I trying to make minimal part of Python to work as part (static library)

  • 0

I trying to make minimal part of Python to work as part (static library) of my iOS application for internal scripting. I used configure under Mac OS X(10.7) and it was successful. Then I got compilable and linkable XCode project very fast.
The problem is, when I trying to use Python by

Py_NoSiteFlag=1;
Py_Initialize();

it fails with error “Fatal Python error: exceptions bootstrapping error.” inside _PyExc_Init().
I tried to debug it, but unfortunately I cant understand why it fails. May be bacause I noob in Python source, but anyway, I need to port it. Tried 2.7.3, or 3.2.3, it was the same result as above. Any solution or hint will be very helpful.

    Two thoughts:

    1. The error you’re getting is from a failing to import builtins module.

      From http://hg.python.org/releasing/3.2.3/file/86d1421a552c/Objects/exceptions.c

      2040     bltinmod = PyImport_ImportModule("builtins");   
2041     if (bltinmod == NULL)
2042         Py_FatalError("exceptions bootstrapping error.");

      You can follow the code up from there, and there are lots of reasons why
      this import could fail. If you want to know what’s actually wrong, you’ll
      need to step through it.

    2. Or, you could check this out:
