Hi
I’v been using Panda3d for weeks on my linux x64 but today it stops working!?

$ python ./main.py 
Known pipe types:
(all display modules loaded.)

Your Config.prc file must name at least one valid panda display
library via load-display or aux-display.

I’ve used these commands to build and install panda3d:

$ python2.7 makepanda/makepanda.py --everything --rtdist --distributor seifi --host http://127.0.0.1:9449/runtime/
$ sudo python2.7 ./makepanda/installpanda.py --outputdir=./built_seifi --prefix=/usr
$ sudo python2.7 ./makepanda/installpanda.py --outputdir=./built_seifi_rt --prefix=/usr --runtime

The /etc/Config.prc exists.

Please don’t use installpanda on the output of an rtdist build. I don’t know what happens when you try it, but it can’t be good. It might be related to the problem, ie. some library conflict of libpandagl.so.

So you mean i should built it without --rtdist and then install that?
I’ll give it a try.

Um, that depends on whether you are trying to build an rtdist build or an SDK build. An rtdist is something you upload to a runtime host like runtime.panda3d.org/ for production use in the .p3d ecosystem - an SDK is something you install on your local computer in order to do Panda3D development.
