Problems starting Panda3d on Mac with Snow Leopard

[Oman10]

Hello to you all.

Few years back I have used panda3d in combination with python on a windows machine.

I just installed panda3d (and the NVIDIA CG toolkit) again yesterday, but now on my macbook pro with brand new Snow Leopard. But when I walked through the manual (I have to refresh) first thing goes wrong while starting up my test script containing only:

import direct.directbase.DirectStart
run()

The error message I receive is the following:

DirectStart: Starting the game.
:display(warning): Unable to load: dlopen(/Applications/Panda3D/1.6.2/lib/libpandagl.dylib, 6): Library not loaded: /usr/X11/lib/libOSMesa.4.dylib

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

So either the Panda3d path variables are not set correctly (I watched the Config.prc file, but have no clue what to change)

Uncomment one of the following lines to choose whether you should

run using OpenGL or DirectX rendering.

load-display pandagl
#load-display pandadx9
#load-display pandadx8

(Off course, I tried all, but with no other result) OR the NVIDIA toolkit is not working properly on my Snow Leopard installation.

Can somebody help me with changing settings(?) so Panda3d will run on my mac?

It’s a known issue, and will be resolved in the next version of Panda3D.

To highlight the post in that thread that should help you out:

@Manne

Symlinking worked great.

So, for thoose of you who dont know how. Here is a workaround to get Panda to work on Snow Leopard.

Download the Cg installation (Cg-2.2.0006) from nvidia. Rightclick on the installer and select show package contents. In Contents->Resources->Installer Items there is a file: NVIDIA_Cg.tgz. Copy this to your desktop. Doubleclick on it to unpack.
Now, copy the Cg.Framework in NVIDIA_Cg->Library->Frameworks to /Libraray/Frameworks.

Open a terminal and run this.
sudo ln -s /usr/X11/lib/libOSMesa.7.dylib /usr/X11/lib/libOSMesa.4.dylib

Now Panda should work.
