[Pythonmac-SIG] Python embedding in LabVIEW on Mac?

[Marcus H. Mendenhall]

Hi, All.

I recently came across a need to access Python code from inside of 
LabVIEW to do some data analysis.  Under LabVIEW 6i for Windows, 
calling Py_Initialize works fine.  Using LabVIEW 5.0.1 under MacOS 
8.x and 9.x (OK, I haven't updated my LabVIEW install yet to anything 
approaching current... anyone know if it is OK under LV6 for Mac?) 
calling Py_Initialize results in LabVIEW quietly exiting.  It appears 
that ExitToShell() is called, since there is no sign of of a crash.

Under what conditions does Py_Initialize fail in such a way? I have 
tried starting LabVIEW from various directories, including the one 
containing PythonCore, in case paths are bad resulting in inability 
to find resources.  If have also called Py_SetProgrameName before 
PyInitialize, with the full path to PythonCore as the name, just in 
case that would help.  No luck.

Since it is likely a quite painful process to follow through the 
innards of LabVIEW with a debugger, it seems more likely to be 
fixable by following through the Python startup.

Thanks for any ideas anyone might have, before I waste a lot of time 
poking around my self rather blindly.
