I am modifying a file in a large c++ software program. I need to "#include" a data class into the header of the file I am working with, but when I do that (and compile) I get a ton of "syntax" errors. I went back through all the other header files and added the "guards":
Code:
#ifndef HEADERNAME_H
#define HEADERNAME_H
// all code
#endif
but i still get these errors. If I comment out the new #included class, everything runs fine. Does anyone have any ideas as to what could be the problem?

Thanks
