Produce Static Binaries for Releases

[greshake]

I tried setting up static builds using Docker containers based on either Alpine and Ubuntu with musl versions of Rust. Unfortunately the builds fail because proc_macro used by serde_derive can't be used in static builds. I'm not quite sure if there will be a workaround for this.

You can try this yourself with this Dockerfile (build with docker build -t i3status-rust .):

FROM alpine:3.10

RUN echo 'http://dl-cdn.alpinelinux.org/alpine/edge/testing' >> /etc/apk/repositories

RUN apk update && \
    apk add dbus-dev pulseaudio rustup

RUN /usr/bin/rustup-init -y \
    --default-host x86_64-unknown-linux-musl \
    --default-toolchain stable

Execute this from the main repo folder to get a build:

docker run --rm -it -v "$(pwd)":/src i3status-rust sh -c 'cd src && cargo build --release'

@atheriel I saw this comment today and gave it a go - it built successfully.

Dockerfile:

FROM alpine:3.11

RUN apk update && \
    apk add dbus-dev pulseaudio build-base

RUN apk add --update-cache \
--repository https://alpine.global.ssl.fastly.net/alpine/edge/community \
rustup

RUN /usr/bin/rustup-init -y \
    --default-host x86_64-unknown-linux-musl \
    --default-toolchain stable

ENV PATH /root/.cargo/bin:$PATH

docker run --rm -it -v "$(pwd)":/src i3status-rust sh -c 'cd src && RUSTFLAGS="-C target-feature=-crt-static" cargo build --release'

Last time I gave it a go, I was able to compile, but the resulting binary wasn't executable. Maybe someone else can try?

I actually get this compile error:

Caused by:

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl

Info

• Void Linux - musl libc
• rustc - 1.50.0/1.51.0
• stable-x86_64-unknown-linux-musl
• Default compiler options

Compilation

Successful

Execution

Segfaults immediately. Some time ago I did some debugging and the segfault is caused by dbus, pulseaudio and openssl. If I remove all the blocks that require them from my config, it works.

Setting cargo config to

❯ cat .cargo/config.toml                              
[build]
rustflags = ["-C", "target-feature=-crt-static"]

makes it possible to use i3status-rust, but the binary is no longer static.

[ammgws]

Yeah I couldn't get past that either. Wonder if it's just not possible to do this with our codebase?
