Hi Matthew
I'm not familiar with eclipse as a C++ IDE but I wonder if you have
declared the compiler constants -DCORE_EXPORT , -DGUI_EXPORT and
- -DPYTHON_EXPORT. It should be fine to declare them as empty vars if you
are under Linux. This is just a shot in the dark since as I mentioned
I've never tried to build under eclipse.
Regards
Tim
