Ok, that's a step forward. Now try to run mshr's demos instead of Dolfin's. They are essentially the same, but this should make sure that you are getting the CSG primitives and mesh generation functionality from mshr and not from Dolfin.
If you have mshr's source available you will find the demos there. If not, download them from here: https://bitbucket.org/benjamik/mshr/src/2b0ce1558f3e502e57f06e5bdfd18f1e940cff96/demo/python/?at=master Benjamin 2014-11-07 14:37 GMT+01:00 Kat M <[email protected]>: >> There is probably a check in the demo files that checks if Dolfin is >> built with cgal support.
