未找到来自导入的 swig 包装模块的功能

Question

I want to create several Python modules from SWIG-wrapped C++ classes. The problem is that modules cannot import each other.

here is A_module.i file

%module A_module
%inline
%{
    void foo(){}
%}

it compiles without problem, thus in .py script I can do something like this:

import A_module
A_module.foo()

Now I want to create B_module that import A_module and calls foo. Here is B_module.i file

%module B_module
%import A_module.i

When I do something like this in .py

import B_module
B_module.foo()

It gives an error syaing module has no attribute foo.

The solution I've found is to use %include instead of import, but it creates same foo function in both modules, which I would like to avoid

Answer 1

That .i %import is a Python import , so the foo you're looking for lives as B_module.A_module.foo . You can use Python code explicitly to import and copy parts of A_module into B_module. For example, have as B_module.i :

%module B_module

%pythoncode %{
import A_module
foo = A_module.foo
del A_module
%}
