Alex Crichton a1c93a043a Lower linux glibc requirement from 2.31 to 2.28 (#575 ) In componentize-py Joel's building custom wasi-sdk binaries for more Linux compat which is what maturin, the build tool use there, desires. I don't think there's a concrete reason to have a higher Linux version here, so let's lower it in wasi-sdk itself. This commit switches the build container from Ubuntu 20.04 (glibc 2.31) to AlmaLinux 8 (glibc 2.28). The AlmaLinux container is what Wasmtime uses, for example, and has supported security updates to 2029 and is I believe intended to be used for purposes such as this.		1 month ago

About

This folder contains the docker images that are used in CI to build the wasi-sdk release toolchains. Docker is used to intentionally use older Linux distributions to build the toolchain to have a more maximal set of glibc compatibility.

These images are intended to be used on an x86_64 host. Images start from the Dockerfile.common file and then layer on target-specific toolchains/options/etc as necessary.
