-) I have seen more complicated apps like FlightGear start to develop sensitivities with link orders. No idea if either of these are related, but they are the first things that come to mind. Curt. -- Curtis Olson Human Factors Research Lab Flight Gear Project Twin Cities cu...@hf... cu...@fl...
