1. Extract the .o files from the static xforms lib with
ar -x libforms.a
gl.o is already there, at least on linux ELF
2. In the xforms directory, file mkconfig.h gives the command to
to make a shared library. Use it to make a new libforms.so.xxx
Note that xforms links in the Xpm library, so if you skip this
part, you will have to add -lXpm when you compile.
I guess there is a reason that Xpm is linked into Xforms...TC?
