I''m really sorry to ask such a stupid question but... could someone tell me what to do if I need the OpenGL types and funtions in two (or more) different .cpp files? If I try to #include gl.h in two files the compiler (vc++ 6) start complaining like this c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : error C2144: syntax error : missing '';'' before type ''void'' c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : error C2501: ''WINGDIAPI'' : missing storage-class or type specifiers c:\program files\microsoft visual studio\vc98\include\gl\gl.h(1152) : fatal error C1004: unexpected end of file found I''m tired of putting all my gl related code in only one file Please Help If You Can Cheers
