More problems with Suse 6.1

[Benedikt Stefansson]

I've been running Swarm on a machine installed from Suse 6.0 and had no
problems installing Swarm 1.4.1 there from the RedHat RPMs. Now a
machine with 6.1 is giving me grief. The recent thread on this was
inconclusive, I'm wondering if anybody has figured out what is the
problem here.

I've installed everything from RPMs on either the Suse CD-ROMs or the
Swarm 1.4.1 CD-ROM, made sure that I had tcl/tk 8.0, libffi, libxpm etc. 

The symptoms are as follows: I can compile heatbugs but the linker
provides warnings that all the Swarm library classes that are subclassed
from in the code have undefined type and size (see LISTING 1 below). The
app segfaults immediately when run in GUImode (i.e. the default) but can
run in batchmode without problems. This last part puzzles me, because it
indicates that the libraries are not out of whack with the libc,
libobjc, egcs compiler etc. that Suse installs (which was the gist of
the recent thread). GDB gives no trace since the app segfaults
immediately.

Any thoughts on how to fix this?

I've also included the output of ldd heatbugs in LISTING 2.
