Hi there, I often encounter the problem, that I dont really know what to do, when my gcc compiler gives me an error message while compiling a c++ programm. Recently I got a "error: multiple types in one declaration" And it took me a really long time to figure out that I just forgot a semicolon after a class declaration. Is there anywhere a more detailed explanaition of gcc error messages? Maybe with a list of things i should check, when a certain error occurs? Thanks, Markus
