[vtk-developers] libc++ problem on OSX

[Biddiscombe, John A.]

For compatibility with some other libraries, I tried compiling paraview on OSX using libc++ instead of libstdc++.
Everything is fine except some link errors coing from vtkCocoa… classes. I have never worked with these before, but see all the classes causing me trouble emanate from code which has an mm extension.

Looking at the make rules, I cannot see anything obviously wrong, but does anyone know of a reason why the vtkCocoa classes cause this trouble. Are they using a libstdc++ from the system (via some cocoa related link) which I can’t work around?

Thanks for any hints.
