Provide static musl binaries

[dufferzafar]

Will fix issues like #74

[dufferzafar]

For me, this fails with libxcb errors, so not really a rust issue per se:

$ cargo build --release --target x86_64-unknown-linux-musl

...

   Compiling clipboard v0.5.0

I already have this in my environment though:

$ mamba env export | grep xcb

- libxcb=1.12=h87c99fc_4

FWIW, I was able to build a static musl build for myself with:

cargo build --release --target x86_64-unknown-linux-musl

From your errors above, it sounds like you're missing some libxcb libraries

FWIW, I was able to build a static musl build for myself with:

@eminence would you mind pasting the output of ldd --verbose <executable> for the executable you generated? I'd like to understand if this would work on my custom Linux distro 🙇

[eminence]

❯ ldd --verbose target/x86_64-unknown-linux-musl/release/jless
        statically linked

[pedropombeiro]

Thanks @eminence! Did you do anything special to get it to compile? I'm getting the following error:

# cargo build --release --target x86_64-unknown-linux-musl
   Compiling xcb v0.8.2
   Compiling memoffset v0.6.4
   Compiling proc-macro-error-attr v1.0.4
   Compiling cc v1.0.69

This is what I did in a ubuntu:latest Docker machine:

apt install curl git gcc libxcb1-dev libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup target add x86_64-unknown-linux-musl
git clone https://github.com/PaulJuliusMartinez/jless.git && cd jless
cargo build --release --target x86_64-unknown-linux-musl

[pedropombeiro]

Duh, I should have started with an Alpine container. But I still get an error:

error: linking with `cc` failed: exit status: 1

Unable to find build dependency python3

Did you try to install python3?

[pedropombeiro]

I was able to almost get it to work with the following flow:

apk add curl git build-base g++ libc-dev libxcb-dev
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
git clone https://github.com/PaulJuliusMartinez/jless.git && cd jless
RUSTFLAGS="-C target-feature=+crt-static"  cargo build --release --target x86_64-unknown-linux-musl

but still get linking issues:

  = note: /usr/lib/gcc/x86_64-alpine-linux-musl/12.2.1/../../../../x86_64-alpine-linux-musl/bin/ld: cannot find -lxcb: No such file or directory

oh, you probably need to be building with the patch at #121

[pedropombeiro]

I tried that and it built successfully, but the resulting executable is still dynamically linked 🤯 :

$ file target/release/jless
target/release/jless: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-musl-x86_64.so.1, with debug_info, not stripped

[eminence]

are you sure you're looking at the right binary? Normally the binary would be in ./target/x86_64-unknown-linux-musl/release/ if you're building with cargo build --release --target x86_64-unknown-linux-musl

Duh, I was so focused on fixing the build errors that I forgot that aspect. Thanks for pointing me to the right direction, it works now on the target system!

Here are the complete instructions for reference:

apk add curl git build-base g++ libc-dev libxcb-dev
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
git clone https://github.com/PaulJuliusMartinez/jless.git && cd jless
git remote add bew https://github.com/bew/jless
git fetch --all
git switch optional-clip-via-shell-cmd
git rebase origin/main
RUSTFLAGS="-C target-feature=+crt-static" cargo build --release --no-default-features --target x86_64-unknown-linux-musl

Running file on the target:

$ file target/x86_64-unknown-linux-musl/release/jless
target/x86_64-unknown-linux-musl/release/jless: ELF 64-bit LSB pie executable, x86-64, version 1 (SYSV), static-pie linked, with debug_info, not stripped
