Technically this is is off topic since it is related to platform
specifics (linking is always platform specific), not the C++ language
proper. If you have further questions, you should direct them to a VC+
+ group or forum. See FAQ 5.9.
<OT>Have you included math_types.cpp in your project?</OT>
Ok I will try to find som VS group.
<OT>Found out that 3 different files/classes contained a function called
Norm, this seems to be the problem (eventhough its allowed on linux)</OT>
