Full Log:

https://pastebin.com/yU2UTiK1

Environment:

  • OS: Ubuntu 22.04 LTS
  • Platform: VirtualBox (8GB RAM and 50GB disk space. Dont worry about the platform!)
  • Language: Chinese
  • Installed packages: crossbuild-essential-armhf, libasound2-dev:armhf(and other dependencies)
  • Target Platform: Nokia 800 Tough (KaiOS 2.5.x Linux3.10 Alsa-Supported Busybox-Supported Root-Supported NO-glibc-supported)
  • Target on cargo --target: arm-unknown-linux-musleabihf (must using musl because using guneabihf cant run on target device. )

Action that I did:

  1. Install the rustup with the Chinese mirror server (run as root):
export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup
curl --proto '=https' --tlsv1.3 https://sh.rustup.rs -sSf | sh

  1. Downloaded the musl compilation toolchain from musl.cc, version cross arm-linux-musleabihf, and added the toolchain path to the PATH:
    https://musl.cc/arm-linux-musleabihf-cross.tgz
    PATH is: /opt/arm-linux-musleabihf/bin

  2. Add armhf support to dpkg and change armhf software source to "China Tsinghua University open source software mirror":

  1. Install crossbuild-essential-armhf, libasound2-dev:armhf(run as root):
apt update
apt install crossbuild-essential-armhf libasound2-dev:armhf
  1. cargo build
  2. Error.

Additional context
The dockerfile provided by repo does not compile to musl. my attempts to use rust-musl-cross and install the environment manually also failed, so I tried to compile it manually myself instead of docker, if you have any good ideas please let me know. I will try to compile on Pi4 on July 4, 2023 at +8 PM GMT.

So your compilation fails when linking with libasound. In my experience, linking to system binaries is the most painful thing when cross-compiling rust. As a workaround/test you could try adding the flag --no-default-features to cargo build so that the default audio backend rodio-backend doesn't get compiled. Then you would only have a stdout/pipe audio device which you propably could just pipe to aplay.

Hello @BliemHax, if you are still interested, this might be of some help: #1263
What makes it work is using ubuntu 18.04 and fixing C/openssl/sound library links.
