C Header Files Inclusion
Anark10n:
Hey there
New to the forum, searched all over for an answer to the problem I'm having, didn't find it. New to using code blocks as well, got a problem with including my header files, probably with linking, not sure, but it keeps giving me the same error message: undefined reference to '_<function_name>'. Any clarity on the problem would be appreciated. Side note: the code compiles without problem in visual studio express.
Thanks in advance to anyone who replies...

You have a linking problem... probably missing file or library

FYI:
Visual Studio can automatically include some libraries and also uses #pragma commands to include libraries.

Thanks for the replies, but it is still giving me the same error message. Thought it might just windows only bug so i tried it on a Linux machine seeing as it usually comes with the GCC compiler pre-installed with all the necessary files, and it still gave me the same error message.

The problem can happen, if you mix c++-code with c-code.
If that's the case, you should read this: http://www.parashift.com/c++-faq-lite/mixing-c-and-cpp.html .
