Hi,
I'm trying out petsc4py, but running into trouble. While it's hosted on
http://code.google.com/p/petsc4py/, there doesn't seem to be any mailing
lists/forums. Where is the best place to get support?
Going out on a limb, I'll post my problem here for now :) I reported an
ubuntu bug here: https://bugs.launchpad.net/ubuntu/+source/petsc4py/
+bug/232036
I also tried compiling myself with SVN numpy.
I edited setup.cfg in the petsc4py-0.7.5 build dir:
[config]
petsc_dir = /usr/lib/petsc
petsc_arch = linux-gnu-c-opt
[build_ext]
debug = 0
[sdist]
force_manifest=1
[bdist_rpm]
group = Libraries/Python
vendor = CIMEC <http://www.cimec.org.ar>
packager = Lisandro Dalcin <dalcinl at users.sourceforge.net>
doc_files = README.txt docs/*.txt
config reads as follows:
$ python setup.py config
running config
----------------------------------------------------------------------
PETSC_DIR: /usr/lib/petsc
----------------------------------------------------------------------
PETSC_ARCH: linux-gnu-c-opt
language: CONLY
compiler: /usr/bin/mpicc
scalar-type: real
precision: double
----------------------------------------------------------------------
and when I try and import petsc I get a segfault
$ python
Python 2.5.2 (r252:60911, Apr 21 2008, 11:17:30)

>>> import petsc4py.PETSc
Segmentation fault
This is on an ubuntu hardy (8.04) AMD64 machine:
$ uname -a
