For an overview of Python packaging including compiled packaging with a pybind11
|

example, along with a cookiecutter that includes several pybind11 options, see
|
||||
the `Scientific Python Development Guide`_.

Modules with CMake
|
||||
==================
|
||||
|
||||
A Python extension module can be created with just a few lines of code:
|
||||
|
||||
.. code-block:: cmake
|
||||
|
||||
cmake_minimum_required(VERSION 3.15...3.29)
|
||||
project(example LANGUAGES CXX)
|
||||
|
||||
set(PYBIND11_FINDPYTHON ON)
|
||||
find_package(pybind11 CONFIG REQUIRED)
|
||||
|
||||
pybind11_add_module(example example.cpp)
|
||||
install(TARGET example DESTINATION .)
|
||||
|
||||
(You use the ``add_subdirectory`` instead, see the example in :ref:`cmake`.) In
|
||||
this example, the code is located in a file named :file:`example.cpp`. Either
|
||||
method will import the pybind11 project which provides the
|
||||
``pybind11_add_module`` function. It will take care of all the details needed
|
||||
to build a Python extension module on any platform.
|
||||
|
||||
To build with pip, build, cibuildwheel, uv, or other Python tools, you can
|
||||
add a ``pyproject.toml`` file like this:
|
||||
|
||||
.. code-block:: toml
|
||||
|
||||
[build-system]
|
||||
requires = ["scikit-build-core", "pybind11"]
|
||||
build-backend = "scikit_build_core.build"
|
||||
|
||||
[project]
|
||||
name = "example"
|
||||
version = "0.1.0"
|
||||
|
||||
You don't need setuptools files like ``MANIFEST.in``, ``setup.py``, or
|
||||
``setup.cfg``, as this is not setuptools. See `scikit-build-core`_ for details.
|
||||
For projects you plan to upload to PyPI, be sure to fill out the ``[project]``
|
||||
table with other important metadata as well (see `Writing pyproject.toml`_).
|
||||
|
||||
A working sample project can be found in the [scikit_build_example]_
|
||||
repository. An older and harder-to-maintain method is in [cmake_example]_. More
|
||||
details about our cmake support can be found below in :ref:`cmake`.

Modules with meson-python
|
||||
=========================
|
||||
|
||||
You can also build a package with `Meson`_ using `meson-python`_, if you prefer
|
||||
that. Your ``meson.build`` file would look something like this:
|
||||
|
||||
.. _meson-example:
|
||||
|
||||
.. code-block:: meson
|
||||
|
||||
project(
|
||||
'example',
|
||||
'cpp',
|
||||
version: '0.1.0',
|
||||
default_options: [
|
||||
'cpp_std=c++11',
|
||||
],
|
||||
)
|
||||
|
||||
py = import('python').find_installation(pure: false)
|
||||
pybind11_dep = dependency('pybind11')
|
||||
|
||||
py.extension_module('example',
|
||||
'example.cpp',
|
||||
install: true,
|
||||
dependencies : [pybind11_dep],
|
||||
)
|
||||
|
||||
|
||||
And you would need a ``pyproject.toml`` file like this:
|
||||
|
||||
.. code-block:: toml
|
||||
|
||||
[build-system]
|
||||
requires = ["meson-python", "pybind11"]
|
||||
build-backend = "mesonpy"
|
||||
|
||||
Meson-python *requires* your project to be in git (or mercurial) as it uses it
|
||||
for the SDist creation. For projects you plan to upload to PyPI, be sure to fill out the
|
||||
``[project]`` table as well (see `Writing pyproject.toml`_).

You also need a ``MANIFEST.in`` file to include all relevant files so that you

If you use `PEP 518's <https://www.python.org/dev/peps/pep-0518/>`_

``pyproject.toml`` file, you can ensure that ``pybind11`` is available during
|
||||
the compilation of your project. When this file exists, Pip will make a new
|
||||
virtual environment, download just the packages listed here in ``requires=``,
|
||||
and build a wheel (binary Python package). It will then throw away the
|
||||
environment, and install your wheel.

.. code-block:: toml

.. note::

The main drawback to this method is that a `PEP 517`_ compliant build tool,
|
||||
such as Pip 10+, is required for this approach to work; older versions of
|
||||
Pip completely ignore this file. If you distribute binaries (called wheels
|
||||
in Python) using something like `cibuildwheel`_, remember that ``setup.py``
|
||||
and ``pyproject.toml`` are not even contained in the wheel, so this high
|
||||
Pip requirement is only for source builds, and will not affect users of
|
||||
your binary wheels. If you are building SDists and wheels, then
|
||||
`pypa-build`_ is the recommended official tool.

If you want to support old versions of Pip with the classic
|
||||
``setup_requires=["pybind11"]`` keyword argument to setup, which triggers a
|
||||
two-phase ``setup.py`` run, then you will need to use something like this to
|
||||
ensure the first pass works (which has not yet installed the ``setup_requires``
|
||||
packages, since it can't install something it does not know about):
|
||||
|
||||
.. code-block:: python
|
||||
|
||||
try:
|
||||
from pybind11.setup_helpers import Pybind11Extension
|
||||
except ImportError:
|
||||
from setuptools import Extension as Pybind11Extension
|
||||
|
||||
|
||||
It doesn't matter that the Extension class is not the enhanced subclass for the
|
||||
first pass run; and the second pass will have the ``setup_requires``
|
||||
requirements.
|
||||
|
||||
This is obviously more of a hack than the PEP 518 method, but it supports

||||
ancient versions of Pip.

The CMake command ``add_subdirectory`` will import the pybind11 project which
