Hi,

 

I managed to install CGAL 3.4 but get the following linking error when trying to make the Arrangement_on_surface_2 demo:

This should work unless it involves constant data structures referencing symbols from auto-imported DLLs

The lines starting with "Info: resolving Qt..." are no problem, I got them with CGAL 3.3.1 too. Can anybody help with the undefined references in libCGAL_Qt3.a? Thanks in advance...

 

Kind regards
