This repo contains an example of how to create Python bindings for a C++ library. The Python package is contained in the code/ directory, with the C++ library nested in code/bindings/cpp. The package is built using scikit-build-score to stitch together Python and CMake for the build. The C++ library implements saxpy (scalar multiplication followed by vector addition) using Thrust. The Python package exposes a simple binding that allows saxpy to be called on a pair of CuPy arrays.

This repo contains a docker-compose configuration and a Dockerfile that can be used to build the necessary container. It also contains a pair of (shell and Python) scripts that may be used to run the example. Assuming docker-compose is installed, the example may be run as follows:

# Clone the project
git clone --recurse-submodules https://github.com/vyasr/cpp_bindings_demo
cd cpp_bindings_demo

# Build and launch the Docker container
docker-compose build
docker-compose run cpp_bindings_demo

# Inside the container:
./demo.sh
