Re: [Visualpython-users] Notes on Ubuntu 9.10

[Gary P. <gar...@gm...>]

PPA:  Once you've done it three or four times you get used to it.  :)

I do have to correct my earlier comment.  When I first installed the package
python-visual, it simply segfaulted on start up.  When I installed boost
from ppa, it did not segfault, but it did crash.   I misinterpreted the
error message, though.  The current error is the glibmm error mentioned
here:
https://bugs.launchpad.net/python/+bug/457688
(I had just glanced at the error, saw the letters "gl", and thought it was
an OpenGL error.)  Is that part of the boost bug?

I now have two Ubuntus: my regular OS, and one running in a VM.  My regular
os is the one where Vpython ran, but the file system became corrupted due to
the Mesa/kernel/Radeon bug.    I simply don't remember if I installed boost
packages, or compiled boost from source.  I did not have the PPA boost
installed ... I didn't know about that until yesterday.   I can't tell by
looking at what's installed because I did a complete reinstall of Ubuntu in
the meantime, hoping that one or more of my bugs would go away.

In the VM Ubuntu I installed the visual-python package, and boost from the
PPA.  That's the setup that allows me to import visual, but crashes with the
glibmm error whenever I try to create a visual object.

I have another VM, this one running Mandriva.  There's no visual rpm for
Mandriva that I'm aware of.  I'm in the process of installing the
prerequisites for visual from standard Mandriva rpm packages, and then I'll
compile visual.

I'll also see what progress I can make on the Ubuntu VM.  I'll let you know
what happens.  As you very well know, all this takes time.  What you may not
know is I have a life.   :)    I'll get it done before long.

PS  I'm beginning to wonder whether Ubuntu's policy of forcing out a new
release every six months is such a good idea after all.  We'll probably get
visual running on 9.10 just as 10.04 comes out.
