I also have to mention that in general compiling Panda3D undere Linux is really painfull… I have arch linux and i tried to install Panda3D from AUR, and NO ONE PKGBUILD made package correctly… I think it’s not only fault of maintainers.

Use latest CVS Panda, this has already been fixed (we were using functions in ffmpeg that have since been deprecated). I think there’s a pkgbuild out there for the CVS version of Panda.

Yes, i was trying this PKGBUILD and I got:

It apparently depends on libRocket but you don’t have it installed.

Yes, i do have installed this from AUR (librocket-cvs)
