After downloading the October 2002 version of the Microsoft SDK I noticed that I''m getting undefined symbols __ftol2() in the GLAUX.LIB that came with the SDK when building programs. After doing some research, I think the problem is that __ftol2() is a .NET function. The old GLAUX.LIB that comes with my VC++6 only has __ftol(). I think that maybe Microsoft compiled the GLAUX.LIB in the new SDK with the wrong version of the C-Runtime library (they used a .NET version maybe?). I''m just guessing here though. Has anyone else here encountered this problem before and did you figure out what was causing it? My solution was just to replace the new GLAUX.LIB with the GLAUX.LIB from my original VC++6 installation.
