Embeddor Woes...

[Preston H]

Hello, someone may have tackled this problem before but I have
searched the google newsgroups up and down and I can't find anything
on this. I am trying to write an embedded python program in C++ that
will go out and execute python language in a script.

I am using Visual C++ .NET, and I do have Multithreaded DLL(/MD)
turned on for the Runtime Library, I have the Python 2.2 installed and
their include and libs directories are set. Also, I have Visual C++
..NET set to release version, mainly because I cannot find
python22_d.dll anywhere.

This is the error that I get when I successfully compile this program
and try to run it at a dos prompt...

The instruction at "0x77f85c41" referenced memory at "0x00000010".
The memory could not be "written".

This is the source code that I am trying to test...

#include "python.h"
#include <stdio.h>

int main(int argc, char* argv[])
{
char *filename = "test.py";

FILE *OurFile = fopen(filename, "r+");

Py_Initialize();

PyRun_SimpleFile(OurFile, "test.py");

Py_Finalize();

return 0;
}

Like I said earlier, the program compiles without any hitches. Any
help on this is appreciated very much!

Have you tried to use embedding.cpp from the boost.python examples? It
will show if your configuration is working OK; if it is, the problem is
obviously in your program. At first sight I'd say that your test.py
can't be found - did you set the right working directories?

cheers,

PyRun_SimpleFile doesn't work for me too.

As a workaround I suggest to replace it with:
PyRun_SimpleString("execfile('test.py')");

That did it... I wonder why PyRun_SimpleFile or PyRun_File won't
work? Do I have to recompile the python source under MSVC++.NET?

PyRun_SimpleFile doesn't work for me too.

As a workaround I suggest to replace it with:
PyRun_SimpleString("execfile('test.py')");
