导入 Python 并在 C++ 中扩展

Question

SOLVED: turns out I had a messed up path var in link script

I have a problem concerning executing embedded python code in C++. I have a C++ program that dynamically executes a regular Python file using:

...
PyObject_CallObject(func, args);
...

Everything works as expected when I use plain function in the injected python scripts. But when I want to import some extension in the python script:

import "libraryname"
... 

, I get the following runtime error:

ImportError: No module named "libraryname"...

The python code works using the regular interpreter but not ones it's injected in C++. I've tried explicitly loading the python library folder both in the PATH var and in the linker without any success.

(I'm using Linux/Debian.)

Answer 1

Imports in Python don't use quotes around the name.

import libraryname

Also, inject the module into sys.modules first.
