An example project built with pybind11.

Installation

On Unix (Linux, OS X)

• clone this repository
• pip install ./python_example

On Windows (Requires Visual Studio 2015)

• For Python 3.5+:

  • clone this repository
  • pip install ./python_example

• For Python 2.7:

  Pybind11 requires a C++11 compliant compiler (i.e. Visual Studio 2015 on Windows). Running a regular pip install command will detect the version of the compiler used to build Python and attempt to build the extension with it. We must force the use of Visual Studio 2015.

  • clone this repository
  • "%VS140COMNTOOLS%\..\..\VC\vcvarsall.bat" x64
  • set DISTUTILS_USE_SDK=1
  • set MSSdk=1
  • pip install ./python_example

  Note that this requires the user building python_example to have registry edition rights on the machine, to be able to run the vcvarsall.bat script.

CI Examples

There are examples for CI in .github/workflows. A simple way to produces binary "wheels" for all platforms is illustrated in the "wheels.yml" file, using cibuildwheel. You can also see a basic recipe for building and testing in pip.yml, and conda.yml has an example of a conda recipe build.

Windows Python 2.7 runtime requirements

On Windows, the Visual C++ 2015 redistributable packages are a runtime requirement for this project if you build for Python 2.7 (newer versions of Python include this redistributable). It can be found here.

Building the documentation

Documentation for the example project is generated using Sphinx. Sphinx has the ability to automatically inspect the signatures and documentation strings in the extension module to generate beautiful documentation in a variety formats. The following command generates HTML-based reference documentation; for other formats please refer to the Sphinx manual:

• cd python_example/docs
• make html
