Well, that's the prototype, but which .a/.so does the code appear in?

The LD_LIBRARY_PATH tells the run-time linker where to find shared
libraries at run time.  This variable is not consulted at link time,
which is when I suspect configure is deciding you don't have
those libraries.

Personally, I do this:

./configure --x-includes="/usr/openwin/include -I/usr/local/include"
--x-libraries="/usr/openwin/lib -L/usr/local/lib"

Note the tricky -I and -L bits.  It's yuck, but it works.

You still need the LD_LIBRARY_PATH, but that's when you want to
run your final exe

Hope this helps.

Mitch.
