Hello,
I have an x86_64 machine running openSUSE 13.1 with Python 2.7
and I am trying to use python-dolfin, but I am getting an error:
frodo{young}% python
Python 2.7.6 (default, Nov 21 2013, 15:55:38) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from dolfin import *
---------------------------------------------------
DOLFIN runtime dependency is not met.
Install the following python module: 'ffc'
and make sure its location is listed in PYTHONPATH.
---------------------------------------------------
But python-FFC is in fact installed (and so is dolfin):
frodo{young}% rpm -qa | grep python-FFC
python-FFC-1.3.0-5.4.x86_64
frodo{young}% rpm -qa | grep dolfin | sort
dolfin-1.3.0-2.21.x86_64
dolfin-devel-1.3.0-2.21.x86_64
libdolfin1_3-1.3.0-2.21.x86_64
python-dolfin-1.3.0-2.21.x86_64
python-dolfin_utils-1.3.0-2.21.noarch
I have googled (is that really a word?) around on the network
and found other folks who have seen the same error message,
but their proposed fixes do not seem to help. I am guessing
that I have some sort of incompatibility with some dependency,
but I have not been able to find it so far.
If I try to import ffc directly, I get a different error:
frodo{young}% python
Python 2.7.6 (default, Nov 21 2013, 15:55:38) [GCC] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import ffc

So it might appear that ufl.geometry is involved, but I have
not yet found the problem. Has anyone else seen this? Any
suggestions?
