Hi, iv been working with DirectX and i now want to try out OpenGL and i cannot seem to get it to work. I have included the library files needed, and i ran a sample code from a tutorial and im getting errors in my gl.h file. c:\oglsdk\include\gl\gl.h(1151) : error C2144: syntax error : missing ';' before type 'void' c:\oglsdk\include\gl\gl.h(1151) : error C2501: 'WINGDIAPI' : missing storage-class or type specifiers c:\oglsdk\include\gl\gl.h(1151) : fatal error C1004: unexpected end of file found Line 1151 in gl.h is: WINGDIAPI void APIENTRY glAccum (GLenum op, GLfloat value); I have no clue what is wrong or where to start. It would be much appreciated if anyone could help. Regards, Cribs

Before you include your GL.H and GLU.H, you will need to have a:
#include

You need to include windows.h BEFORE gl.h is included. This will define WINGDIAPI and your troubles will be gone :-).

hello.obj : error LNK2001: unresolved external symbol _glutDisplayFunc@4
hello.obj : error LNK2001: unresolved external symbol _glutCreateWindow@4
hello.obj : error LNK2001: unresolved external symbol _glutInitWindowPosition@8
hello.obj : error LNK2001: unresolved external symbol _glutInitWindowSize@8
hello.obj : error LNK2001: unresolved external symbol _glutInitDisplayMode@4
hello.obj : error LNK2001: unresolved external symbol _glutInit@8

If you are using external libraries such as GLUT you need to download them and link with them.

I think GLUT is available here: http://www.xmission.com/~nate/glut.html
