Hi! I''ve defined a variable pi in one header file. Several other headers are accessing this var. But when I compile it, I get a linker error which says that pi is already defined in my main.obj, which also uses pi. What do I have to do? Thanks LaBas

Take a look at the Multiple cpps thread. We discussed of such problems extensively (look for the "extern" keyword parts).

Sorry for asking a question that has just been discussed.

Thank you for that hint!
