Qt version of OpenGL SuperBible Triange - undefined reference GLBatch

[vertmont]

I'm new to Qt and I'm trying to implement the examples in the OpenGL SuperBible which uses GLTools. I'm using Qt Creator (Qt Creator 2.0.94 (2.1.0-rc1)).
I expect that I'm missing something simple but I need some help.

Thanks for any help.

I run qmake and then Build Project.
I'm getting the following error from Build Project: Compile Output
These are all defined in GLTools.h and are in the gltools.lib

Looks like you are building with MinGW GCC, but trying to link with Microsoft Visual C++ libraries. The two compilers are not compatible and libraries built with one cannot be mixed with the other.
