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:

Code: Select all: 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> from libpandaModules import * File "/Developer/Panda3D/lib/pandac/libpandaModules.py", line 2, in <module> Dtool_PreloadDLL("libpanda") File "/Developer/Panda3D/lib/pandac/extension_native_helpers.py", line 79, in Dtool_PreloadDLL imp.load_dynamic(module, pathname) ImportError: dlopen(/Developer/Panda3D/lib/libpanda.dylib, 2): Library not loaded: librfftw.2.0.7.dylib Referenced from: /Developer/Panda3D/lib/libpanda.dylib Reason: image not found

Running

Code: Select all: 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:

Code: Select all: Attempt to register type Namable more than once! Attempt to register type TextEncoder more than once! Attempt to register type VirtualFileComposite more than once!

Abort trap

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

Thanks,
Dustin

Ugh. Looking at the build log for this build:

Code: Select all: 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"?

by **rdb** » Wed Jun 23, 2010 5:37 am

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:

Code: Select all: 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/)?

by **dsmith** » Thu Jun 24, 2010 3:48 pm

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

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:

Code: Select all: lipo -info /Developer/Panda3D/lib/librfftw.2.0.7.dylib Architectures in the fat file: /Developer/Panda3D/lib/librfftw.2.0.7.dylib are: ppc i386 lipo -info /Developer/Panda3D/lib/libpanda.1.7.dylib Architectures in the fat file: /Developer/Panda3D/lib/libpanda.1.7.dylib are: i386 ppc7400 pview dyld: Library not loaded: @executable_path/../Library/Frameworks/Cg.framework/Cg Referenced from: /Developer/Panda3D/lib/libpanda.1.7.dylib Reason: image not found Trace/BPT trap

Ditto pview

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

by **alia** » Wed Aug 04, 2010 1:36 am

So aparently i missed this:

http://developer.nvidia.com/object/cg_download.html

fixed!
