Hello.
Thanks for replying.
OK, which file do I check with 'nm'?
The one where the class TAdLayoutApplication is implemented?
Or the four ones that references (calls) functions in TAdLayoutApplication?
(What is "typeinfo" anyway? Class declaration? Implementation?)
Unchecking 'symbols hidden by default' didn't make any difference.
I didn't find any symbol stripping option than was checked.
I'm running Tiger, are you running Leopard?
I tried on an Intel Mac with Tiger and the error still comes from
...powerpc-apple-darwin8...
Regards
