cmake_example for pybind11

An example pybind11 module built with a CMake-based build system. This is useful for C++ codebases that have an existing CMake project structure.

Prerequisites

On Unix (Linux, OS X)

• A compiler with C++11 support
• CMake >= 2.8.12

On Windows

• Visual Studio 2015 (required for all Python versions, see notes below)
• CMake >= 3.1

Installation

Just clone this repository and pip install. Note the --recursive option which is needed for the pybind11 submodule:

git clone --recursive https://github.com/pybind/cmake_example.git
pip install ./cmake_example

With the setup.py file included in this example, the pip install command will invoke CMake and build the pybind11 module as specified in CMakeLists.txt.

Special notes for Windows

Compiler requirements

Pybind11 requires a C++11 compliant compiler, i.e Visual Studio 2015 on Windows. This applies to all Python versions, including 2.7. Unlike regular C extension modules, it's perfectly fine to compile a pybind11 module with a VS version newer than the target Python's VS version. See the FAQ for more details.

Runtime requirements

The Visual C++ 2015 redistributable packages are a runtime requirement for this project. It can be found here. If you use the Anaconda Python distribution, you can add vs2015_runtime as a platform-dependent runtime requirement for you package: see the conda.recipe/meta.yaml file in this example.

License

Pybind11 is provided under a BSD-style license that can be found in the LICENSE file. By using, distributing, or contributing to this project, you agree to the terms and conditions of this license.
