link error in release version

Hi,

I have a VC++ program which uses OpenGL functions. The program works well under debug version. But if I build it in release version. It won’t compile and gives some link errors:

error LNK2001: unresolved external symbol __imp__wglDeleteContext@4
error LNK2001: unresolved external symbol __imp__wglMakeCurrent@8
error LNK2001: unresolved external symbol __imp__wglCreateContext@4
error LNK2001: unresolved external symbol __imp__glColor3f@12

What is the reason for this error? And how to fix it?

Thanks!

set your active configuration to ‘debug’. Then go to Project->Settings and copy the line in ‘object/library modules’ to the clipboard.
Next, set your active configuration to ‘release’. Go to Project->Settings and paste the line in the clipboard to ‘object/library modules’. Change the libraries from debug to release version where desired.

Greetz,

Nico

Thanks, NiCo!
