'manylinux' Docker images are used to build Python extension modules compatible with many popular Linux distributions. This repository builds several dependencies on top of the standard manylinux images, for use in building Cantera.

Images are published on the GitHub container registry:

• cantera-base-manylinux_2_28-x86_64
• cantera-base-manylinux_2_28-aarch64

To build an image locally for testing you need to specify two build arguments for Docker:

• TARGET_ARCH: One of the supported architectures for manylinux images
  • x86_64
  • aarch64
  • s390x
  • ppc64le
• MANYLINUX_TAG: A tag in the Quay repository: https://quay.io/organization/pypa

The images are currently based on manylinux_2_28, which includes version 2.28 of glibc per PEP 600. This means that wheels built with manylinux_2_28 will work on any Linux distribution that ships glibc 2.28 or newer. The upstream manylinux project README has a good summary of compatibility with different Linux distros.

Note: The manylinux project is working on releasing manylinux_2_34 and has images available. However, there is a problem with how the compilers are configured that will break our wheels because we install openblas with dnf. See issue pypa/manylinux#1725.
