Description

import cv causes a silent segfault. gdb traces (below) point to numpy problem. My python version is 2.6, numpy version is 1.2.1.

This appeared to me a cmake problem. find_package() finds a wrong python installation (in my case, in /opt/local/..., installed by macports), different from what is executed from console command line. This results in a different set of headers from numpy used during opencv build. The path to numpy headers is logged to console by the cmake script, so one can check whether the correct path is used. I have deactivate the macports python installation, rebuilt opencv and python bindings started working.

Thanks to Vadim for solving this issue!

However I leave this bug as open in case one finds a way around cmake find_package.
