It is hard to figure out what is wrong without details. See cmake output (especially lines containing OCC), it should give some informations. Or better yet, copy output here so that we can help you.
Denis, thank you for your help!I read a lot of cmake files and understood that maybe my CASROOT variable was slightly insufficient. I added several paths to this variable and all worked. Now cmake detects Opencascade libs and headers automatically.
Indeed CASROOT is a very-very important variable. I'm happy for OCC support activation. But when I tried to mesh brep files I faced some troubles. I'm working under Linux.And here I can mesh a unit box and a unit sphere, but I cannot mesh a simple model - two spheres inside a unit box (attached ell0.brep):
Info : Running 'gmsh ell0.geo -2' [1 node(s), max. 1 thread(s)] Info : Started on Fri Sep 9 16:54:42 2011 Info : Reading 'ell0.brep'... terminate called after throwing an instance of 'Standard_ConstructionError' Aborted However when I mesh this model under Windows, all works good. To load brep file into Gmsh I use this geo file: Geometry.OCCFixSmallEdges = 0; Geometry.OCCFixSmallFaces = 0; Mesh.Algorithm = 1; Mesh.Algorithm3D = 1; Merge "ell0.brep"; Windows: Gmsh 2.4.2, Gmsh 2.5.0 Linux Red Hat: Gmsh 2.4.2, Gmsh 2.5.1 nightly Thanks Mikhail Artemiev
