CGAL users discussion list

[Michel Audette <>]

Hello,

I would like to play with the code in
examples/Mesh_3/mesh_polyhedral_domain.cpp , but I'm finding that the
build process (on Linux with gcc 4.4.3) complains about the first
line, in a manner related to template instantiation depth. I have
other CGAL-based code that builds fine, so this code has something
that gcc does not like.

/usr/local/include/CGAL/Modular_arithmetic/Residue_type.h:27,
                 from /usr/local/include/CGAL/Residue.h:31,

(a long litany of messages, many related to boost)

Can anyone comment on a workaround?

Btw, I've had answers to 2 questions today so far. This open-source
forum is working extremely well, and I want to congratulate you.

Cheers,

Michel
