Linker cannot resolve OpenGL functions
« on: November 06, 2010, 06:03:10 pm »
Hello, I tried compiling the tutorial which uses OpenGL to draw a cube on the screen. However I'm getting a bunch of linker errors which probably indicate that it can't find the OpenGL functions. I thought OpenGL was included by SFML/Window.hpp?
What am I doing wrong  :x .

The errors:
1>Main.obj : error LNK2001: unresolved external symbol __imp__glClearDepth@8
1>Main.obj : error LNK2001: unresolved external symbol __imp__glClear@4
1>Main.obj : error LNK2001: unresolved external symbol __imp__glClearColor@16
1>Main.obj : error LNK2001: unresolved external symbol __imp__glEnd@0
1>Main.obj : error LNK2001: unresolved external symbol __imp__glBegin@4
1>Main.obj : error LNK2001: unresolved external symbol __imp__glDepthMask@4
1>Main.obj : error LNK2001: unresolved external symbol __imp__glRotatef@16
1>Main.obj : error LNK2001: unresolved external symbol __imp__glVertex3f@12
1>Main.obj : error LNK2001: unresolved external symbol __imp__glMatrixMode@4
1>Main.obj : error LNK2001: unresolved external symbol __imp__glViewport@16
1>Main.obj : error LNK2001: unresolved external symbol __imp__glTranslatef@12
1>Main.obj : error LNK2001: unresolved external symbol __imp__glEnable@4
1>Main.obj : error LNK2001: unresolved external symbol __imp__glLoadIdentity@0

It is indeed included by SFML, but not linked. You must link to opengl32.lib.

Ah so that's it, it works now :).
I've worked my way through the next few tutorials and SFML seems like an awesome library!  :D

Where is the Lib? I tried going to the linker and just linking it but no luck.

Which compiler do you use? I use VC++ 2008 and it can find the opengl32.lib without problems.

No that is just one asking how people got to OpenGL and this guy could possibly help me since I have the same errors as him...

But you already ask the same question here

If you get answers here, people following the other thread won't see them.

Ok sorry, I just thought that this would the thread for this and I would delete my other post so people could find the answer easier istead of looking in where did you start opengl
