Rust can create statically-compiled binaries on Linux by using musl instead of glibc, but it’s not the default like it is in Go and is as a result not quite as effortless. There are a lot of crates with native dependencies that require slight environment tweaks to work on a musl build. Go on the other hand goes to great lengths to not need to link to any C code at all, to the point of shipping its own default TLS library and cryptographic primitives.
I thought the default for both Rust and Go were to statically compile everything except the dynamic link to libc? And that you could optionally statically include musl with a bit of extra work.
I've never had to do anything unusual with building, but I thought the "almost-ststically-compiled" thing was somewhere Go and Rust were almost identical.
