Recompiling sfepy now I have only one error in tests/test_input_acoustics.py. Here it is the output:
I guess you needed no recompilation in this case - sfepy uses umfpack only as an external package with no link-time dependence.
So, if I understand correctly I don't need the UMFPACK headers either? Maybe just installing the umfpack scikit with the runtime UMFPACK library should be sufficient, right? I ask this because the runtime library is automatically installed by scipy (on ubuntu) while the -dev package is not... and I'm taking notes on the correct procedure on ubuntu 9.04. At the end I can post the instructions somewhere.

This is strange, look at what I get:
sfepy: nls: iter: 0, residual: 1.116698e+07 (rel: 1.000000e+00) sfepy: rezidual: 0.00 [s] sfepy: solve: 0.00 [s] sfepy: matrix: 0.00 [s] sfepy: nls: iter: 1, residual: 8.460917e-08 (rel: 7.576731e-15) ... ../input/acoustics.py solved
- no singular matrix warning. I have tested with numpy 1.2.1, scipy 0.7.0, umfpack 5.2.0 on gentoo, latest git version of sfepy. But I do not use the scikit (good old deprecated scipy.sparse.linalg.dsolve.umfpack). Let me check with the latest scikit
- yes, it works too.
I've tested with the numpy 1.2.1 and scipy 0.7.0 shipped with ubuntu and I get the same error (see my first mail).
What is you swig version?
I use the swig version in ubuntu 9.04 that is the 1.3.36.
