Linking problems with OpenGL and BenchmarkDemo

[jesperd]

Hi,

I'm trying to run the BenchmarkDemo with USE_GRAPHICAL_BENCHMARK.

I have added
#define USE_GRAPHICAL_BENCHMARK true

in the main.cpp.
When I compile, I get some linking errors:

I use MS Visual Studio 9.0.
I think it is a linking problem, but I can't see how i configure MS-VS9.0 such that the BenchmarkDemo works in graphical mode..

Any help??

You can re-create working MSVC project files using cmake-gui (part of CMake) and enabling the USE_GRAPHICAL_BENCHMARK setting (don't manually #define it in a C++ file). Then re-create project files.

This will add the proper library dependency to the BenchmarkDemo.
Thanks,

Thanks Erwin. Sometimes it is so simple that you missed the point.
