Thread: Trouble with multiple symbols

I am compiling a project for a Computer Science class and I get redefined symbols EVERYWHERE in the linker so eventually I just FORECED output.

Here are the errors, I can't display the code, there are too many files and too long of code to scan through without a find command.

I checked that every include I ran used #ifndef and #def for their preprocessor flags. But for some reason MS won't leave me alone, but I think it works on FreeBSD.

Code:

Onedwalk.cpp
Sixflips.cpp

Here are SOME of the errors, there are 1280 more

btw:
I used the FORCE option so they are labled as warnings and second definitions (WHICH THERE ARE NONE!) are "ignored"

hmm... weird.

are you sure you are including apstring.cpp in the project. it doesn't look like it because it isn't being linked.

MBCS I see.
