Re: new to swig, problems with exceptions

Dave

thanks for your help, it looks like it was the namespace that was causing
the problem.
I kept my class inside my namespace declaration but moved the %exception
clause out of the namespace and it now works a treat.
Now I can get on and use SWIG in anger, it looks like a lot of fun
once again thanks for your help

It's hard to say what might be going on here.  However, I would check a
couple
of things.   First, make sure that the %exception code is actually
showing up
in the generated wrappers.   The fact that you defined the exception
handler
in a namespace like that might have some adverse effects (like only
attaching
the exception to declarations in that namespace).    If, for some
reason, the
%exception code is missing, that would explain a crash.   It's also
possible that
there is some kind of linking problem.   Double check the
compiler/linker flags and
make sure that exceptions are enabled or compiled properly.  I know on
earlier
compilers, you sometimes had to specify extra options to make
exceptions work
correctly with dynamically loadable modules.

Cheers,
Dave
