Embedding Python3 in C++ with CMake

This project includes several examples of how to embed Python in C++ with CMake. Please be sure that this project was only built and tested on MacOS.

Environments

• MacOS 12.0.1
• Miniconda 4.12.0
• CMake 3.22.3

How to build

Miniconda or Anaconda is required.

(base)% conda create -n ep python=3  
(base)% conda activate ep  
(ep)% pip install numpy  

# before installing gcc, Xcode was already installed which was not sure to affect compilation of the source code. 
(ep)% brew install git cmake gcc

(ep)% git clone https://github.com/supertigim/EmbeddingPython3inCppwithCMake.git
(ep)% cd EmbeddingPython3inCppwithCMake

(ep)% sh ./build_all.sh

# python related logs when running cmake 
Python_FOUND:TRUE
Python_VERSION:3.10.4
Python_Development_FOUND:TRUE
Python_LIBRARIES:/usr/local/Caskroom/miniconda/base/envs/ep/lib/libpython3.10.dylib
Python_INCLUDE_DIRS:/usr/local/Caskroom/miniconda/base/envs/ep/include/python3.10

Then, go to ./build directory and run embedding-python-ex1 ~ 8
