Provide binary releases (with musl)

[dufferzafar]

Can you please provide binary releases? I saw that there's already a GitHub workflow that builds via cargo, if we could also upload the build artifacts with the releases, that would be great.

Having a library linked with musl would be great as I'd be able to run it on systems with older GLIBC.

On a sidenote, I was trying to build amp on an Ubuntu box, but since I don't have root access on the box, I can't use apt to install packages, and can only build it under a conda managed environment, which means I can only install conda packages.

Anyway, here's the error I got:

  = note: /spare/local/szafar/.conda/envs/rules-engine/bin/ld: warning: libXdmcp.so.6, needed by /usr/lib/x86_64-linux-gnu/libxcb.so, not found (try using -rpa
th or -rpath-link)

Addressing the sidenote, not the actual issue.

= note: /spare/local/szafar/.conda/envs/rules-engine/bin/ld: warning: libXdmcp.so.6, needed by /usr/lib/x86_64-linux-gnu/libxcb.so, not found (try using -rpath or -rpath-link) ... error: could not compile `amp` due to previous error

You need libXcb for the clipboard so that yanking/etc properly dispatches to the x11 clipboard. I just did a quick google, and I *believe* you can `conda install libxcb`, though I'm not too familiar with conda, so take this with a grain of salt.

@lincolnauster I'd tried installing that conda library already, and all the errors that I reported were after this.

Anyway, I was able to get a VM running Ubuntu Xenial (I'm doing all of this on a box at work, which is why all these restrictions.) I had root access on the VM so was able to install libxcb, and was able to successfully build amp YAY!

I brought the binary built on Ubuntu Xenial back to my machine which is Ubuntu Focal, and the binary worked without any issues.

BUT!

I wanted to use the same binary on remote production boxes as well (some of which are CentOS, RHEL 6 etc.)

There I get this:

❯ amp
amp: /lib64/libc.so.6: version `GLIBC_2.14' not found (required by amp)
amp: /lib64/libc.so.6: version `GLIBC_2.18' not found (required by amp)

Which is expected as well. In other rust tools, I avoid this by using a musl static build. So I tried to compile amp with musl as well, by running: cargo build --release --target x86_64-unknown-linux-musl

The build finishes successfully, no errors!

BUT!

The binary just doesn't run, not on the Xenial VM, not on my Focal box. I get the following error:

❯ target/x86_64-unknown-linux-musl/release/amp
-su: target/x86_64-unknown-linux-musl/release/amp: No such file or directory

I could be wrong, but this probably has something to do with a bad interpreter: https://www.baeldung.com/linux/bad-elf-interpreter

If anyone has any more thoughts on this, any help would be appreciated.

Similar error seen by someone else while building a musl binary: https://stackoverflow.com/questions/64849196/executing-script-with-musl-built-tclsh8-6-gives-no-such-file-or-directory

Have already tried what they did (simlinking musl libc, to the interpreter path that binary expects) but it didn't work for me.

I found a reddit thread with similar errors:
https://www.reddit.com/r/rust/comments/s1f6gu/how_to_get_rust_to_compile_an_a_purely_muslbased/

It suggested this: export RUSTFLAGS="-Clink-arg=-Wl,--dynamic-linker=/lib/ld-musl-x86_64.so.1" before running cargo build so I tried it, the build finished, but I got new errors when running the binary.
