Hello Christophe, 

No I can’t use them, they’re not included in the binary distribution (homebrew). And I have difficulties in making other people I’m working with compile and possibly fix compilation switches (*), so I’m stuck with the default homebrew.

By the way, what am I doing wrong with my implementation of a simple V/E/F class? I’d like to make things as simple as possible.

Thanks & Cheers!

(*) By default on our platforms gmsh won’t build the libraries, and won’t include gmshV/E/F classes (by a default make install). Moreover, we encounter a linking problem with PETSc (see next). 

Unfortunately I am not really eager to solve their problems by hand myself.
