win32 python as a dll?

[Scott Wolford]

Here's the smallest case that gives me problems:
#include "Python.h"
#include <stdio.h>
int main(int argc, char **argv)
{
//  return Py_Main(argc, argv);
  FILE *file = fopen(argv[0], "rt");
  PyRun_AnyFile(file, argv[0]);
}

I just modified python.c to run the script like I do in my application. I
get the following error:
Fatal Python error: PyThreadState_Get: no current thread

The Py_Main line works fine. Any takers?

Thanks in advance,
Scott

Thanks for doing so.

I knew that; brain fart. I've written my own makefile for python and my
application works fine when I build it myself.

I agree, but in the *normal* fashion.

Nope, I use msvcrt and msvcrtd. You say Multithreaded *DLL* so that's what
you mean (and not libcmt.lib), right?
