title: Configuring a CI service
---
## Configuring a CI service
cibuildwheel works on many popular CI services. Others may work, but it will depend on the software installed on the CI machine/image. See the [platforms page](platforms.md) for details.
### GitHub Actions [linux/mac/windows] {: #github-actions}
To build Linux, macOS, and Windows wheels using GitHub Actions, create a `.github/workflows/build_wheels.yml` file in your repo.
!!! tab "Action"
For GitHub Actions, `cibuildwheel` provides an action you can use. This is
concise and enables easier auto updating via GitHub's Dependabot; see
[Automatic updates](faq.md#automatic-updates).
> .github/workflows/build_wheels.yml
```yaml
{% include "../examples/github-minimal.yml" %}
```
Use `env:` to pass [build options](options.md) and `with:` to set
`package-dir: .`, `output-dir: wheelhouse` and `config-file: ''`
locations (those values are the defaults).
!!! tab "pipx"
The GitHub Actions runners have pipx installed, so you can easily build in
just one line. This is internally how the action works; the main benefit of
the action form is easy updates via GitHub's Dependabot.
> .github/workflows/build_wheels.yml
```yaml
{% include "../examples/github-pipx.yml" %}
```
!!! tab "Generic"
This is the most generic form using setup-python and pip; it looks the most
like the other CI examples. If you want to avoid having setup that takes
advantage of GitHub Actions features or pipx being preinstalled, this might
appeal to you.
> .github/workflows/build_wheels.yml
{%
include-markdown "../README.md"
start="<!--generic-github-start-->"
end="<!--generic-github-end-->"
%}
Commit this file, and push to GitHub - either to your default branch, or to a PR branch. The build should start automatically.
For more info on this file, check out the [docs](https://help.github.com/en/actions/reference/workflow-syntax-for-github-actions).
[`examples/github-deploy.yml`](https://github.com/pypa/cibuildwheel/blob/main/examples/github-deploy.yml) extends this minimal example to include iOS and Pyodide builds, and a demonstration of how to automatically upload the built wheels to PyPI.
### Azure Pipelines [linux/mac/windows] {: #azure-pipelines}
To build Linux, Mac, and Windows wheels on Azure Pipelines, create a `azure-pipelines.yml` file in your repo.
> azure-pipelines.yml
```yaml
{% include "../examples/azure-pipelines-minimal.yml" %}
```
Commit this file, enable building of your repo on Azure Pipelines, and push.
Wheels will be stored for you and available through the Pipelines interface. For more info on this file, check out the [docs](https://docs.microsoft.com/en-us/azure/devops/pipelines/yaml-schema).
### Travis CI [linux/windows] {: #travis-ci}
To build Linux and Windows wheels on Travis CI, create a `.travis.yml` file in your repo.
> .travis.yml
```yaml
{% include "../examples/travis-ci-minimal.yml" %}
```
Commit this file, enable building of your repo on Travis CI, and push.
Then setup a deployment method by following the [Travis CI deployment docs](https://docs.travis-ci.com/user/deployment/), or see [Delivering to PyPI](deliver-to-pypi.md). For more info on `.travis.yml`, check out the [docs](https://docs.travis-ci.com/).
[`examples/travis-ci-deploy.yml`](https://github.com/pypa/cibuildwheel/blob/main/examples/travis-ci-deploy.yml) extends this minimal example with a demonstration of how to automatically upload the built wheels to PyPI.
### AppVeyor [linux/mac/windows] {: #appveyor}
To build Linux, Mac, and Windows wheels on AppVeyor, create an `appveyor.yml` file in your repo.
> appveyor.yml
```yaml
{% include "../examples/appveyor-minimal.yml" %}
```
Commit this file, enable building of your repo on AppVeyor, and push.
AppVeyor will store the built wheels for you - you can access them from the project console. Alternatively, you may want to store them in the same place as the Travis CI build. See [AppVeyor deployment docs](https://www.appveyor.com/docs/deployment/) for more info, or see [Delivering to PyPI](deliver-to-pypi.md) below.
For more info on this config file, check out the [docs](https://www.appveyor.com/docs/).
### CircleCI [linux/mac] {: #circleci}
To build Linux and Mac wheels on CircleCI, create a `.circleci/config.yml` file in your repo,
> .circleci/config.yml
```yaml
{% include "../examples/circleci-minimal.yml" %}
```
Commit this file, enable building of your repo on CircleCI, and push.
!!! note
CircleCI doesn't enable free macOS containers for open source by default, but you can ask for access. See [here](https://circleci.com/docs/2.0/oss/#overview) for more information.
CircleCI will store the built wheels for you - you can access them from the project console. Check out the CircleCI [docs](https://circleci.com/docs/2.0/configuration-reference/#section=configuration) for more info on this config file.
### Gitlab CI [linux] {: #gitlab-ci}
To build Linux wheels on Gitlab CI, create a `.gitlab-ci.yml` file in your repo,
> .gitlab-ci.yml
```yaml
{% include "../examples/gitlab-minimal.yml" %}
```
Commit this file, and push to Gitlab. The pipeline should start automatically.
Gitlab will store the built wheels for you - you can access them from the Pipelines view. Check out the Gitlab [docs](https://docs.gitlab.com/ee/ci/yaml/) for more info on this config file.
### Cirrus CI [linux/mac/windows] {: #cirrus-ci}
To build Linux, Mac, and Windows wheels on Cirrus CI, create a `.cirrus.yml` file in your repo,
> .cirrus.yml
```yaml
{% include "../examples/cirrus-ci-minimal.yml" %}
```
Commit this file, enable building of your repo on Cirrus CI, and push.
Cirrus CI will store the built wheels for you - you can access them from the individual task view. Check out the Cirrus CI [docs](https://cirrus-ci.org/guide/writing-tasks/) for more info on this config file.
> ⚠️ Got an error? Check the [FAQ](faq.md).
## Next steps
Once you've got the wheel building successfully, you might want to set up [testing](options.md#test-command) or [automatic releases to PyPI](deliver-to-pypi.md#automatic-method).
<script>
document.addEventListener('DOMContentLoaded', function() {
$('.toctree-l2>a, .rst-content h3').each(function(i, el) {
var text = $(el).text()
var match = text.match(/(.*) \[([a-z/]+)\]/);
if (match) {
var iconHTML = $.map(match[2].split('/'), function(ident) {
switch (ident) {
case 'linux':
return '<i class="fa fa-linux" aria-hidden="true"></i>'
case 'windows':
return '<i class="fa fa-windows" aria-hidden="true"></i>'
case 'mac':
return '<i class="fa fa-apple" aria-hidden="true"></i>'
}
}).join(' ');
$(el).append(

.append(iconHTML)
.css({float: 'right'})
)
$(el).contents()
.filter(function(){ return this.nodeType == 3; }).first()
.replaceWith(match[1]);
}
});
});
</script>

# Configuration methods
cibuildwheel can either be configured using environment variables, or from
config file such as `pyproject.toml`.
This page describes how to set options. For a full list of available options, see the [options reference](options.md).
## Environment variables {: #environment-variables}
Environment variables can be set in your CI config. For example, to configure
cibuildwheel to run tests, add the following YAML to your CI config file:
!!! tab "GitHub Actions"
> .github/workflows/*.yml ([docs](https://help.github.com/en/actions/configuring-and-managing-workflows/using-environment-variables)) (can be global, in job, or in step)
```yaml
env:
CIBW_TEST_REQUIRES: pytest
CIBW_TEST_COMMAND: "pytest ./tests"
```
!!! tab "Azure Pipelines"
> azure-pipelines.yml ([docs](https://docs.microsoft.com/en-us/azure/devops/pipelines/process/variables))
```yaml
variables:
CIBW_TEST_REQUIRES: pytest
CIBW_TEST_COMMAND: "pytest ./tests"
```
!!! tab "Travis CI"
> .travis.yml ([docs](https://docs.travis-ci.com/user/environment-variables/))
```yaml
env:
global:
- CIBW_TEST_REQUIRES=pytest
- CIBW_TEST_COMMAND="pytest ./tests"
```
!!! tab "AppVeyor"
> appveyor.yml ([docs](https://www.appveyor.com/docs/build-configuration/#environment-variables))
```yaml
environment:
global:
CIBW_TEST_REQUIRES: pytest
CIBW_TEST_COMMAND: "pytest {project}\\tests"
```
!!! tab "CircleCI"
> .circleci/config.yml ([docs](https://circleci.com/docs/2.0/configuration-reference/#environment))
```yaml
jobs:
job_name:
environment:
CIBW_TEST_REQUIRES: pytest
CIBW_TEST_COMMAND: "pytest ./tests"
```
!!! tab "Gitlab CI"
> .gitlab-ci.yml ([docs](https://docs.gitlab.com/ee/ci/variables/README.html#create-a-custom-variable-in-gitlab-ciyml))
```yaml
linux:
variables:
CIBW_TEST_REQUIRES: pytest
CIBW_TEST_COMMAND: "pytest ./tests"
```
!!! tab "Cirrus CI"
> .cirrus.yml ([docs](https://cirrus-ci.org/guide/writing-tasks/#environment-variables))
```yaml
env:
CIBW_TEST_REQUIRES: pytest
CIBW_TEST_COMMAND: "pytest ./tests"
```
## Configuration file {: #configuration-file}
You can configure cibuildwheel with a config file, such as `pyproject.toml`.
Options have the same names as the environment variable overrides, but are
placed in `[tool.cibuildwheel]` and are lower case, with dashes, following
common [TOML][https://toml.io] practice. Anything placed in subsections `linux`, `windows`,
`macos`, or `pyodide` will only affect those platforms. Lists can be used
instead of strings for items that are naturally a list. Multiline strings also
work just like in the environment variables. Environment variables will take
precedence if defined.
The example above using environment variables could have been written like this:
```toml
[tool.cibuildwheel]
test-requires = "pytest"
test-command = "pytest ./tests"
```
The complete set of defaults for the current version of cibuildwheel are shown below:
```toml
{% include "../cibuildwheel/resources/defaults.toml" %}
```
!!! tip
Static configuration works across all CI systems, and can be used locally if
you run `cibuildwheel --platform linux`. This is preferred, but environment
variables are better if you need to change per-matrix element
(`CIBW_BUILD` is often in this category, for example), or if you cannot or do
not want to change a `pyproject.toml` file. You can specify a different file to
use with `--config-file` on the command line, as well.
## Configuration overrides {: #overrides }
One feature specific to the configuration files is the ability to override
settings based on selectors. To use, add a ``tool.cibuildwheel.overrides``
array, and specify a ``select`` string. Then any options you set will only
apply to items that match that selector. These are applied in order, with later
matches overriding earlier ones if multiple selectors match. Environment
variables always override static configuration.
A few of the options below have special handling in overrides. A different
`before-all` will trigger a new container to launch on Linux, and cannot be
overridden on macOS or Windows. Overriding the image on linux will also
trigger new containers, one per image. Some commands are not supported;
`output-dir`, build/skip/test_skip selectors, and architectures cannot be
overridden.
You can specify a table of overrides in `inherit={}`, any list or table in this
list will inherit from previous overrides or the main configuration. The valid
options are `"none"` (the default), `"append"`, and `"prepend"`.
#### Examples:
```toml
[tool.cibuildwheel.linux]
before-all = "yum install mylib"
test-command = "echo 'installed'"
[[tool.cibuildwheel.overrides]]
select = "*-musllinux*"
before-all = "apk add mylib"
```
This example will override the before-all command on musllinux only, but will
still run the test-command. Note the double brackets, this is an array in TOML,
which means it can be given multiple times.
```toml
[tool.cibuildwheel]
# Normal options, etc.
manylinux-x86_64-image = "manylinux_2_34"
[[tool.cibuildwheel.overrides]]
select = "cp38-*"
manylinux-x86_64-image = "manylinux2014"
[[tool.cibuildwheel.overrides]]
select = "cp3{9,10}-*"
manylinux-x86_64-image = "manylinux_2_28"
```
This example will build CPython 3.8 wheels on manylinux2014, CPython 3.9-3.10
wheels on manylinux_2_28, and manylinux_2_34 wheels for any newer Python
(like 3.10).
```toml
[tool.cibuildwheel]
environment = {FOO="BAR", "HAM"="EGGS"}
test-command = ["pyproject"]
[[tool.cibuildwheel.overrides]]
select = "cp311*"
inherit.test-command = "prepend"
test-command = ["pyproject-before"]
inherit.environment="append"
environment = {FOO="BAZ", "PYTHON"="MONTY"}
[[tool.cibuildwheel.overrides]]
select = "cp311*"
inherit.test-command = "append"
test-command = ["pyproject-after"]
```
This example will provide the command `"pyproject-before && pyproject && pyproject-after"`
on Python 3.11, and will have `environment = {FOO="BAZ", "PYTHON"="MONTY", "HAM"="EGGS"}`.
## Extending existing options {: #inherit }
In the TOML configuration, you can choose how tables and lists are inherited.
By default, all values are overridden completely (`"none"`) but sometimes you'd
rather `"append"` or `"prepend"` to an existing list or table. You can do this
with the `inherit` table in overrides. For example, if you want to add an environment
variable for CPython 3.11, without `inherit` you'd have to repeat all the
original environment variables in the override. With `inherit`, it's just:
```toml
[[tool.cibuildwheel.overrides]]
select = "cp311*"
inherit.environment = "append"
environment.NEWVAR = "Added!"
```
For a table, `"append"` will replace a key if it exists, while `"prepend"` will
only add a new key, older keys take precedence.
Lists are also supported (and keep in mind that commands are lists). For
example, you can print a message before and after a wheel is repaired:
```toml
[[tool.cibuildwheel.overrides]]
select = "*"
inherit.repair-wheel-command = "prepend"
repair-wheel-command = "echo 'Before repair'"
[[tool.cibuildwheel.overrides]]
select = "*"
inherit.repair-wheel-command = "append"
repair-wheel-command = "echo 'After repair'"
```
As seen in this example, you can have multiple overrides match - they match top
to bottom, with the config being accumulated. If you need platform-specific
inheritance, you can use `select = "*-????linux_*"` for Linux, `select =
"*-win_*"` for Windows, and `select = "*-macosx_*"` for macOS. As always,
environment variables will completely override any TOML configuration.

## macOS and deployment target versions
OS X/macOS allows you to specify a so-called "deployment target" version that will ensure backwards compatibility with older versions of macOS. One way to do this is by setting the `MACOSX_DEPLOYMENT_TARGET` environment variable.
The [`MACOSX_DEPLOYMENT_TARGET` environment variable](platforms.md#macos-version-compatibility) is used to set the minimum deployment target for macOS.
However, to enable modern C++ standards, the deployment target needs to be set high enough (since older OS X/macOS versions did not have the necessary modern C++ standard library).
To get C++17 support, Xcode 9.3+ is needed, requiring at least macOS 10.13 on the build machine. To use C++17 library features and link against the C++ runtime library, set `MACOSX_DEPLOYMENT_TARGET` to `"10.13"` or `"10.14"` (or higher) - macOS 10.13 offers partial C++17 support (e.g., the filesystem header is in experimental, offering `#include <experimental/filesystem>` instead of `#include <filesystem>`); macOS 10.14 has full C++17 support. CPython 3.12+ require 10.13+ anyway.
However, if only C++17 compiler and standard template library (STL) features are used (not needing a C++17 runtime) it might be possible to set `MACOSX_DEPLOYMENT_TARGET` to a lower value, such as `"10.9"`. To find out if this is the case, try compiling and running with a lower `MACOSX_DEPLOYMENT_TARGET`: if C++17 features are used that require a more recent deployment target, building the wheel should fail.

```bash
# Either download the SDist from your CI, or make it:
# Clear out your 'dist' folder.
rm -rf dist

If you don't need much control over the release of a package, you can set up
cibuildwheel to deliver the wheels straight to PyPI. You just need to bump the
your CI provider to deliver the wheels straight to PyPI. You just need to bump the
version and tag it.
### Generic instructions
The exact way to set it up varies, depending on which CI provider you're using. But generally, the process goes like this:
Make your SDist with the [build](https://github.com/pypa/build) tool, and your wheels with cibuildwheel. If you can make the files available as
downloadable artifacts, this make testing before releases easier (depending on your CI provider's options). The "publish" job/step should collect the
files, and then run `twine upload <paths>` (possibly via [pipx](https://github.com/pypa/pipx)); this should only happen on tags or "releases".
- Build your wheels with cibuildwheel
- Build an sdist with the [build](https://github.com/pypa/build) tool
- Check that the current CI run is happening during a release (e.g. it's in response to a vXX tag)
- Collect these assets together onto one runner
- Upload them to PyPI using `twine upload <paths>`

GitHub actions has pipx in all the runners as a supported package manager, as
well as several useful actions. Alongside your existing job(s) that runs cibuildwheel to make wheels, you will probably want to build an SDist:

## Tips
### Linux builds in containers
Linux wheels are built in [`manylinux`/`musllinux` containers](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 600](https://www.python.org/dev/peps/pep-0600/) / [PEP 656](https://www.python.org/dev/peps/pep-0656/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
- Programs and libraries are not installed on the CI runner host, but rather should be installed inside the container - using `yum` for `manylinux2014`, `apt-get` for `manylinux_2_31`, `dnf` for `manylinux_2_28` and `apk` for `musllinux_1_1` or `musllinux_1_2`, or manually. The same goes for environment variables that are potentially needed to customize the wheel building.
`cibuildwheel` supports this by providing the [`CIBW_ENVIRONMENT`](options.md#environment) and [`CIBW_BEFORE_ALL`](options.md#before-all) options to setup the build environment inside the running container.
- The project directory is copied into the container as `/project`, the output directory for the wheels to be copied out is `/output`. In general, this is handled transparently by `cibuildwheel`. For a more finegrained level of control however, the root of the host file system is mounted as `/host`, allowing for example to access shared files, caches, etc. on the host file system. Note that `/host` is not available on CircleCI and GitLab CI due to their Docker policies.
- Alternative Docker images can be specified with the `CIBW_MANYLINUX_*_IMAGE`/`CIBW_MUSLLINUX_*_IMAGE` options to allow for a custom, preconfigured build environment for the Linux builds. See [options](options.md#linux-image) for more details.
### Building macOS wheels for Apple Silicon {: #apple-silicon}
`cibuildwheel` supports both native builds and cross-compiling between `arm64` (Apple Silicon) and `x86_64` (Intel) architectures, including the cross-compatible `universal2` format.
#### Overview of Mac architectures
You have several choices for wheels for Python 3.8+:
##### `x86_64`
The traditional wheel for Apple, loads on Intel machines, and on
Apple Silicon when running Python under Rosetta 2 emulation.
Due to a change in naming, Pip 20.3+ (or an installer using packaging 20.5+)
is required to install a binary wheel on macOS Big Sur.
##### `arm64`
The native wheel for macOS on Apple Silicon.
Requires Pip 20.3+ (or packaging 20.5+) to install.
##### `universal2`
This wheel contains both architectures, causing it to be up to twice the
size (data files do not get doubled, only compiled code). It requires
Pip 20.3 (Packaging 20.6+) to load on Intel, and Pip 21.0.1 (Packaging 20.9+)
to load on Apple Silicon.
The dual-architecture `universal2` has a few benefits, but a key benefit
to a universal wheel is that a user can bundle these wheels into an
application and ship a single binary.
However, if you have a large library, then you might prefer to ship
the two single-arch wheels instead - `x86_64` and `arm64`. In rare cases,
you might want to build all three, but in that case, pip will not download
the universal wheels, because it prefers the most specific wheel
available.
#### What to provide?
Generally speaking, because Pip 20.3 is required for the `universal2` wheel,
most packages should provide both `x86_64` and one of `universal2`/`arm64`
wheels. When Pip 20.3+ is common on macOS, then it might be possible to ship
only the `universal2` wheel.
Opinions vary on which of arch-specific or `universal2` wheels are best - some packagers prefer `universal2` because it's one wheel for all Mac users, so simpler, and easier to build into apps for downstream users. However, because they contain code for both architectures, their file size is larger, meaning they consume more disk space and bandwidth, and are harder to build for some projects.
See [GitHub issue 1333](https://github.com/pypa/cibuildwheel/issues/1333) for more discussion.
#### How?
It's easiest to build `x86_64` wheels on `x86_64` runners, and `arm64` wheels on `arm64` runners.
On GitHub Actions, `macos-14` runners are `arm64`, and `macos-13` runners are `x86_64`. So all you need to do is ensure both are in your build matrix.
#### Cross-compiling
If your CI provider doesn't offer arm64 runners yet, or you want to create `universal2`, you'll have to cross-compile. Cross-compilation can be enabled by adding extra archs to the [`CIBW_ARCHS_MACOS` option](options.md#archs) - e.g. `CIBW_ARCHS_MACOS="x86_64 universal2"`. Cross-compilation is provided by Xcode toolchain v12.2+.
Regarding testing,
- On an arm64 runner, it is possible to test x86_64 wheels and both parts of a universal2 wheel using Rosetta 2 emulation.
- On an x86_64 runner, arm64 code can be compiled but it can't be tested. `cibuildwheel` will raise a warning to notify you of this - these warnings can be silenced by skipping testing on these platforms: `CIBW_TEST_SKIP: "*_arm64 *_universal2:arm64"`.
!!! note
If your project uses **Poetry** as a build backend, cross-compiling on macOS [does not currently work](https://github.com/python-poetry/poetry/issues/7107). In some cases arm64 wheels can be built but their tags will be incorrect, with the platform tag showing `x86_64` instead of `arm64`.
As a workaround, the tag can be fixed before running delocate to repair the wheel. The [`wheel tags`](https://wheel.readthedocs.io/en/stable/reference/wheel_tags.html) command is ideal for this. See [this workflow](https://gist.github.com/anderssonjohan/49f07e33fc5cb2420515a8ac76dc0c95#file-build-pendulum-wheels-yml-L39-L53) for an example usage of `wheel tags`.

### Windows ARM64 builds {: #windows-arm64}
`cibuildwheel` supports cross-compiling `ARM64` wheels on all Windows runners, but a native ARM64 runner is required for testing. On non-native runners, tests for ARM64 wheels will be automatically skipped with a warning. Add `"*-win_arm64"` to your `CIBW_TEST_SKIP` setting to suppress the warning.
Cross-compilation on Windows relies on a supported build backend. Supported backends use an environment variable to specify their target platform (the one they are compiling native modules for, as opposed to the one they are running on), which is set in [cibuildwheels/windows.py](https://github.com/pypa/cibuildwheel/blob/main/cibuildwheel/windows.py) before building. Currently, `setuptools>=65.4.1` and `setuptools_rust` are the only supported backends.
By default, `ARM64` is not enabled when running on non-ARM64 runners. Use [`CIBW_ARCHS`](options.md#archs) to select it.

# Options
## Setting options
cibuildwheel can either be configured using environment variables, or from
config file such as `pyproject.toml`.
### Environment variables {: #environment-variables}
Environment variables can be set in your CI config. For example, to configure
cibuildwheel to run tests, add the following YAML to your CI config file:
!!! tab "GitHub Actions"
> .github/workflows/*.yml ([docs](https://help.github.com/en/actions/configuring-and-managing-workflows/using-environment-variables)) (can be global, in job, or in step)

```yaml
env:

CIBW_TEST_COMMAND: "pytest {project}/tests"
```
### Configuration file {: #configuration-file}
You can configure cibuildwheel with a config file, such as `pyproject.toml`.
Options have the same names as the environment variable overrides, but are
placed in `[tool.cibuildwheel]` and are lower case, with dashes, following
common [TOML][] practice. Anything placed in subsections `linux`, `windows`,
`macos`, or `pyodide` will only affect those platforms. Lists can be used
instead of strings for items that are naturally a list. Multiline strings also
work just like in the environment variables. Environment variables will take
precedence if defined.
The example above using environment variables could have been written like this:
```toml
[tool.cibuildwheel]
test-requires = "pytest"
test-command = "pytest {project}/tests"
```
The complete set of defaults for the current version of cibuildwheel are shown below:
```toml
{% include "../cibuildwheel/resources/defaults.toml" %}
```
!!! tip
Static configuration works across all CI systems, and can be used locally if
you run `cibuildwheel --platform linux`. This is preferred, but environment
variables are better if you need to change per-matrix element
(`CIBW_BUILD` is often in this category, for example), or if you cannot or do
not want to change a `pyproject.toml` file. You can specify a different file to
use with `--config-file` on the command line, as well.
### Configuration overrides {: #overrides }
One feature specific to the configuration files is the ability to override
settings based on selectors. To use, add a ``tool.cibuildwheel.overrides``
array, and specify a ``select`` string. Then any options you set will only
apply to items that match that selector. These are applied in order, with later
matches overriding earlier ones if multiple selectors match. Environment
variables always override static configuration.
A few of the options below have special handling in overrides. A different
`before-all` will trigger a new container to launch on Linux, and cannot be
overridden on macOS or Windows. Overriding the image on linux will also
trigger new containers, one per image. Some commands are not supported;
`output-dir`, build/skip/test_skip selectors, and architectures cannot be
overridden.
You can specify a table of overrides in `inherit={}`, any list or table in this
list will inherit from previous overrides or the main configuration. The valid
options are `"none"` (the default), `"append"`, and `"prepend"`.
##### Examples:
```toml
[tool.cibuildwheel.linux]
before-all = "yum install mylib"
test-command = "echo 'installed'"
[[tool.cibuildwheel.overrides]]
select = "*-musllinux*"
before-all = "apk add mylib"
```
This example will override the before-all command on musllinux only, but will
still run the test-command. Note the double brackets, this is an array in TOML,
which means it can be given multiple times.
```toml
[tool.cibuildwheel]
# Normal options, etc.
manylinux-x86_64-image = "manylinux_2_34"
[[tool.cibuildwheel.overrides]]
select = "cp38-*"
manylinux-x86_64-image = "manylinux2014"
[[tool.cibuildwheel.overrides]]
select = "cp3{9,10}-*"
manylinux-x86_64-image = "manylinux_2_28"
```
This example will build CPython 3.8 wheels on manylinux2014, CPython 3.9-3.10
wheels on manylinux_2_28, and manylinux_2_34 wheels for any newer Python
(like 3.10).
```toml
[tool.cibuildwheel]
environment = {FOO="BAR", "HAM"="EGGS"}
test-command = ["pyproject"]
[[tool.cibuildwheel.overrides]]
select = "cp311*"
inherit.test-command = "prepend"
test-command = ["pyproject-before"]
inherit.environment="append"
environment = {FOO="BAZ", "PYTHON"="MONTY"}
[[tool.cibuildwheel.overrides]]
select = "cp311*"
inherit.test-command = "append"
test-command = ["pyproject-after"]
```
This example will provide the command `"pyproject-before && pyproject && pyproject-after"`
on Python 3.11, and will have `environment = {FOO="BAZ", "PYTHON"="MONTY", "HAM"="EGGS"}`.
### Extending existing options {: #inherit }
In the TOML configuration, you can choose how tables and lists are inherited.
By default, all values are overridden completely (`"none"`) but sometimes you'd
rather `"append"` or `"prepend"` to an existing list or table. You can do this
with the `inherit` table in overrides. For example, if you want to add an environment
variable for CPython 3.11, without `inherit` you'd have to repeat all the
original environment variables in the override. With `inherit`, it's just:
```toml
[[tool.cibuildwheel.overrides]]
select = "cp311*"
inherit.environment = "append"
environment.NEWVAR = "Added!"
```
For a table, `"append"` will replace a key if it exists, while `"prepend"` will
only add a new key, older keys take precedence.
Lists are also supported (and keep in mind that commands are lists). For
example, you can print a message before and after a wheel is repaired:
```toml
[[tool.cibuildwheel.overrides]]
select = "*"
inherit.repair-wheel-command = "prepend"
repair-wheel-command = "echo 'Before repair'"
[[tool.cibuildwheel.overrides]]
select = "*"
inherit.repair-wheel-command = "append"
repair-wheel-command = "echo 'After repair'"
```
As seen in this example, you can have multiple overrides match - they match top
to bottom, with the config being accumulated. If you need platform-specific
inheritance, you can use `select = "*-????linux_*"` for Linux, `select =
"*-win_*"` for Windows, and `select = "*-macosx_*"` for macOS. As always,
environment variables will completely override any TOML configuration.

# Platforms
## Linux
### System requirements
If you've got [Docker](https://www.docker.com/get-started/) installed on your development machine, you can run a Linux build.
!!! tip
You can run the Linux build on any platform. Even Windows can run
Linux containers these days, but there are a few hoops to jump
through. Check [this document](https://docs.microsoft.com/en-us/virtualization/windowscontainers/quick-start/quick-start-windows-10-linux)
for more info.
Because the builds are happening in manylinux Docker containers, they're perfectly reproducible.
The only side effect to your system will be docker images being pulled.
### Build containers {: #linux-containers}
Linux wheels are built in [`manylinux`/`musllinux` containers](https://github.com/pypa/manylinux) to provide binary compatible wheels on Linux, according to [PEP 600](https://www.python.org/dev/peps/pep-0600/) / [PEP 656](https://www.python.org/dev/peps/pep-0656/). Because of this, when building with `cibuildwheel` on Linux, a few things should be taken into account:
- Programs and libraries are not installed on the CI runner host, but rather should be installed inside the container - using `yum` for `manylinux2014`, `apt-get` for `manylinux_2_31`, `dnf` for `manylinux_2_28` and `apk` for `musllinux_1_1` or `musllinux_1_2`, or manually. The same goes for environment variables that are potentially needed to customize the wheel building.
`cibuildwheel` supports this by providing the [`CIBW_ENVIRONMENT`](options.md#environment) and [`CIBW_BEFORE_ALL`](options.md#before-all) options to setup the build environment inside the running container.
- The project directory is copied into the container as `/project`, the output directory for the wheels to be copied out is `/output`. In general, this is handled transparently by `cibuildwheel`. For a more finegrained level of control however, the root of the host file system is mounted as `/host`, allowing for example to access shared files, caches, etc. on the host file system. Note that `/host` is not available on CircleCI and GitLab CI due to their Docker policies.
- Alternative Docker images can be specified with the `CIBW_MANYLINUX_*_IMAGE`/`CIBW_MUSLLINUX_*_IMAGE` options to allow for a custom, preconfigured build environment for the Linux builds. See [options](options.md#linux-image) for more details.
## macOS
### System requirements
You need to have native build tools installed. Use `xcode-select --install` to install the Xcode command line tools.
Because the builds are happening without full isolation, there might be some differences compared to CI builds (Xcode version, OS version, local files, ...) that might prevent you from finding an issue only seen in CI.
In order to speed-up builds, cibuildwheel will cache the tools it needs to be reused for future builds. The folder used for caching is system/user dependent and is reported in the printed preamble of each run (e.g. `Cache folder: /Users/Matt/Library/Caches/cibuildwheel`). You can override the cache folder using the `CIBW_CACHE_PATH` environment variable.
!!! warning
cibuildwheel uses official python.org macOS installers for CPython but those can only be installed globally.
In order not to mess with your system, cibuildwheel won't install those if they are missing. Instead, it will error out with a message to let you install the missing CPython:
```console
Error: CPython 3.9 is not installed.
cibuildwheel will not perform system-wide installs when running outside of CI.
To build locally, install CPython 3.9 on this machine, or, disable this version of Python using CIBW_SKIP=cp39-macosx_*
Download link: https://www.python.org/ftp/python/3.9.8/python-3.9.8-macosx10.9.pkg
```
### macOS Version Compatibility
macOS allows you to specify a "deployment target" version that will ensure backwards compatibility with older versions of macOS. For most projects, the way to do this is to set the `MACOSX_DEPLOYMENT_TARGET` environment variable.
macOS builds will honor the `MACOSX_DEPLOYMENT_TARGET` environment variable to control the minimum supported macOS version for generated wheels. The lowest value you can set `MACOSX_DEPLOYMENT_TARGET` is as follows:
| Arch | Python version range | Minimum target |
|-------|----------------------|----------------|
| Intel | CPython 3.8-3.11 | 10.9 |
| Intel | CPython 3.12+ | 10.13 |
| AS | CPython or PyPy | 11 |
| Intel | PyPy 3.8 | 10.13 |
| Intel | PyPy 3.9+ | 10.15 |
If you set the value lower, cibuildwheel will cap it to the lowest supported value for each target as needed.
!!! note
For Rust-based extensions, `Rustc` requires `MACOSX_DEPLOYMENT_TARGET` to be at
least 10.12. However, `cibuildwheel` defaults to 10.9 for
**Intel / CPython 3.8-3.11** builds. Users must manually set
`MACOSX_DEPLOYMENT_TARGET` to 10.12 or higher when building Rust extensions.
### macOS architectures
`cibuildwheel` supports both native builds and cross-compiling between `arm64` (Apple Silicon) and `x86_64` (Intel) architectures, including the cross-compatible `universal2` format. By default, macOS builds will build a single architecture wheel, using the build machine's architecture.
If you need to support both x86_64 and Apple Silicon, you can use the `CIBW_ARCHS` environment variable to specify the architectures you want to build, or the value `universal2` to build a multi-architecture wheel. cibuildwheel _will_ test x86_64 wheels (or the x86_64 slice of a `universal2` wheel) when running on Apple Silicon hardware using Rosetta 2 emulation, but it is *not* possible to test Apple Silicon wheels on x86_64 hardware.
#### Overview of Mac architectures
##### `x86_64`
The traditional wheel for Apple, loads on Intel machines, and on
Apple Silicon when running Python under Rosetta 2 emulation.
Due to a change in naming, Pip 20.3+ (or an installer using packaging 20.5+)
is required to install a binary wheel on macOS Big Sur.
##### `arm64`
The native wheel for macOS on Apple Silicon.
##### `universal2`
This wheel contains both architectures, causing it to be up to twice the
size (data files do not get doubled, only compiled code).
The dual-architecture `universal2` has a few benefits, but a key benefit
to a universal wheel is that a user can bundle these wheels into an
application and ship a single binary.
However, if you have a large library, then you might prefer to ship
the two single-arch wheels instead - `x86_64` and `arm64`. In rare cases,
you might want to build all three, but in that case, pip will not download
the universal wheels, because it prefers the most specific wheel
available.
#### What to provide?
Opinions vary on which of arch-specific or `universal2` wheels are best - some packagers prefer `universal2` because it's one wheel for all Mac users, so simpler, and easier to build into apps for downstream users. However, because they contain code for both architectures, their file size is larger, meaning they consume more disk space and bandwidth, and are harder to build for some projects.
See [GitHub issue 1333](https://github.com/pypa/cibuildwheel/issues/1333) for more discussion.
#### How?
It's easiest to build `x86_64` wheels on `x86_64` runners, and `arm64` wheels on `arm64` runners.
On GitHub Actions, `macos-14` runners are `arm64`, and `macos-13` runners are `x86_64`. So all you need to do is ensure both are in your build matrix.
#### Cross-compiling
If your CI provider doesn't offer arm64 runners yet, or you want to create `universal2`, you'll have to cross-compile. Cross-compilation can be enabled by adding extra archs to the [`CIBW_ARCHS_MACOS` option](options.md#archs) - e.g. `CIBW_ARCHS_MACOS="x86_64 universal2"`. Cross-compilation is provided by Xcode toolchain v12.2+.
Regarding testing,
- On an arm64 runner, it is possible to test x86_64 wheels and both parts of a universal2 wheel using Rosetta 2 emulation.
- On an x86_64 runner, arm64 code can be compiled but it can't be tested. `cibuildwheel` will raise a warning to notify you of this - these warnings can be silenced by skipping testing on these platforms: `CIBW_TEST_SKIP: "*_arm64 *_universal2:arm64"`.
!!! note
If your project uses **Poetry** as a build backend, cross-compiling on macOS [does not currently work](https://github.com/python-poetry/poetry/issues/7107). In some cases arm64 wheels can be built but their tags will be incorrect, with the platform tag showing `x86_64` instead of `arm64`.
As a workaround, the tag can be fixed before running delocate to repair the wheel. The [`wheel tags`](https://wheel.readthedocs.io/en/stable/reference/wheel_tags.html) command is ideal for this. See [this workflow](https://gist.github.com/anderssonjohan/49f07e33fc5cb2420515a8ac76dc0c95#file-build-pendulum-wheels-yml-L39-L53) for an example usage of `wheel tags`.
## Windows
### System requirements
You must have native build tools (i.e., Visual Studio) installed.
Because the builds are happening without full isolation, there might be some differences compared to CI builds (Visual Studio version, OS version, local files, ...) that might prevent you from finding an issue only seen in CI.
In order to speed-up builds, cibuildwheel will cache the tools it needs to be reused for future builds. The folder used for caching is system/user dependent and is reported in the printed preamble of each run (e.g. `Cache folder: C:\Users\Matt\AppData\Local\pypa\cibuildwheel\Cache`). You can override the cache folder using the ``CIBW_CACHE_PATH`` environment variable.
### Windows ARM64 builds {: #windows-arm64}
`cibuildwheel` supports cross-compiling `ARM64` wheels on all Windows runners, but a native ARM64 runner is required for testing. On non-native runners, tests for ARM64 wheels will be automatically skipped with a warning. Add `"*-win_arm64"` to your `CIBW_TEST_SKIP` setting to suppress the warning.
Cross-compilation on Windows relies on a supported build backend. Supported backends use an environment variable to specify their target platform (the one they are compiling native modules for, as opposed to the one they are running on), which is set in [cibuildwheels/windows.py](https://github.com/pypa/cibuildwheel/blob/main/cibuildwheel/windows.py) before building. Currently, `setuptools>=65.4.1` and `setuptools_rust` are the only supported backends.
By default, `ARM64` is not enabled when running on non-ARM64 runners. Use [`CIBW_ARCHS`](options.md#archs) to select it.
## Pyodide/WebAssembly {: #pyodide}
Pyodide is offered as an experimental feature in cibuildwheel.
### Prerequisites
You need to have a matching host version of Python (unlike all other cibuildwheel platforms). Linux host highly recommended; macOS hosts may work (e.g. invoking `pytest` directly in [`CIBW_TEST_COMMAND`](options.md#test-command) is [currently failing](https://github.com/pyodide/pyodide/issues/4802)) and Windows hosts will not work.
### Specifying a pyodide build
You must target pyodide with `--platform pyodide` (or use `--only` on the identifier).
## iOS
### System requirements
You must be building on a macOS machine, with Xcode installed. The Xcode installation must have an iOS SDK available, with all license agreements agreed to by the user. To check if an iOS SDK is available, open the Xcode settings panel, and check the Platforms tab. This will also ensure that license agreements have been acknowledged.
Building iOS wheels also requires a working macOS Python installation. See the notes on [macOS builds](#macos) for details about configuration of the macOS environment.
### Specifying an iOS build
iOS is effectively 2 platforms - physical devices, and simulators. While the API for these two platforms are identical, the ABI is not compatible, even when dealing with a device and simulator with the same CPU architecture. For this reason, the architecture specification for iOS builds includes *both* the CPU architecture *and* the ABI that is being targeted. There are three possible values for architecture on iOS; the values match those used by `sys.implementation._multiarch` when running on iOS (with hyphens replaced with underscores, matching wheel filename normalization):
* `arm64_iphoneos` (for physical iOS devices);
* `arm64_iphonesimulator` (for iOS simulators running on Apple Silicon macOS machines); and
* `x64_64_iphonesimulator` (for iOS simulators running on Intel macOS machines).
By default, cibuildwheel will build wheels for all three of these targets.
If you need to specify different compilation flags or other properties on a per-ABI or per-CPU basis, you can use [configuration overrides](configuration.md#overrides) with a `select` clause that targets the specific ABI or architecture. For example, consider the following example:
```
[tool.cibuildwheel.ios]
test-sources = ["tests"]
test-requires = ["pytest"]
[[tool.cibuildwheel.overrides]]
select = "*_iphoneos"
environment.PATH = "/path/to/special/device/details:..."
[[tool.cibuildwheel.overrides]]
select = "*-ios_arm64_*"
inherit.test-requires = "append"
test-requires = ["arm64-testing-helper"]
```
This configuration would:
* Specify a `test-sources` and `test-requires` for all iOS targets;
* Add a `PATH` setting that will be used on physical iOS devices; and
* Add `arm64-testing-helper` to the test environment for all ARM64 iOS devices (whether simulator or device).
### iOS version compatibility
iOS builds will honor the `IPHONEOS_DEPLOYMENT_TARGET` environment variable to set the minimum supported API version for generated wheels. This will default to `13.0` if the environment variable isn't set.
### Cross platform builds
iOS builds are *cross platform builds*, as it not possible to run compilers and other build tools "on device". The pre-compiled iOS binaries used to support iOS builds include tooling that can convert any virtual environment into a cross platform virtual environment - that is, an environment that can run binaries on the build machine (macOS), but, if asked, will respond as if it is an iOS machine. This allows `pip`, `build`, and other build tools to perform iOS-appropriate behaviour.
### Build frontend support
iOS builds support both the `pip` and `build` build frontends. In principle, support for `uv` with the `build[uv]` frontend should be possible, but `uv` [doesn't currently have support for cross-platform builds](https://github.com/astral-sh/uv/issues/7957), and [doesn't have support for iOS (or Android) tags](https://github.com/astral-sh/uv/issues/8029).
### Build environment
The environment used to run builds does not inherit the full user environment - in particular, `PATH` is deliberately re-written. This is because UNIX C tooling doesn't do a great job differentiating between "macOS ARM64" and "iOS ARM64" binaries. If (for example) Homebrew is on the path when compilation commands are invoked, it's easy for a macOS version of a library to be linked into the iOS binary, rendering it unusable on iOS. To prevent this, iOS builds always force `PATH` to a "known minimal" path, that includes only the bare system utilities, and the iOS compiler toolchain.
If your project requires additional tools to build (such as `cmake`, `ninja`, or `rustc`), those tools must be explicitly declared as cross-build tools using [`CIBW_XBUILD_TOOLS`](options.md#xbuild-tools). *Any* tool used by the build process must be included in the `CIBW_XBUILD_TOOLS` list, not just tools that cibuildwheel will invoke directly. For example, if your build script invokes `cmake`, and the `cmake` script invokes `magick` to perform some image transformations, both `cmake` and `magick` must be included in your cross-build tools list.
### Tests
If tests have been configured, the test suite will be executed on the simulator matching the architecture of the build machine - that is, if you're building on an ARM64 macOS machine, the ARM64 wheel will be tested on an ARM64 simulator. It is not possible to use cibuildwheel to test wheels on other simulators, or on physical devices.
The iOS test environment can't support running shell scripts, so the [`CIBW_TEST_COMMAND`](options.md#test-command) value must be specified as if it were a command line being passed to `python -m ...`. In addition, the project must use [`CIBW_TEST_SOURCES`](options.md#test-sources) to specify the minimum subset of files that should be copied to the test environment. This is because the test must be run "on device", and the simulator device will not have access to the local project directory.
The test process uses the same testbed used by CPython itself to run the CPython test suite. It is an Xcode project that has been configured to have a single Xcode "XCUnit" test - the result of which reports the success or failure of running `python -m <CIBW_TEST_COMMAND>`.

If you've got [Docker](https://www.docker.com/products/docker-desktop) installed on your development machine, you can run a Linux build.
!!! tip
You can run the Linux build on any platform. Even Windows can run
Linux containers these days, but there are a few hoops to jump
through. Check [this document](https://docs.microsoft.com/en-us/virtualization/windowscontainers/quick-start/quick-start-windows-10-linux)

To build Linux, macOS, and Windows wheels using GitHub Actions, create a `.github/workflows/build_wheels.yml` file in your repo.
!!! tab "Action"
For GitHub Actions, `cibuildwheel` provides an action you can use. This is
concise and enables easier auto updating via GitHub's Dependabot; see
[Automatic updates](faq.md#automatic-updates).
> .github/workflows/build_wheels.yml
```yaml
{% include "../examples/github-minimal.yml" %}

Use `env:` to pass [build options](options.md) and `with:` to set
`package-dir: .`, `output-dir: wheelhouse` and `config-file: ''`
locations (those values are the defaults).
!!! tab "pipx"
The GitHub Actions runners have pipx installed, so you can easily build in
just one line. This is internally how the action works; the main benefit of
the action form is easy updates via GitHub's Dependabot.

!!! tab "Generic"
This is the most generic form using setup-python and pip; it looks the most
like the other CI examples. If you want to avoid having setup that takes
advantage of GitHub Actions features or pipx being preinstalled, this might
appeal to you.

## Next steps
Once you've got the wheel building successfully, you might want to set up [testing](options.md#test-command) or [automatic releases to PyPI](deliver-to-pypi.md#automatic-method).
<script>
document.addEventListener('DOMContentLoaded', function() {
$('.toctree-l3>a, .rst-content h3').each(function(i, el) {
var text = $(el).text()
var match = text.match(/(.*) \[([a-z/]+)\]/);
if (match) {
var iconHTML = $.map(match[2].split('/'), function(ident) {
switch (ident) {
case 'linux':
return '<i class="fa fa-linux" aria-hidden="true"></i>'
case 'windows':
return '<i class="fa fa-windows" aria-hidden="true"></i>'
case 'mac':

}
}).join(' ');
$(el).append(

.append(iconHTML)
.css({float: 'right'})
)
$(el).contents()
.filter(function(){ return this.nodeType == 3; }).first()
.replaceWith(match[1]);
}
});
