Hi everyone,
I've spent the last few days reading man pages, FAQs and forums like
crazy, trying to resolve a simple linker error, linking my C++ app
against a static build of wxWidgets:
ld: Undefined symbols:
__ZTV14wxMenuItemList
If you ever get such mangled names from Xcode, you can unmangle them
with 'c++filt' and god knows why Xcode isn't doing the translation
automatically. The translation is:
vtable for wxMenuItemList
Now, a google search pointed me to a FAQ telling me that the linker
is trying to tell me that I probably forgot to implement a virtual
function that wxMenuItemList is supposed to inherit from its
superclass - not telling me what function that would be.
How do I figure out what's missing? I've gone to depths of ld and gcc
I never wanted to go (and would have thought that Xcode should make
that unnecessary) and this is the final step that's missing to
complete the port of a major project from CFM/CW to MachO/Xcode.
Thanks for any help,
Stefan
