I needed a 32 bit .deb of Panda 3D 1.8.0 for Ubuntu 12.04, so I built one using the instructions from PeteX.
The only thing different is that I added the fmod library as well.
I uploaded the .deb onto my dropbox if anyone wants to use it, I’ve tested it on Ubuntu 12.04 using the Sandybridge graphics, and everything works fine.
