This image is a little different than the other images in this repo -- it's intended to be a quick way to build manylinux wheels with the production version of the libraries for debugging and testing purposes. This is designed to work as a single Docker image that doesn't require privilege or multiple images to run.
Like the other images in this repo, it expects that there is a Pillow source directory mounted at /Pillow. Unlike the others, it puts the output files in /output. This should be mounted as a volume to the host to retrieve the finished wheel.
Setting the environment variable DEBUG=1 will create a build with
symbols for debugging with Valgrind/GDB.
The Makefile has several new commands:
- make wheel: Makes a Python 3.12 manylinux_2_28 wheel, and puts it in the ./out directory.
- make 39|310|311|312: These are specific commands to make the corresponding 3.x version in the ./out directory.
The test target here is mainly to validate the image build, it is assumed that the builds will be used for other purposes or tested in other images.
- build_depends is from our integration with OSS-Fuzz
- yum_install is syntactic sugar to make the multibuild repo work with the base manylinux wheel image, rather than with its custom set of images
