cant compile

im very very new to programming so i would very much appreciate it if someone would explain why it says

16 c:\mydocu~1\hello_~1.c gltk.h: No such file or directory

how can i fix it?

What compiler are you using?

Sounds to me like you have a #include for gltk.h, and the compiler can’t find the file. Check if your include-directory is set right.

i got it from and its in a directory within the area it draws the other ones from so i type in gl/gltk.h could that be the problem?
