Unable to link to opengl libraries? DOS / MSVC

Is there something wrong with this link.exe command line? OpenGL32.lib and Glu32.lib are found at both of the LIBPATH directories. Is it possible the libraries are somehow incompatible? Is there a way to have the link.exe say that instead of unresolved external symbol? Googling shows that this error usually means the libraries are not found, but they are there.

It seems likely given your success with Cygwin and MSYS that these are Cygwin/GCC or MinGW/GCC export libraries and not MSVC export libraries. They will not be recognised as valid by Microsoft's linker, and will be ignored.

The correct OpenGL32.lib and Glu32.lib files are part of the Windows SDK. For the VS2008 SDK, it is at C:\Program Files\Microsoft SDKs\Windows\v6.0A\Lib (your installation may vary).

Glaux.lib is apparently deprecated and is no longer included in the Windows SDK. Download and install the older VS2005 SDK to obtain the header and export libraries if you need them. The older SDK will be installed at "C:\Program Files\Microsoft Visual Studio 8\VC\PlatformSDK" while the VS2008 SDK is at "C:\Program Files\Microsoft SDKs\Windows\v6.0A", you can simply copy the necessary files to the corresponding folder in the newer SDK.

You could of course just build with VS2005 or earlier rather than mess with the SDK.
