Binary releases don't work with musl libc

[juliushaertl]

I was trying to get krankerl working inside of a alpine docker container. However it seems the binary is not compatible with musl libc, which is default in alpine.

Is there a way to make the binary compatible with the current build pipeline? :wink:

Good point. I think I gave this a try in the beginnings of developing this tool but I forgot if (and if not then why) it worked with musl. Let me have another look.

[ChristophWurst]

Okay, this is a bit complicated as stuff like openssl has to be compiled as well (obviously). So the simple approach like

PKG_CONFIG_ALLOW_CROSS=1 cargo build --release --target=x86_64-unknown-linux-musl

won't quite work.

https://github.com/emk/rust-musl-builder includes musl versions of openssl (and some others) to allow for easy building

Could this be reopened @ChristophWurst @icewind1991? As I tried the binary from https://github.com/ChristophWurst/krankerl/releases on alpine and it doesn't seem to work, could be resolved by https://github.com/ChristophWurst/krankerl/pull/903
