KeyError: 'init_mesh'

Are you using the latest revision of the development branches of the
FEniCS packages? These are under heavy development and I would recommend
to revert back to the 1.1 tag of FFC, UFL, and DOLFIN and 2.1.0 for UFC.

Thanks so much for all your attentive help. The support you provide is beyond outstanding.

Still having some issues. I went to 1.1 on everything and ran instant-clean. Here's my current error, followed by the instant compile log.

I do appear to have two versions of swig.

Recent install:
/usr/local/share/swig/2.0.9

Older install
/usr/share/swig/1.3.40

However, the temporary .cxx file was generated with the correct, newer version. From the file:
...
 * This file was automatically generated by SWIG (http://www.swig.org).
 * Version 2.0.9
...

Thanks Martin Sandve Alnæs, that solved my question.

I experience the same issue as the original poster for something as simple as

from dolfin import *
mesh = UnitIntervalMesh(20)
V = FunctionSpace(mesh, "CG", 1)

Going back to 1.1.0 is not an option for me right now since I would like to try out a fix for another Dolfin bug.

Since this malfunction is so fundamental, I'm thinking it's something that the devs aren't seeing at all on their machines.
Anything I could do to debug?

You probably have a mismatch in the FFC/UFC/DOLFIN versions installed/picked up. init_mesh is a function that has been removed from UFC, but your FFC still thinks it's there.

You need to make sure that the python modules of ufc is installed correctly.

%(init_mesh)s is in:

  src/utils/python/ufc_utils/dofmap.py

for both 2.0.1 and 2.1.0 but not in trunk. You most probably have an old ufc_utils hanging around.

I think it is the other way around :)

The templates from ufc_utils expects a form with "init_mesh", which ffc
does not generate anymore.

Indeed:

>> import dolfin
>> dolfin.__file__
'/home/nschloe/Work/FEniCS/lib/python2.7/site-packages/dolfin/__init__.pyc'
>> import ufc_utils
>> ufc_utils.__file__
'/usr/lib/python2.7/dist-packages/ufc_utils/__init__.pyc'

The problem is with Dorsal I think:
All packages are installed into

~/Work/FEniCS/lib/python2.7/site-packages/

except UFC which sits in

~/Work/FEniCS/lib/python2.7/dist-packages/.

Did you try removing the old installation before installing the new
one?

That's what Garth suggested suggested at https://bugs.launchpad.net/dorsal/+bug/1103153 too. -- And it worked. Thanks!
