This repository contains CI scripts that use the cibuildwheel project to build compiled wheels for upload to PyPI, for a variety of Python versions, operating systems, and architectures.
In general, this repository does not need to be touched except for when there is a release; and then, only the environment variables in .ci/ci.yaml will need to be updated.
We use Jenkins, Azure Pipelines, and Github Actions to build all the different configurations that cibuildwheel supports. Whether it is advisable to use three different services is a question that it is not preferred to ask, for that ship has already sailed.
The Jenkins configuration is specified in Jenkinsfile, and defines all the
Linux jobs, along three axes: architecture, Python environment, and Python
version.
The entrypoint for Azure Pipelines is azure-pipelines.yml, and this has two
sets of jobs:
-
OS X: builds wheels for
x86_64andarm64 -
Windows: builds wheels for
amd64andwin32
Github Actions is used for the Windows ARM64 build; however, that build is
currently disabled, since a suitable LAPACK implementation is not available in
vcpkg.
