Does it help if you call this before trying maya2egg:

export MAIN_DIR=/usr/bin

Perhaps Panda’s Python is interfering with Maya’s Python? I’ve seen this happen before, and it’s a vexing problem. The only truly reliable way I’ve found to avoid it is to build a version of Panda without Python support, and use that version to generate maya2egg.

Are you running the pre-built version of Panda downloaded from this site, or did you build your own?

That’s what I was guessing. Since we call into Python for the MAIN_DIR check in ExecutionEnvironment, and it crashes on that PySys_GetObject call (that means it passed the Py_IsInitialized() call), that’s where it usually goes wrong first.

I notice that we don’t link pystub into the Maya converters on Linux, while we do that on Windows. Maybe that could be a problem?

I don’t think we ship the prebuilt Linux builds with Maya support.

Regardless, try the MAIN_DIR hack, that should disable that code in ExecutionEnvironment. Maybe that’ll fix it, but maybe it’ll crash somewhere else. We’ll see.

yes it is helped
thanks all

i build panda but i had some problems so i copied maya2egg
and install pre-built panda after i copy maya2egg back :slight_smile:

That might be why - in some cases it seems that maya2egg is happier if used with the same build it came from.
