Hello GAPers,
I'm setting up GAP on a Linux PC. The text version goes OK, but xgap doesn't
work: gap starts and no input can be fed to the gap subprocess.
Compilation had worked fine, though. just a minor change in undefined
signals.
To make it worse, I tried to compare that with xgap on a SUN and couldn't
compile it. It ends with

cc -L/usr/openwin/lib -o xgap xcmds.o utils.o gapgraph.o gaptext.o pty.o popdial.o main.o -lXmu -lXaw -lXt -lXext -lX11 -lm
ld: Undefined symbol
_get_wmShellWidgetClass
_get_applicationShellWidgetClass
*** Error code 2

If someone has a clue for any one of these problems (mostly for Linux),
please help.
