PyRun_SimpleFile() crashes

[lixinyi.23]

my code:
main.cpp
#include <Python.h>

int main(int argc, char **argv)
{
Py_Initialize();

FILE *file_1 = fopen("a2l_reader.py","r+");
PyRun_SimpleFile(file_1,"a2l_reader.py");

Py_Finalize();
}

compile under windows using MinGW:
g++ main.cpp libpython25.a -o a

no error was found. But when I run a.exe the program just crashes.

What should I do?

PyRun_File and PyRun_SimpleFile would just crash my application.
but PyRun_SimpleString works fine.

But why???

Run it under gdb (which should have come with MinGW).

Check that you actually opened the file, ie file_1 != 0.

This might be relevant

There's a workaround.

filename = "Entire path of the python file";
PyObject* PyFileObject = PyFile_FromString(filename, "r");
PyRun_SimpleFile(PyFile_AsFile(PyFileObject), filename);
// decref PyFileObject

Just to follow up-- The links say that the crash comes from opening a
file with two different versions of a library. Would it be possible
to get an API entry point to the version the build uses?

It does use the 'fopen' function by name, but not the same version.
And creating the entire object just to get its f_fp field is really
long.

Wow this one works fine for me.
Thank you!
