Package: casacore
Version: 2.3.0-3
Severity: important
Tags: patch
User: [email protected]
Usertags: origin-ubuntu artful ubuntu-patch
In Ubuntu, we discovered that python-casacore was failing to build from
source on i386 after casacore had been rebuilt for the python3.6 transition.
Surprisingly, the reason for this was that casacore's python3 detection - on
all architectures - had failed against python3.6 and instead linked
everything against libpython2.7. Things nevertheless continued to work,
except on i386 where python-casacore loading libpython2.7 into a running
python3.6 process caused a segfault.
The amazing thing was that this managed to work anywhere else.
I've applied the attached patch to casacore in Ubuntu to add python3.6 to
the search path, fixing the misbuild. Of course, the problem will recur
when python3.7 comes out, so a better upstream fix would be nice.
Filing this bug as important, but please note that python3.6 is coming soon
in Debian at which point this should be considered serious.
Thanks,

+Description: add support for python3.6
