Re: [Visualpython-users] Ubuntu packages

[Tony R. <To...@br...>]

ubuntu package segfaults in python2.5/2.6
i modified the debian package to allow python2.6... segfaults in 2.6 but works perfectly on 2.5 in Karmic.

Python 2.6.2+ (release26-maint, Jul 24 2009, 16:16:12)
[GCC 4.4.1] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import cvisual
Segmentation fault (core dumped)

looks like the reason it keeps failing is that the default python in the upcoming Ubuntu release is python2.6 and per this link:

http://vpython.wikidot.com/forum/t-97105

there is still some issues with 2.6 and vpython? or is that solved and the package just needs to be rebuilt against 2.6? (read that visual needs to be compiled against a specific version at a time).  not sure if pythonboost is 2.6 ready per that last link in ubuntu; 2.6 isnt even out of experimental in debian AFAIK.

when i "import cvisual", is it actually pulling from:

/usr/lib/python2.6/dist-packages/cvisualmodule.so.3.0.0 (+symlinks)
--or--
/usr/lib/python2.5/site-packages/cvisualmodule.so.3.0.0 (+symlinks)

? i was going to try and repeatedly replace it with one compiled from source, and maybe mess with the C++ code.  im not particularly knowledgeable of the language but i can help in whatever way need be if possible.  ill run under 2.5 for now.

Fully agreed. That's why I keep building .debs as well over installing from
source and getting into the shallows of an unmaintainable system over the
course of time. After all, VPython is not the only library I need to add to
get my stuff going.

Indeed, very true! It's so much more understandable knocking up a script in no
time to place multi-dimensional data in a 3D scene with it. The other gem is
of course Mayavi2 for this purpose ...
