OSX SDK Panda3D-2010.06.21-190 Problems

dsmith · June 21, 2010, 4:39pm

I’m having some problems running Panda using the latest SDK snapshot Panda3D-2010.06.21-190.dmg on OSX 10.5 32-bit intel.

The first issue I run into is a missing library:

Traceback (most recent call last):
  File "main.py", line 10, in <module>
    from pandac.PandaModules import loadPrcFileData
  File "/Developer/Panda3D/lib/pandac/PandaModules.py", line 8, in <module>

  Referenced from: /Developer/Panda3D/lib/libpanda.dylib

Running

otool -L /Developer/Panda3D/lib/libpanda.dylib

shows no path for the linked FFW library.

My attempt to workaround this was to copy the librfftw.2.0.7.dylib file to my working directory. This causes another problem:

I’m currently building from source, so I’ll see if I can get around this.

Thanks,

Ugh. Looking at the build log for this build:

install_name_tool -change librfftw.2.0.7.dylib /Developer/Panda3D/lib/librfftw.2.0.7.dylib dstroot/base/Developer/Panda3D/lib/libpanda.dylib
install_name_tool: changing install names can't be redone for: dstroot/base/Developer/Panda3D/lib/libpanda.dylib (for architecture ppc7400) because larger updated load commands do not fit (the program must be relinked)
Process exited with exit status 1 and signal code 0

Looking at the output for “lipo -info” for this library, it seems that libpanda.dylib has architecture ppc7400 while librfftw.dylib has architecture ppc.

I’m going to try rolling out a build against the Tiger SDK, to see if that fixes things. I’ll let you know when it’s finished, so you can try.

As for your other issue - I have no idea. It appears that two copies of Panda3D are loaded into memory. Does it even occur if you simply try to run “pview”?

rdb · June 23, 2010, 10:37am

Never mind, I was entirely wrong. The issue turned out to be something completely different.

Can you try installing the latest buildbot release? It should fix the issue.

I downloaded Panda3D-2010.06.24-197.dmg and the first problem is gone!, but I’m still running into the “Attempt to register … more than once” errors, followed by a crashing of Python with:

Assertion failed: (child_node != (TypeRegistryNode *)NULL && base_node != (TypeRegistryNode *)NULL), function is_derived_from, file dtool/src/dtoolbase/typeRegistry.cxx, line 307.

Does that issue happen with pview, too?

Also, are you sure you don’t have multiple versions of Panda3D installed at the same time, like 1.6.x (in /Applications/Panda3D/) and 1.7.x (in /Developer/Panda3D/)?

dsmith · June 24, 2010, 8:48pm

No, pview works. I removed all Panda installs and the ~/Library/Cache/Panda3D directory. Could it be loading from the same install multiple times?

Thanks,
Dustin

rdb · July 28, 2010, 8:24am

I just checked in a fix, and I think the latest buildbot release fixes this.

Oh, very good! Rdb rocks!

Heyas,

Just grabbed the 1.7.0 build and the 2010.08.03-238.dmg and both have this issue still:

Did you install the required NVIDIA Cg Toolkit from their website?

alia · August 4, 2010, 6:36am

So aparently i missed this:

developer.nvidia.com/object/cg_download.html

fixed!
