hi all,
A few minor nits with mpl 0.65:
1. I just tried to build an rpm for mpl via bdist_rpm, and it unfortunately
fails. The problem is the extra -debuginfo rpm which gets generated in the
process, which then causes the setup.py process to abort. It would be very
nice to be able to use bdist_rpm to cleanly generate RPMs out of the sources,
for handling installation via yum on multiple boxes.
2. I think there are some hardcoded paths in mpl which shouldn't. I installed
it (after the rpm failure) with 'install --prefix=/usr/local', and the date
demos fail:
planck[examples]> python date_demo1.py
Could not find bitmap file "/usr/share/matplotlib/home.xpm"; dying
Note that:
planck[examples]> d /usr/local/share/matplotlib/home.xpm
-rw-r--r-- 1 root 5135 Jul 20 12:13 /usr/local/share/matplotlib/home.xpm
which is as it should, since I specified my prefix as /usr/local. The runtime
code should not assume that the base prefix is necessarily /usr, since this
can be changed at installation time by the user.
3. The dates stuff also has problems when running in non-english locales:
In [1]: run date_demo2.py

If I switch to the US locale, the code runs (until the crash listed in #2
because of the path problem).
Anyway, this is _my_ Christmas gift to matplotlib
Cheers,
