This is sorta stupid -- Metis is a C library, but since their header file
doesn't contain extern "C" {...} markers, we have to add those around the
#include in sparsity_pattern.cc. We then consequently run into trouble if
Metis.h includes a C++ header file as it appears to do on your system.
There is no good solution to this apart from asking Karypis for a new
Metis release -- the likelihood of which can be gauged from the fact that
there hasn't been a release for more than 10 years now...
Anyway, I think I've fixed this in our current development sources. Can you
try again with what I just checked in?
Best & thanks
W.
