For example, since several months I cannot build py-matplotlib consistently any more - on most machines it fails, on one it succeeds. And graphics/qgis always dies with a signal 11. See bug #221622. And yes, I have already upgraded to gcc6, and it is the same - py-matplotlib cannot be recompiled except on one machine, and graphics/qgis (freshly recompiled) dies with a signal 11 after a few seconds. It would be interesting to have a py-numpy port which does not pull in gcc6= but rather uses the system's clang (which should be capable enough on 11.1). As a first try, running python2.7 setup.py build -j 4 install --prefix /tmp/z seems to compile o.k. (but not install due to complaints about PYTHONPATH). So, could the maintained of py-numpy create a version of the port which does not use gcc? -- Martin --=20 You are receiving this mail because: You are the assignee for the bug.=
