ModuleNotFoundError: No module named 'example' while running sample add program

[karimkhanp]

I want to integrate C++ with python. I closely followed the documentation here - https://pybind11.readthedocs.io/en/latest/basics.html

My OS - Mac

Steps to reproduce the error -

$ git clone https://github.com/pybind/pybind11.git
$ cd pybind11
$ mkdir build
$ cd build
$ cmake --version
cmake version 3.25.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).
$ cmake ..
$ make check -j 4
$ cd .. 
(put example.cpp in pybind11 directory)
$ c++ -O3 -Wall -shared -std=c++11 -undefined dynamic_lookup $(python3 -m pybind11 --includes) example.cpp -o example$(python3-config --extension-suffix)
$ python
$ >>> import example
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'example'

additional info

(vi_ai) karimkhan@192 pybind11 % whereis python3
python3: /usr/bin/python3 /usr/local/share/man/man1/python3.1
(vi_ai) karimkhan@192 pybind11 % whereis python 
python: /Users/karimkhan/Documents/virtualenv_dir/vi_ai/bin/python

So I tried with this command

c++ -O3 -Wall -shared -std=c++11 -undefined dynamic_lookup $(python -m pybind11 --includes) example.cpp -o example$(python3-config --extension-suffix)

But still it gives same error.

I am currently using my virtualenv vi_ai. And while compilation, it usage same virtualenv path so everything looks fine as far as python version concern I believe.

When I do

whereis python3-config
python3-config: /usr/local/bin/python3-config

python3-config path appears from outside virtualenv path. I don't see python3-config in virtualenv site packages.

Any recommendation?

I tried same steps on Linux as well but there also getting the same error.
