DOLFIN

problems with File IO

Asked by L Olson

When I make two File streams either in Python or C++, Dolfin crashes. For example, in Python:

from dolfin import *
f = File('f.pvd')
g = File('g.pvd')

results in:

====

As a result, demos like stokes-iterative fail.

Installed using modified Dorsal (unstable). Mac. Dolfin 1.2.0+

Any ideas on where to look to fix this?

This one is still stumping me. Does anyone have any ideas?

Ok, I think I've narrowed this to a boost issue. It seems that boost was built with macports gcc, but links to the system libstdc++. This is causing issues. I'll mark this closed.
