 So, if we can, I'd like to improve the experience on errors as well. In [this](https://github.com/pypa/cibuildwheel/issues/139) case, it takes a bit of knowledge to understand that the Linux builds are happening in a different OS via Docker, that the linked symbols won't match, that auditwheel will fail because of this. A problem with how the tools fit together, instead of the tools themselves.
 
-## Development
+Maintainer notes
+----------------
 
-### Running the tests
+### Local testing
 
-When making a change to the codebase, you can run tests locally for quicker feedback than the CI runs on a PR. You can [run them directly](#making-a-venv), but the easiest way to run tests is using [nox](https://nox.thea.codes/).
+You should run:
 
-You can run all the tests locally by doing:
-
-```bash
-nox -s tests
-```
-
-However, because this takes a while, you might prefer to be more specific.
-
-#### Unit tests
-
-To run the project's unit tests, do:
-
-```bash
-nox -s tests -- unit_test
-```
-
-There are a few custom options to enable different parts of the test suite - check `nox -s tests -- unit_test --help` for details.
-
-If you're calling this a lot, you might consider using the `-r` or `-R` arguments to nox to make it a bit faster. This calls pytest under the hood, so to target a specific test, use pytest's `-k` option after the `--` above to select a specific test.
-
-#### Integration tests
-
-To run the project's integration tests, do:
-
-```bash
-nox -s tests -- test
-```
-
-The integration test suite is big - it can take more than 30 minutes to run the whole thing.
-
-Because it takes such a long time, normally you'd choose specific tests to run locally, and rely on the project's CI for the rest. Use pytest's `-k` option to choose specific tests. You can pass a test name or a filename, it'll run everything that matches.
-
-```bash
-nox -s tests -- test -k <test_name_or_filename>
-# e.g.
-nox -s tests -- test -k before_build
-```
-
-A few notes-
-
-- Because they run inside a container, Linux tests can run on all platforms where Docker is installed, so they're convenient for running integration tests locally. Set CIBW_PLATFORM to do this: `CIBW_PLATFORM=linux nox -s tests -- test`.
-
-- Running the macOS integration tests requires _system installs_ of Python from python.org for all the versions that are tested. We won't attempt to install these when running locally, but you can do so manually using the URL in the error message that is printed when the install is not found.
-
-#### Making a venv
-
-More advanced users might prefer to invoke pytest directly-
-
-```bash
-python3 -m venv .venv
-source .venv/bin/activate
+```python
+python3 -m venv venv
+. venv/bin/activate
 pip install -e .[dev]
-# run the unit tests
-pytest unit_test
-# run the whole integration test suite
-pytest test
-# run a specific integration test
-pytest test -k test_build_frontend_args
-# run a specific integration test on a different platform
-CIBW_PLATFORM=linux pytest test -k test_build_frontend_args
 ```
 
-### Linting, docs
-
-Most developer tasks have a nox interface. This allows you to very simply run tasks without worrying about setting up a development environment (as shown below). This is a slower than setting up a development environment and reusing it, but has the (important) benefit of being highly reproducible; an earlier run does not affect a current run, or anything else on your machine.
-
-You can see a list of sessions by typing `nox -l`; here are a few common ones:
-
-```console
-nox -s lint                    # Run the linters (default)
-nox -s tests [-- PYTEST-ARGS]  # Run the tests   (default)
-nox -s docs                    # Build and serve the documentation
-nox -s build                   # Make SDist and wheel
-```
-
-More advanced users can run the update scripts. `update_pins` should work directly, but `update_constraints` needs all versions of Python installed. If you don't want to do that locally, a fast way to run it to use docker to run nox:
-
-```console
-docker run --rm -itv $PWD:/src -w /src quay.io/pypa/manylinux_2_24_x86_64:latest pipx run nox -s update_constraints
-```

-# Modern C++ standards

 Building Python wheels with modern C++ standards (C++11 and later) requires a few tricks.
 
 
+## Python 2.7 and C++17
+
+The Python 2.7 header files use the `register` keyword, which is [reserved and unused from C+17 onwards](https://en.cppreference.com/w/cpp/keyword/register). Compiling a wheel for Python 2.7 with the C++17 standard is still possible to allow usage of `register` using proper flag `-Wno-register` for gcc/clang and `/wd5033` for MSVC.

 ## manylinux1 and C++14
-The past end-of-life `manylinux1` image (based on CentOS 5) contains a version of GCC and libstdc++ that only supports C++11 and earlier standards. There are however ways to compile wheels with the C++14 standard (and later): https://github.com/pypa/manylinux/issues/118

 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.
 
-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).
+However, to enable modern C++ standards, the deploment 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++11 and C++14 support, `MACOSX_DEPLOYMENT_TARGET` needs to be set to (at least) `"10.9"`. By default, `cibuildwheel` already does this, building 64-bit-only wheels for macOS 10.9 and later.
 
-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.
 
 For more details see https://en.cppreference.com/w/cpp/compiler_support, https://en.wikipedia.org/wiki/Xcode, and https://xcodereleases.com/: Xcode 10 needs macOS 10.13 and Xcode 11 needs macOS 10.14.
+
+## Windows and Python 2.7
+
+In previous years, Microsoft distributed a compiler toolchain called 'Visual C++ for Python 2.7', which was a distribution of MSVC 2008 that was created to make it easier to build Python 2.7 extensions on Windows, because it was fully compatible with the toolchain that built Python 2.7.
+
+This toolchain does not support modern C++ standards (i.e., C++11 and later). And it is hard to find this toolchain these days, since Microsoft removed the download for the required Visual Studio 2008 needed to build a native extension in April, 2021. So, by default, cibuildwheel does not attempt to build Python 2.7 extensions on Windows.

+There is an optional workaround, though: the pybind11 project argues and shows that it is [possible to compile Python 2.7 extension with a newer compiler](https://pybind11.readthedocs.io/en/stable/faq.html#working-with-ancient-visual-studio-2008-builds-on-windows) and has an example project showing how to do this: https://github.com/pybind/python_example. The main catch is that a user might need to install [a newer "Microsoft Visual C++ Redistributable"](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads), since the newer C++ standard library's binaries are not included by default with the Python 2.7 installation.
+
+Forcing `distutils` or `setuptools` to use a more recent version of MSVC that supports modern C++ can be done in the following way:
+
+1. Set the environment variables `DISTUTILS_USE_SDK=1` and `MSSdk=1`. These two environment variables will tell `distutils`/`setuptools` to not search and set up a build environment that uses Visual C++ for Python 2.7 (aka. MSVC 9).
+2. Set up the build Visual Studio build environment you want to use, making sure that e.g. `PATH` contains `cl`, `link`, etc.
+    - Usually, this can be done through `vcvarsall.bat x86` or `vcvarsall.bat x64`. The exact location of this file depends on the installation, but the default path for VS 2019 Community (e.g. used in AppVeyor's `Visual Studio 2019` image) is `C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat`. **Note**: `vcvarsall.bat` changes the environment variables, so this cannot be run in a subprocess/subshell and consequently running `vsvarsall.bat` in `CIBW_BEFORE_BUILD` does not have any effect.
+    - In Azure Pipelines, [a `VSBuild` task is available](https://docs.microsoft.com/en-us/azure/devops/pipelines/tasks/build/visual-studio-build)
+    - In GitHub Actions, the default shell is powershell, so you'll need to use `shell: cmd` to source a `.bat` file, and the directory is `"C:\Program Files (x86)\Microsoft Visual Studio\2019\Enterprise\VC\Auxiliary\Build\vcvarsall.bat"`. Or you can use an action, such as the [`ilammy/msvc-dev-cmd@v1`](https://github.com/ilammy/msvc-dev-cmd) action to setup the environment (see example below).
+3. Next, call `cibuildwheel`. Unfortunately, MSVC has separate toolchains for compiling 32-bit and 64-bit, so you will need to run `cibuildwheel` twice: once with `CIBW_BUILD=*-win32` after setting up the `x86` build environment, and once with `CIBW_BUILD=*-win_amd64` in a `x64` environment (see previous step).
+
+
+**GitHub Action example with ilammy/msvc-dev-cmd**:
+
+```yaml
+  - uses: ilammy/msvc-dev-cmd@v1
+
+  - name: Build 64-bit wheel
+    run: python -m cibuildwheel --output-dir wheelhouse
+    env:
+      CIBW_BUILD: cp27-win_amd64
+      DISTUTILS_USE_SDK: 1
+      MSSdk: 1
+
+  - uses: ilammy/msvc-dev-cmd@v1
+    with:
+      arch: x86
+
+  - name: Build 32-bit wheel
+    run: python -m cibuildwheel --output-dir wheelhouse
+    env:
+      CIBW_BUILD: cp27-win32
+      DISTUTILS_USE_SDK: 1
+      MSSdk: 1
+```

+### Semi-automatic method using wheelhouse-uploader
 
-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
-version and tag it.
+Obviously, manual steps are for chumps, so we can automate this a little by using [wheelhouse-uploader](https://github.com/ogrisel/wheelhouse-uploader).
 
-### Generic instructions
+> Quick note from me - using S3 as a storage didn't work due to a [bug](https://issues.apache.org/jira/browse/LIBCLOUD-792) in libcloud. Feel free to use my fork of that package that fixes the bug `pip install https://github.com/joerick/libcloud/archive/v1.5.0-s3fix.zip`
 
-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".
+### Automatic method
 
-### GitHub Actions
+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. This doesn't require anycloud storage to work - you just need to bump the version and tag it.
 
-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:
-
-```yaml
-  make_sdist:
-    name: Make SDist
-    runs-on: ubuntu-latest
-    steps:
-    - uses: actions/checkout@v4
-      with:
-        fetch-depth: 0  # Optional, use if you use setuptools_scm
-        submodules: true  # Optional, use if you have submodules
-
-    - name: Build SDist
-      run: pipx run build --sdist
-
-    - uses: actions/upload-artifact@v4
-      with:
-        name: cibw-sdist
-        path: dist/*.tar.gz
-```
-
-Then, you need to publish the artifacts that the previous jobs have built. This final job should run only on release or tag, depending on your preference. It gathers the artifacts from the sdist and wheel jobs and uploads them to PyPI. The release environment (`pypi` in the example below) will be created the first time this workflow runs.
-
-This requires setting this GitHub workflow in your project's PyPI settings (for a [new project](https://docs.pypi.org/trusted-publishers/creating-a-project-through-oidc)/[existing project](https://docs.pypi.org/trusted-publishers/adding-a-publisher)).
-
-```yaml
-  upload_all:
-    needs: [build_wheels, make_sdist]
-    environment: pypi
-    permissions:
-      id-token: write
-    runs-on: ubuntu-latest
-    if: github.event_name == 'release' && github.event.action == 'published'
-    steps:
-    - uses: actions/download-artifact@v4
-      with:
-        pattern: cibw-*
-        path: dist
-        merge-multiple: true
-
-    - uses: pypa/gh-action-pypi-publish@release/v1
-```
-
-You should use Dependabot to keep the publish action up to date. In the above
-example, the same name (the default, "artifact" is used for all upload-artifact
-runs, so we can just download all of the in one step into a common directory.
-
-See
-[`examples/github-deploy.yml`](https://github.com/pypa/cibuildwheel/blob/main/examples/github-deploy.yml)
-for an example configuration that automatically upload wheels to PyPI. Also see

-### TravisCI
-
-See
-[`examples/travis-ci-deploy.yml`](https://github.com/pypa/cibuildwheel/blob/main/examples/travis-ci-deploy.yml)
-for an example configuration.
+[`examples/travis-ci-deploy.yml`](https://github.com/pypa/cibuildwheel/blob/master/examples/travis-ci-deploy.yml) and [`examples/github-deploy.yml`](https://github.com/pypa/cibuildwheel/blob/master/examples/github-deploy.yml) are example configurations that automatically upload wheels to PyPI. Also check out [this example repo](https://github.com/pypa/cibuildwheel-autopypi-example) for more detailed instructions on how to set this up.

-# Tips and tricks
+### Troubleshooting
 
-## Tips
+If your wheel didn't compile, check the list below for some debugging tips.
 
-### Linux builds in containers
+- A mistake in your config. To quickly test your config without doing a git push and waiting for your code to build on CI, you can test the Linux build in a Docker container. On Mac or Linux, with Docker running, try `cibuildwheel --platform linux`. You'll have to bring your config into the current environment first.
 
-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:
+- Missing dependency. You might need to install something on the build machine. You can do this in `.travis.yml`, `appveyor.yml`, or `.circleci/config.yml`, with apt-get, brew or choco. Given how the Linux build works, you'll need to use the [`CIBW_BEFORE_BUILD`](options.md#before-build) option.
 
--   Programs and libraries are not installed on the CI runner host, but rather should be installed inside the container - using `yum` for `manylinux2010` or `manylinux2014`, `apt-get` for `manylinux_2_24`, `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.
+- Windows: missing C feature. The Windows C compiler doesn't support C language features invented after 1990, so you'll have to backport your C code to C90. For me, this mostly involved putting my variable declarations at the top of the function like an animal.
 
-    `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.
+- MacOS: calling cibuildwheel from a python3 script and getting a `ModuleNotFoundError`? Due to a (fixed) [bug](https://bugs.python.org/issue22490) in CPython, you'll need to [unset the `__PYVENV_LAUNCHER__` variable](https://github.com/pypa/cibuildwheel/issues/133#issuecomment-478288597) before activating a venv.
 
--   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.
+### Linux builds on Docker
 
--   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.

See [options](options.md#manylinux-image) for more details.

+most packages should provide both `x86_64` and `universal2` wheels for now.
+Once Pip 20.3+ is common on macOS, then it should be possible to ship only the

-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.
+**Apple Silicon wheels are not built by default**, but can be enabled by adding extra archs to the [`CIBW_ARCHS_MACOS` option](options.md#archs) - e.g. `x86_64 arm64 universal2`. Cross-compilation is provided by the Xcode toolchain.
 
-See [GitHub issue 1333](https://github.com/pypa/cibuildwheel/issues/1333) for more discussion.
+!!! important
+    When cross-compiling on Intel, it is not possible to test `arm64` and the `arm64` part of a `universal2` wheel.
 
-#### How?
+    `cibuildwheel` will raise a warning to notify you of this - these warnings be be silenced by skipping testing on these platforms: `CIBW_TEST_SKIP: *_arm64 *_universal2:arm64`.
 
-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"`.
+Hopefully, cross-compilation is a temporary situation. Once we have widely
+available Apple Silicon CI runners, we can build and test `arm64` and
+`universal2` wheels natively. That's why `universal2` wheels are not yet built
+by default, and require opt-in by setting `CIBW_ARCHS_MACOS`.
 
 !!! 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`.
+    Your runner needs Xcode Command Line Tools 12.2 or later to build `universal2` or `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`.

+`cibuildwheel` supports cross-compiling `universal2` and `arm64` wheels on `x86_64` runners.
 
-To create a package that builds ABI3 wheels, you'll need to configure your build backend to compile libraries correctly create wheels with the right tags. [Check this repo](https://github.com/joerick/python-abi3-package-sample) for an example of how to do this with setuptools.
+These wheels are not built by default, but can be enabled by setting the [`CIBW_ARCHS_MACOS` option](options.md#archs) to `x86_64 arm64 universal2`. Cross-compilation is provided by the Xcode toolchain.
 
-You could also consider running [abi3audit](https://github.com/trailofbits/abi3audit) against the produced wheels in order to check for abi3 violations or inconsistencies. You can run it alongside the default in your [CIBW_REPAIR_WHEEL_COMMAND](options.md#repair-wheel-command).

+    Your runner image needs Xcode Command Line Tools 12.2 or later to build `universal2` and `arm64`.
+
+    So far, only CPython 3.9 supports `universal2` and `arm64` wheels.
+
+Here's an example GitHub Actions workflow with a job that builds for Apple Silicon:
+
+> .github/workflows/build_macos.yml
+
+```yml

+```
+
+### Windows and Python 2.7
+
+Building 2.7 extensions on Windows is difficult, because the VS 2008 compiler that was used for the original Python compilation was discontinued in 2018, and has since been removed from Microsoft's downloads. Most people choose to not build Windows 2.7 wheels, or to override the compiler to something more modern.
+
+To override, you need to have a modern compiler toolchain activated, and set `DISTUTILS_USE_SDK=1` and `MSSdk=1`. For example, on GitHub Actions, you would add these steps:
+
+```yaml
+    - name: Prepare compiler environment for Windows
+      if: runner.os == 'Windows'
+      uses: ilammy/msvc-dev-cmd@v1
+      with:
+        arch: x64
+
+    - name: Set Windows environment variables
+      if: runner.os == 'Windows'
+      shell: bash
+      run: |
+        echo "DISTUTILS_USE_SDK=1" >> $GITHUB_ENV
+        echo "MSSdk=1" >> $GITHUB_ENV
+
+    # invoke cibuildwheel...
+```
+
+cibuildwheel will not try to build 2.7 on Windows unless it detects that the above two variables are set. Note that changing to a more modern compiler will mean your wheel picks up a runtime dependency to a different [Visual C++ Redistributable][]. You also need to be [a bit careful][] in designing your extension; some major binding tools like pybind11 do this for you.

-### Automatic updates using Dependabot {: #automatic-updates}
-
-Selecting a moving target (like the latest release) is generally a bad idea in CI. If something breaks, you can't tell whether it was your code or an upstream update that caused the breakage, and in a worse-case scenario, it could occur during a release.
-
-There are two suggested methods for keeping cibuildwheel up to date that instead involve scheduled pull requests using GitHub's Dependabot.
-
-#### Option 1: GitHub Action
-
-If you use GitHub Actions for builds, you can use cibuildwheel as an action:
-
-```yaml
-uses: pypa/cibuildwheel@v2.21.3
-```
-
-This is a composite step that just runs cibuildwheel using pipx. You can set command-line options as `with:` parameters, and use `env:` as normal.
-
-Then, your `.github/dependabot.yml` file could look like this:
-
-```yaml
-version: 2
-updates:
-  - package-ecosystem: "github-actions"
-    directory: "/"
-    schedule:
-      interval: "weekly"
-```
-
-#### Option 2: Requirement files
-
-The second option, and the only one that supports other CI systems, is using a `requirements-*.txt` file. The file should have a distinct name and have only one entry:
-
-```bash
-# requirements-cibw.txt
-cibuildwheel==2.21.3
-```
-
-Then your install step would have `python -m pip install -r requirements-cibw.txt` in it. Your `.github/dependabot.yml` file could look like this:
-
-```yaml
-version: 2
-updates:
-  - package-ecosystem: "pip"
-    directory: "/"
-    schedule:
-      interval: "daily"
-```
-
-This will also try to update other pins in all requirement files, so be sure you want to do that. The only control you have over the files used is via the directory option.
-
-
-### Alternatives to cibuildwheel options {: #cibw-options-alternatives}
-
-cibuildwheel provides lots of opportunities to configure the build
-environment. However, you  might consider adding this build configuration into
-the package itself - in general, this is preferred, because users of your
-package 'sdist' will also benefit.
-
-#### Missing build dependencies {: #cibw-options-alternatives-deps}
-
-If your build needs Python dependencies, rather than using `CIBW_BEFORE_BUILD`, it's best to add these to the
-[`build-system.requires`](https://www.python.org/dev/peps/pep-0518/#build-system-table)
-section of your pyproject.toml. For example, if your project requires Cython
-to build, your pyproject.toml might include a section like this:
-
-```toml
-[build-system]
-requires = [
-    "setuptools>=42",
-    "Cython",
-]
-
-build-backend = "setuptools.build_meta"
-```
-
-#### Actions you need to perform before building
-
-You might need to run some other commands before building, like running a
-script that performs codegen or downloading some data that's not stored in
-your source tree.
-
-Rather than using `CIBW_BEFORE_ALL` or `CIBW_BEFORE_BUILD`, you could incorporate
-these steps into your package's build process. For example, if you're using
-setuptools, you can add steps to your package's `setup.py` using a structure
-like this:
-
-```python
-import subprocess
-import setuptools
-import setuptools.command.build_py
-
-
-class BuildPyCommand(setuptools.command.build_py.build_py):
-    """Custom build command."""
-
-    def run(self):
-        # your custom build steps here
-        # e.g.
-        #   subprocess.run(['python', 'scripts/my_custom_script.py'], check=True)
-        setuptools.command.build_py.build_py.run(self)
-
-
-setuptools.setup(
-    cmdclass={
-        'build_py': BuildPyCommand,
-    },
-    # Usual setup() args.
-    # ...
-)
-```
-
-#### Compiler flags
-
-Your build might need some compiler flags to be set through environment variables.
-Consider incorporating these into your package, for example, in `setup.py` using [`extra_compile_args` or
-`extra_link_args`](https://docs.python.org/3/distutils/setupscript.html#other-options).
-
-### Python 2.7 / PyPy2 wheels
-
-See the [cibuildwheel version 1 docs](https://cibuildwheel.pypa.io/en/1.x/) for information about building Python 2.7 or PyPy2 wheels. There are lots of tricks and workaround there that are no longer required for Python 3 in cibuildwheel 2.
-
-## Troubleshooting
-
-If your wheel didn't compile, you might have a mistake in your config.
-
-To quickly test your config without doing a git push and waiting for your code to build on CI, you can [test the Linux build in a local Docker container](setup.md#local).
-
-### Missing dependencies
-
-Sometimes a build will fail due to a missing dependency.
-
-**If the build is missing a Python package**, you should [add it to pyproject.toml](#cibw-options-alternatives-deps).
-
-**If you need a build tool** (e.g. cmake, automake, ninja), you can install it through a package manager like apt/yum, brew or choco, using the [`CIBW_BEFORE_ALL`](options.md#before-all) option.
-
-**If your build is linking into a native library dependency**, you can build/install that in [`CIBW_BEFORE_ALL`](options.md#before-all). However, on Linux, Mac (and Windows if you're using [delvewheel]), the library that you install will be bundled into the wheel in the [repair step]. So take care to ensure that
-
-- the bundled library doesn't accidentally increase the minimum system requirements (such as the minimum macOS version)
-- the bundled library matches the architecture of the wheel you're building when cross-compiling
-
-This is particularly an issue on macOS, where de facto package manager Homebrew will install libraries that are compiled for the specific version of macOS that the build machine is running, rendering the wheels useless for any previous version. And brew will not install the right arch for cross compilation of Apple Silicon wheels.
-
-For these reasons, it's strongly recommended to not use brew for native library dependencies. Instead, we recommend compiling the library yourself. If you compile in the [`CIBW_BEFORE_ALL`](options.md#before-all) step, cibuildwheel will have already set the appropriate `MACOSX_DEPLOYMENT_TARGET` env var, so the library will target the correct version of macOS.
-
-!!! tip
-    For build steps, Homebrew is still a great resource - you can [look up the build formula](https://formulae.brew.sh/) and use that as a starting point.

-### Building Rust wheels
-
-If you build Rust wheels, you need to download the Rust compilers in manylinux.
-If you support 32-bit Windows, you need to add this as a potential target. You
-can do this on GitHub Actions, for example, with:
-
-```yaml
-CIBW_BEFORE_ALL_LINUX: curl -sSf https://sh.rustup.rs | sh -s -- -y
-CIBW_BEFORE_ALL_WINDOWS: rustup target add i686-pc-windows-msvc
-CIBW_ENVIRONMENT_LINUX: "PATH=$HOME/.cargo/bin:$PATH"
-```
-
-Rust does not provide Cargo for musllinux 32-bit, so that needs to be skipped:
-
-```toml
-[tool.cibuildwheel]
-skip = ["*-musllinux_i686"]
-```
-
-Also see [maturin-action](https://github.com/PyO3/maturin-action) which is optimized for Rust wheels, builds the non-Python Rust modules once, and can cross-compile (and can build 32-bit musl, for example).

-### macOS: Passing DYLD_LIBRARY_PATH to delocate
+### 'ImportError: DLL load failed: The specific module could not be found' error on Windows
 
-macOS has built-in [System Integrity protections](https://developer.apple.com/library/archive/documentation/Security/Conceptual/System_Integrity_Protection_Guide/RuntimeProtections/RuntimeProtections.html) which limits the use of `DYLD_LIBRARY_PATH` and `LD_LIBRARY_PATH` so that it does not automatically pass to children processes. This means if you set `DYLD_LIBRARY_PATH` before running cibuildwheel, or even set it in `CIBW_ENVIRONMENT`, it will be stripped out of the environment before delocate is called.
+Visual Studio and MSVC link the compiled binary wheels to the Microsoft Visual C++ Runtime. Normally, these are included with Python, but when compiling with a newer version of Visual Studio, it is possible users will run into problems on systems that do not have these runtime libraries installed. The solution is to ask users to download the corresponding Visual C++ Redistributable from the [Microsoft website](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) and install it. Since a Python installation normally includes these VC++ Redistributable files for [the version of the MSVC compiler used to compile Python](https://wiki.python.org/moin/WindowsCompilers), this is typically only a problem when compiling a Python 2.7 C extension with a newer compiler, e.g. to support a modern C++ standard (see [the section on modern C++ standards for Python 2.7](cpp_standards.md#windows-and-python-27) for more details).
 
-To work around this, use a different environment variable such as `REPAIR_LIBRARY_PATH` to store the library path, and set `DYLD_LIBRARY_PATH` in [`CIBW_REPAIR_WHEEL_COMMAND_MACOS`](https://cibuildwheel.pypa.io/en/stable/options/#repair-wheel-command), like this:
-
-!!! tab examples "Environment variables"

-### macOS: Building CPython 3.8 wheels on arm64
-
-If you're building on an arm64 runner, you might notice something strange about CPython 3.8 - unlike Python 3.9+, it's cross-compiled to arm64 from an x86_64 version of Python running under Rosetta emulation. This is because (despite the prevalence of arm64 versions of Python 3.8 from Apple and Homebrew) there is no officially supported Python.org installer of Python 3.8 for arm64.
-
-This is fine for simple C extensions, but for more complicated builds on arm64 it becomes an issue.
-
-So, if you want to build macOS arm64 wheels on an arm64 runner (e.g., `macos-14`) on Python 3.8, before invoking cibuildwheel, you should install a native arm64 Python 3.8 interpreter on the runner:
-
-
-!!! tab "GitHub Actions"
-
-    ```yaml
-    - uses: actions/setup-python@v5
-      with:
-        python-version: 3.8
-      if: runner.os == 'macOS' && runner.arch == 'ARM64'
-    ```
-
-!!! tab "Generic"
-
-    ```bash
-    curl -o /tmp/Python38.pkg https://www.python.org/ftp/python/3.8.10/python-3.8.10-macos11.pkg
-    sudo installer -pkg /tmp/Python38.pkg -target /
-    sh "/Applications/Python 3.8/Install Certificates.command"
-    ```
-
-Then cibuildwheel will detect that it's installed and use it instead. However, you probably don't want to build x86_64 wheels on this Python, unless you're happy with them only supporting macOS 11+.
-
-### macOS: Library dependencies do not satisfy target MacOS
-
-Since delocate 0.11.0 there is added verification that the library binary dependencies match the target macOS version. This is to prevent the situation where a wheel platform tag is lower than the actual minimum macOS version required by the library. To resolve this error you need to build the library to the same macOS version as the target wheel (for example using `MACOSX_DEPLOYMENT_TARGET` environment variable).
-Alternatively, you could set `MACOSX_DEPLOYMENT_TARGET` in `CIBW_ENVIRONMENT` to correctly label the wheel as incompatible with older macOS versions.
-
-This error may happen when you install a library using a package manager like Homebrew, which compiles the library for the macOS version of the build machine. This is not suitable for wheels, as the library will only work on the same macOS version as the build machine. You should compile the library yourself, or use a precompiled binary that matches the target macOS version.
-
-### Windows: 'ImportError: DLL load failed: The specific module could not be found'
-
-Visual Studio and MSVC link the compiled binary wheels to the Microsoft Visual C++ Runtime. Normally, the C parts of the runtime are included with Python, but the C++ components are not. When compiling modules using C++, it is possible users will run into problems on systems that do not have the full set of runtime libraries installed. The solution is to ask users to download the corresponding Visual C++ Redistributable from the [Microsoft website](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads) and install it.
-
-Additionally, Visual Studio 2019 started linking to an even newer DLL, `VCRUNTIME140_1.dll`, besides the `VCRUNTIME140.dll` that is included with recent Python versions (starting from Python 3.5; see [here](https://wiki.python.org/moin/WindowsCompilers) for more details on the corresponding Visual Studio & MSVC versions used to compile the different Python versions). To avoid this extra dependency on `VCRUNTIME140_1.dll`, the [`/d2FH4-` flag](https://devblogs.microsoft.com/cppblog/making-cpp-exception-handling-smaller-x64/) can be added to the MSVC invocations (check out [this issue](https://github.com/pypa/cibuildwheel/issues/423) for details and references). CPython 3.8.3 and all versions after it have this extra DLL, so it is only needed for 3.8 and earlier.
