Thanks Michael,

Here the ouput with verbosity=2

$python -c 'import kwant; kwant.test(verbose=2)' >& Kwant-test-verbose2.txt

And here it segfaults...

Hi Pol,

can you run kwant.test as 'kwant.test(verbose=2)' to see at which test the segfault occurs?

I don't remember all the details, but MacOSX 10.6 was a bit special in that there was some mix of 32bit and 64bit. It might be some tricky stuff ...

Best,

Michael

Thanks Michael. Well, changing directory did make a difference.
However, I get now a segmentation fault:

$python -c 'import kwant; kwant.test()'

/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/kwant/solvers/sparse.py:94:

........................SSS........Segmentation fault

Right now I don't care about the MUPS lib. Thinking on having first
kwant running ok, before reinstalling with MUPS.

It seems to be there is some minor, even obvious, but essential step
that I may be missing. The
not testing things in the same directory where kwant was untarred
should come in the install readme,
for instance. But what else could I be missing now?

Cheers,
