使用Boost.Python创建的Python模块将不会导入

Question

I have a big C++ module with Python 3 bindings using Boost.Python, that I compile to a .so file using CMake on macOS.

When I try to import it in the REPL, everything seems to work fine:

>>>import myModule
>>>

However, as soon as I run the import statement, the famous rocket icon of Python shows up in the Dock and stays there jumping for some minutes and stops after. Obviously then, I cannot access any of the functions defined in my module, so the import looks fine but doesn't actually do anything.

I tried looking in the Console and saw that whenever I import myModule , I get two launchservicesd[83]: SecTaskLoadEntitlements failed error=22 . It brought me to this and that related questions but I can't find what the exact problem is.

The C++ module is huge so I just can't look at the code and find the problem, thus I'm asking for any hints about at least how to debug that problem.

Answer 1

I can suggest the following steps:

• Try to import that module though local python session. So, run interactive python interpreter, and 'import myModule'.

If bad, try to check:

• are python version, with which myMoudle was linked with, is similiar to used interpreter
• check that build architectires are the same
• check that you can load even simple boost.python example module

If ok, check that you have correctly set up module search path in your python code.
