Rust and Cosmopolitan Libc2023-11-01 Update: I found out that Rust decides system constants like EINVAL and SIGTERM at compile-time, which means that the portability of Rust executables is limited to x86_64-linux and aarch64-linux, the targets with which the executables are built. It’s good to know that Cosmo can be a viable target for Rust, and perhaps later we may use extern system constants in

Python is Actually PortableUpdate (2024-04-15): The Python executable build process described in this post is from 2021, and both Cosmopolitan Libc and the surrounding tooling have improved since 2021. The build process is much simpler now, you can download Python 3.11.4 Actually Portable Executables built via Github Actions at https://github.com/ahgamut/superconfigure – one of the Python binaries

I read the article explaining how it works, but most of it went over my head.
