A) the order is wrong of the libraries: forms USES X11 and m, so should be
before them on the command line: -lforms -lX11 -lm

B) this one needs "pixmap" support, so you need -lforms -lxmp (or is it
Xpm?) and THEN the other (system) libraries.

Entries in X11, aren't searched anymore as the "X11 processing" has already
been done when "-lforms" is done (and "forms" asks for them, so X11 has always
to be after forms). For dynamic (.so) libraries the order is much less
critical as the real binding is done RUN-time, not link time, but static
linked programs really need to find all the routines NOW.
And thus the libraries DO need to be specified in the right order.

Now he can't find "libforms.*" anymore. These entries are in there.
Maybe the "wrong" type of forms library for your system.
