great news (at least for me) - after compiling for gmake and running the Tut 01 Hello Triangle i finally see this bloody white triangle on black font. Thanks to everyone Can finally start reading about OpenGL now.

all3fox: Did you post the complete compiler output, specifically: is there no message about a file not being found?
sorry i didn't notice that question at night. Yes, it was the complete output from codeblocks. No "file not found" or other messages.
