Hello!
When linking FVWM2.0.39 using gcc on Sun-OS 4.1.4 with Openwindows 3.0
I get an "Undefined symbol _basename" fatal error message from ld, which
then exits. (For details see below.)
Question: Does any one have an idea how I can avoid this?
There is a similar problem for module FvwmPrompt, shown at the end.
(I'm more or less a novice in X, C and Unix programming, so the issue
might be silly. I just don't have any more experiended person available
locally.)
Thanks in advance!

Here is an extract from the compilation and the complete link command with
error output:

OS: Sun-OS 4.1.4
X11: Openwindows 3.0 Which I think is based on X11R5.
(We don't have libraries for Motif application
development. We only have the standard
Openwindows installation.)
FVWM: fvwm2.0.39
XPM: xpm-3.4a (libXpm.so.4.1 + libXpm.a +xpm.h)
Compiler: gcc 2.7.2 Used for both FVWM and XPM.
-----------------------------------------------------------------------------
Some notes:
I've noted that there is a call to "basename" (without leading "_")
in function "usage" in file "fvwm.c". During the compilation I get
an get warning(s) for it, as show in the listing below.
Using "nm -og" on /usr/openwin/lib/lib* ( and /lib/lib* ) gives the
following information relating to "_basename" :
> nm -og /usr/openwin/lib/lib* |grep -i basename
/usr/openwin/lib/libtt.a:tt_path.o:0000004c T __Tt_basename__FPCci
/usr/openwin/lib/libtt.so.1.1:0006e124 T __Tt_basename__FPCci
Trying to add "/usr/openwin/lib/libtt.a" to the linking does not help.

I get a similar error in FvwmPrompt. Does it have the same reason?
