A glibc binary package builder in Docker. Produces a glibc binary package that can be imported into a rootfs to run applications dynamically linked against glibc.
Build a glibc package based on version 2.37 with a prefix of /usr/glibc-compat:
docker run --rm --env STDOUT=1 sgerrand/glibc-builder 2.37 /usr/glibc-compat > glibc-bin.tar.gz
You can also keep the container around and copy out the resulting file:
docker run --name glibc-binary sgerrand/glibc-builder 2.37 /usr/glibc-compat
docker cp glibc-binary:/glibc-bin-2.37.tar.gz ./
docker rm glibc-binary
