[Pythonmac-SIG] Python dieing outside project builder

[Matthew Smith]

Hello,

Thanks for the help!

I'm calling:

Py_SetProgramName("My App");
Py_Initialize();

I then make python aware of some functions in the app.

Then:

VBALLOW_PYTHON = !PyRun_SimpleString("execfile(\"autoexec.py\")\n");

if (!VBALLOW_PYTHON)
   printf("autoexec didn't execute!\n");

Where VBALLOW_PYTHON is a bool.

I'll give printing the working directory, or setting the Py_VerboseFlag to
1, though my app seems to pick up other files in the same directory ok...

Also, I'm quite the python novice, but it seems that I am doing a simaler
thing to yours, Alex...

Thanks again,

Matt
