Hello,
Our app is built using CW 8.3 and MS Visual C++ (it's cross-platform).
I am currently investigating whether gcc 3.3 will generate
better/faster code than CW. For that purpose, I have built a Mach-O
target in CW, and it runs fine.
Our app is built using a few static libraries. I tried to use the CW
Project importer for the whole app but there were way too many errors
and things to fix that I thought I would try to build just one library
and replace it in the main CW project.
I was able to convert one library to Xcode, and build it as a .a file.
But when I got to the linking stage, CodeWarrior started throwing link
errors my way. I don't understand why these occur:
Link Error : undefined: '__cxa_call_unexpected' (code)
Referenced from 'DigitalWet::normalize_outside_data(unsigned long*,
short)' in libBrushEngine Mach-O Debug.a
This must be in a framework somewhere, I just don't know where to look
Link Error : undefined: '_Unwind_Resume' (code)

What is '_Unwind_Resume'? It's not in my code...

What is '__cxa_pure_virtual'?

I have no idea what these errors mean.
Can anybody point me in the right direction?
Thanks,
Philippe
