Once again I'm stuck with my AIX pkgsrc environment. This time it's with
lang/perl5. I really appreciate anyone reading on...


Do you have a coredump?

Joerg


I do! Thanks for the hint. Below is what gdb says. I guess here's the
problem: I don't know if perl is looking for the wrong symbol name or if
the symbol we're looking for isn't here (and should be).


Have you build with -g? It looks like it is calling a null pointer...

Joerg



Hi Joerg,

After a lot of gnashing of teeth I tried to build with `-ggdb' andwithout any `-O' option. Now we get some line numbers in the trace andsome variables. Not that I really know what I'm doing, but I still can'ttell what is coming back with a null pointer or what to do about it.


Hoping for any kind of guidance here...

Louis
