Hi again, cc'ing the matplotlib list this time,
for the latter: when building matplotlib against a fink-installed python compiled in 64bit mode
I found the check for a framework-installed Python (rev 8365) fails, and matplotlib fails to load,
because the MacOS module is not available in 64bit. Actually Apple seems to have made it
still available in their system Python, but it's likely to be a general problem on 64bit OS X installations,
and will be for python3 as well.
I believe I have fixed the patch file issue that came from an accidental edit of
the patch file (off by 1 space character). For the issues below, can you give
me some examples that show the behavior that is broken now, but fixed into your
updated patch? I haven't used matplotlib in a long time.
thanks, the fixed patch in unstable compiles and runs now.
Sorry for the late reply; I found that the issue that my extra patch addressed
actually only seems to exist for x86_64 on Snow Leopard.
It is in fact not directly related to python being built as a framework, but the
"import MacOS" used to check for the framework version fails, since the
MacOS module is not available in 64bit. Or so the python docs state, but Apple
seems to have retrofitted it somehow into their system python, so my test for
"import MacOS" worked with /usr/bin/python even on Snow Leopard.
So the test for MacOS.WMAvailable() that my patch removed can obviously stay
there for 32bit installations, and it would probably be better to just catch the
import error on 64bit systems. I'll try to work something out along those lines,
and probably send it upstream to the matplotlib folks as well, since this should
be a general problem on 64bit systems; and also the MacOS module is going
to be removed altogether in python3.x. I'll keep you posted.
I've put the import inside the check now and have it print the warning in both cases
(assuming Python is not a framework installation if it lacks the MacOS module).
I don't know if there might be an alternative way to check for the framework property
for later, and I just picked an error to raise that seemed sensible - feel free to change
that as necessary.
