• boost: example for Boost.Python
• pybind11: example for pybind11
• nanobind: example for nanobind

Boost.Python

It is assumed that the Boost.Python has been compiled and installed into some place by using e.g., MateriApps Installer, etc, and BOOST_ROOT environment variable has been set properly.

Pybind11

Pybind11 is a header-only library. It is automatically downloaded.

Nanobind

Nanobind11 is automatically downloaded.

How to build samples and run tests

cd /somewhere/pycxx
cmake -B build
cmake --build build
cmake --build build --target test

Options to cmake

• BOOST_ROOT: specify the place in which the Boost Library is installed

  ex) -DBOOST_ROOT=$HOME/boost/

• CMAKE_CXX_COMPILER: spacify C++ compiler

  ex) -DCMAKE_CXX_COMPILER=g++

• PYTHON_EXECUTABLE: specify Python interpreter

  ex) -DPYTHON_EXECUTABLE=/opt/local/bin/python3
