Stack walkbacks and catching unhandled exceptions

[Vincent Coetzee]

Dear List,

I realize that this may not be the most appropriate list to post  
development questions to, but I was led to believe that it is the only  
one that is still active. I am doing some fairly complex development  
in Objective-C on Ubuntu Linux 8.04. I have 3 problems that are  
significantly retarding my development speed that I hope someone may  
be able to help me with.

1-2. When I use Objective-C on Mac OS X, the first thing I do when I  
start developing an Application is to install an UnhandledException  
handler that gives me a full stack trace when it catches an unhandled  
exception. I would very much like to do this on Ubuntu using  
Foundation (GnuStepBase) since everytime NSObject catches a  
doesNotUnderstandSelector my App aborts and I have to bugger around  
for 10 minutes with the debugger to find out the selector, class and  
method. I have tried installing an unhandled exception handler using  
the ( mostly ) undocumented functions to no avail. All the functions I  
install never get invoked. Does anyone know how to do this with  
certainty. And secondly I can not find the companion methods in  
GnuStepBase that I use in Mac OS X Foundation to get a stack trace.  
Can some assist / suggest ?

3. I use HOMs specifically those from MPWFoundation heavily on Mac OS  
X, I can't get the damn stuff to build. I mean I thought I knew my way  
around makefiles, but that stuff boggles my mind. Has anyone managed  
to get MPWFoundation to build on Ubuntu/Debian  and if so how ?

Any assistance would be greatly appreciated, and if this indeed the  
wrong list, apologies, but where should I post ?

Many thanks
