# Actually Portable Executables with Cosmopolitan Libc and Rust
# Cosmopolitan Libc and Rust
> Note: the executables built using Cosmo and Rust do not work across the
> operating systems supported by Cosmopolitan Libc, because Rust decides system
> constants like `EINVAL` [at
> compile-time](https://github.com/search?q=repo%3Arust-lang%2Flibc%20EINVAL&type=code),
> based on the operating system provided in the compilation target. Thus, I
> expect the fat binaries built here will only work on `x86-64-linux` and
> `aarch64-linux`. Very well, perhaps in the future we can find a way to have
> system constants as `extern` values in Rust, like how [I did it for
> C](https://github.com/ahgamut/gcc/tree/portcosmo-11.2).
This repository contains a simple `Hello world!` example in the [Rust][rust]
programming language, that builds with [Cosmopolitan Libc][cosmo]. Now it also
