Compiling librespot for armv7-unknown-linux-musleabihf

[Barcol]

Has anyone compiled librespot for armv7-unknown-linux-musleabihf successfully? I cant pick a proper linker.

This is how I modified yours contrib/Dockerfile as my attempt to build it:

FROM debian:stretch

RUN dpkg --add-architecture armhf
RUN dpkg --add-architecture armel
RUN apt-get update

RUN apt-get install -y curl git build-essential crossbuild-essential-armel crossbuild-essential-armhf pkg-config gcc-arm-linux-gnueabihf
RUN apt-get install -y libasound2-dev libasound2-dev:armel libasound2-dev:armhf

RUN curl https://sh.rustup.rs -sSf | sh -s -- -y
ENV PATH="/root/.cargo/bin/:${PATH}"
RUN rustup target add arm-unknown-linux-gnueabi
RUN rustup target add arm-unknown-linux-gnueabihf
RUN rustup target add armv7-unknown-linux-musleabihf

RUN mkdir /.cargo && \
echo '[target.arm-unknown-linux-gnueabihf]\nlinker = "arm-linux-gnueabihf-gcc"' >> /.cargo/config && \
echo '[target.armv7-unknown-linux-musleabihf]\nlinker = "/src/armv7l-linux-musleabihf-cross/bin/armv7l-linux-musleabihf-gcc"' >> /.cargo/config && \. <======= This is the line I've been mostly experimenting with
echo '[target.arm-unknown-linux-gnueabi]\nlinker  = "arm-linux-gnueabi-gcc"' >> /.cargo/config

Docker build finishes flawlessly, but docker run -v /tmp/librespot-build:/build librespot-cross cargo build --release --target armv7-unknown-linux-musleabihf --no-default-features --features alsa-backend produces:

error: linking with `arm-linux-gnueabihf-gcc` failed: exit status: 1

error: could not compile `librespot` due to previous error

I don't know how to label this issue properly, as this is not a feature request, nor is it a bug report.

I believe this means you have a dependency in there somewhere for aarch64, aka armv8 or armv9. Since you are trying to compile for armv7, this dependency check fails.

Sorry I have no insight on how to fix the issue, but I believe this is the cause.
