Thanks  Chris,

I think I figured it out that when build python on Linux, we need to
enable-shared.

Thanks again,

By "calling Python from C", do you mean what the docs call "embedding"?

https://docs.python.org/3/extending/embedding.html

I would recommend following the tutorial there, if you haven't
already. If you have, and the tutorial code doesn't work for you, post
your code and what you did, and we'll try to help with that.
