import python module from C++ code

[Arthur Mc Coy]

Hi all,


I have a C++ application. I have a .cpp file which is not a main
program, but a class where I want to call python script
(doSomething.py file).

I'm using embed python like in a tutorial here:
http://www.codeproject.com/KB/cpp/embedpython_1.aspx

But the tutorial is bad. It does not explain howto create python
module which they call in their example. doSomething.py file contains
two classes, one of them I use externally (its functions).

So I need to PyImport_Import(py_module) by name of this py file, but
when I try to do that it fails. Please, give me some examples.


If needed, I can attach my code as well.
Thank you, waiting for anybody's response!
Be happy.

The problem is "how to write python module under SWIG for C++
application"

Nor SWIG documentation neither embeding python documentation does not
answer to this.


If you can help, please, share your idea.

Still need the answer to the question: " howto embed given python file
(which contains python class and its members) into the c++
application ? "

I have to pass the arguments from c++ to python and back so I need to
do conversions. They are ok. Fails PyImport_Import(my_module) call
saying "No module called mymodule". Then I need to create a mymodule
based on given python file (its name mymodule.py). Can it be achieved
using SWIG ?

I'm very curious and looking for some feedback if possible
Be happy.

There is no straight way of embedding a Python module into a c++
application.

You will have to embed the python interpreter, and command it to load
the module in question and execute the code you want.

Did you configure the module search path properly?
