Problems Panda3D install on mac OS X 10.9

Installation
1

Hi all,

I am trying to install Panda3D on Mac OS X 10.9 from the Panda3D-1.9.0.dmg file.
I have python 2.7 (64 bits).
Here is the error I have when running the example “Asteroid” with

ppython main.py
DirectStart: Starting the game.
Traceback (most recent call last):
  File "main.py", line 13, in <module>
    import direct.directbase.DirectStart
  File "/Developer/Panda3D/direct/directbase/DirectStart.py", line 3, in <module>

  Referenced from: /Developer/Panda3D/lib/libpanda.1.9.dylib
  Reason: image not found

I have tried a lot of things found on this forum (and many other) but nothing works…
Someone could help ?
Thank you very much,

Cheers

Install the NVIDIA Cg Toolkit from the site:

I have installed the NVIDIA Cg Toolkit. Here is the error I have when running the “Asteroid” Example:

It seems that I have a problem with my path, but don’t know how to solve that.
I tried:

>>> from pandac.PandaModules import * 
>>> print getPluginPath() 
<auto>
>>> print repr(getPluginPath())
<auto>
>>> print ConfigPageManager.getGlobalPtr().getSearchPath()
/usr/local/p1/etc

But /usr/local/p1/etc/ does not exists !!!

Thank you very much !!!
It works !

Hi all,

Sorry to be here again !
My problem was solved. I can now run all the Panda3D examples.
However, I am using a python code importing numpy which create a panda3D interface.
My problem now is that when I run my code with ppython I have the following error:

ImportError: No module named numpy

And when I run my code with python, I have a seg fault due to

from direct.showbase.ShowBase import ShowBase

:

I have copied the Panda3D.pth file in /Library/Python/2.7/site-packages/

I don’t know where is the problem.

Thank you very much for your help.

Just one precision:

I also copied the Panda3D.pth file in :
/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/

where all the python lib are

You have to install numpy in the same Python installation where Panda is installed, ie. into the system Python 2.7 installation.

I am trying to install panda3D from source as you proposed with python 2.7.
I always have an error when I run

python makepanda/makepanda.py --everything --installer --no-ffmpeg --no-vrpn --no-rocket --no-opencv --no-gles --no-gles2 --no-egl

Here is the error:

I am not sure to use the right python version… I have only one version of python 2.7 by default (2.7.6).

I also tried to reinstall the dmg (1.9.0) you built with python2.7, 64 bits. But still have the same seg fault when running my code…

Hi rdb,

I am sorry to be here again !
I installed numpy into the system Python 2.7 installation, removing the macports ones before.
Panda3D is working (i.e. the examples are working).
But still have a lot of troubles with my python code because it needs a lot of python libraries and opencv, etc…
and the installation of all these libraries is very long and complicated.
As example, I used to install opencv using macports, and now I have some errors when installing it manually.
I think I will drop panda3D on my mac. I have it working on ubuntu…

Thanks again for your help
Cheers

You can use easy_install or pip to install those third-party libraries easily.

13

Yes. I should install all the libraries I need using pip or easy_install. I have no time to do that now. I will see later, maybe next week… Thank you very much for your help.

Cheers

I am having a similar issue when trying to build Panda3D from source on mac os x 10.9. I need to do this in order to have a newer build than the .dmg you provided. Do you have any ideas what may be causing this build error. I checked out the latest version from the repository about 1 week ago. Thank you!

I tried to follow this blog post’s advice in order to have a 64 bit installation. jesshamrick.com/2013/09/26/i … 27-on-osx/

I advise you to grab the latest development source of Panda3D, I believe it has this issue fixed.
