Problems with sample programs

Scripting Issues

Hi guys,

I just compiled and installed 1.7.1.
Then I tried to start the sample programs to check whether it is working. But every sample gives me this error:

[erik@erik-laptop Asteroids]$ python Tut-Asteroids.py

Do you have any other versions of Panda already installed? It looks to me like you’re inadvertently linking with the wrong version. Try uninstalling any other versions.

Thanks for reply.

You were right. There were still parts of another panda3d installation on the disk.
Now it should be all right. But i get this error:

ImportError: libp3dtool.so.0.0: cannot open shared object file: No such file or directory

Any ideas?

Well, that means that libp3dtool.so.0.0 (or perhaps some .so file that libp3dtool depends on) is not on your LD_LIBRARY_PATH, or your system ldconfig path.

Which points to a problem with installation. What steps did you follow to compile and install Panda? The best way is usually to run makepanda with the --installer option, then run the generated installer.

Hi,

i ran makepanda.py --everything and installpanda.py frome the makepanda directory according to the makefile of pande3d-1.6.2

The 0.0 part sounds like a serious problem with the compilation. Perhaps header files have conflicted.

So i did not make a mistake during installation?
It seems to be more a source related problem as far i understood, right?

Thanks for clarify
