Release a musl binary for Linux #15

Closed jsirois closed 1 year ago

The existing gnu libc binary:

$ cargo run --release -p package .
    Finished release [optimized] target(s) in 0.02s
     Running `target/release/package .`
Wrote the ptex to ./ptex-linux-x86_64
$ file ptex-linux-x86_64
ptex-linux-x86_64: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=528c3e1235c9aebdf6fc7783db656cfb5d7c61e4, for GNU/Linux 3.2.0, stripped

Vs musl:

$ cargo build --target x86_64-unknown-linux-musl --release
    Finished release [optimized] target(s) in 0.01s
$ file target/x86_64-unknown-linux-musl/release/ptex

$ ldd target/x86_64-unknown-linux-musl/release/ptex
        statically linked

The only detail to tackle is that getting the --target to stick for cargo run -p package-style builds has, so far, proved a mystery. May need to re-jigger how package works or come up with something else.
