Pb with Scene Editor and Tcl/Tk

Compiling or Editing the Panda Source

Hello all:

I have successfully compiled Panda3D in Suse 9.3, but when I run the Scene

Editor, it crashes and produces the following error.

DirectStart: Starting the game.
enumerate is already present in builtin
Warning: DirectNotify: category ‘Interval’ already exists

glxGraphicsPipe
(all display modules loaded.)
Warning: DirectNotify: category ‘ForceGroup’ already exists

Any idea?

Thanks in advance

I suspect you are experiencing the problem discussed here:
https://discourse.panda3d.org/viewtopic.php?t=310

And here:
https://discourse.panda3d.org/viewtopic.php?p=1936

And also reported here:
https://discourse.panda3d.org/viewtopic.php?t=613

In short, set the following environment variable:


export LC_NUMERIC=C

Hello:

  This works. The scene editor starts but when I click on the

main window (black one), it crashes and produces an error:

File “/home/ajfg/SceneEditor/seSelection.py”, line 457, in collideWithWidget
mask.setWord(0x80000000)
File “BitMask32”, line 254, in setWord
OverflowError: long int to large to convert to int

Any idea?

You must be using Python 2.4, which is not yet officially supported by Panda3D (it will be officially supported in the Panda3D 1.1 release).

In Python 2.4, some of the rules for large unsigned integers changed, so some of the Panda code has to be modified to account for the change.

Try modifying the offending line 457 in seSelection.py from the following:


mask.setWord(0x80000000)

To this:


mask.setBit(31)

Hello,

That works. Thank you very much
