Build failed

which is the same for mine ... im kind of a newbie but ive always
been able to have successful builds in other compilers and I
purchased the cd version of dmc.... very frustrating... any
comments or suggestions would be appreciated.

Thanks

Does anyone know how to get opengl\windows source to compile. Any
advice would be welcomed.Thanks

The symbol _wglDeleteContext 4 is not found by the linker. So where is it? The easiest way to find it is to use grep: cd \dm\lib grep _wglDeleteContext 4 *.lib GLAUX.LIB:.__imp__wglDeleteContext 4 OPENGL32.LIB:._wglDeleteContext 4.OPENGL32.wglDeleteContext OPENGL32.LIB:_glVertex2f 8..._wglDeleteContext 4t.._wglRealizeLayerPalette 12.. Looks like it's in \dm\lib\opengl32.lib, so add that to your link command.
