buggy Panda3D on ubuntu jaunty + i7.

Installation
#1

Really doesn’t work … :frowning:
The DirectStart seems broken and so Vec3.
I used the i386 deb on the site.
Do I need to compile the whole thing ?

#2

Huh, that’s weird. Do the same Vec3 operations fail in the normal python console (not ipython) ?

#3

on python2.5 : same result.

but on python2.6 -which is aliased to python on this machine- it works.

very strange, as python2.6 shouldn’t have anythin in its site-package.

The deb seems to do evil magic stuff…

Edit : ok, looked a bit deeper, both python2.6 and python2.5 have the panda3D.pth, with the same content, but I still doesn’t work.

#4

It is only supposed to work with Python 2.6. They renamed site-packages to dist-packages there. I suggest removing the panda3d.pth from the python2.5 site-packages to remove confusion.

Panda’s jaunty deb is compiled against python 2.6, which is the default on ubuntu jaunty, so I actually didn’t expect it to work at all in 2.5.

If you still want to use Python 2.5 instead of 2.6, install the Intrepid build instead.

#5

ok, I understand but in the future could you add the expected python version in the name of the deb ?

This needs to be more explicit.

#6

Actually, it suprises me that you were able to install python 2.5 on Jaunty at all.

I marked python2.6 as dependency of the deb - and you are supposed to use “python” to run Panda stuff, not “python2.5”.
