Compiling soapysdr-rs

[wcampbell0x2a]

Hey! I have a project (https://github.com/rsadsb/dump1090_rs) that I want to provide a way for cross compiling the binary. This library uses https://github.com/kevinmehall/rust-soapysdr which binds to the SoapySDR project.

Dockerfile

FFROM rustembedded/cross:armv7-unknown-linux-gnueabihf
#FROM rustembedded/cross:armv7-unknown-linux-musleabihf

ENV TZ=Europe/Kiev
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone

ENV CC=armv7-unknown-linux-musleabihf-gcc
ENV AR=armv7-unknown-linux-musleabihf-ar

RUN \
    dpkg --add-architecture arm && \
    apt-get update && \
    apt-get install -y software-properties-common && \
    rm -rf /var/lib/apt/lists/*

RUN \
    add-apt-repository -y ppa:myriadrf/drivers && \
    apt-get update && \
    apt-get install -y rtl-sdr soapysdr-module-rtlsdr && \
    apt-get install -y libsoapysdr-dev

RUN \
    apt-get install -y libclang-dev llvm-dev pkg-config gcc libc6-dev

build docker

docker build -t rsadsb/armv7-unknown-linux-gnueabihf:0.1.0 ./

Cross.toml

[target.armv7-unknown-linux-gnueabihf]
image = "rsadsb/armv7-unknown-linux-gnueabihf:0.1.0"

build binary

cross build  --workspace --target armv7-unknown-linux-gnueabihf

This produces the following error:

  --- stderr
  /usr/include/SoapySDR/Config.h:51:10: fatal error: 'iso646.h' file not found
  /usr/include/SoapySDR/Config.h:51:10: fatal error: 'iso646.h' file not found, err: true

  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I don't know how to fix this, or what is wrong... Any help would be appreciated!

this seems like a bindgen issue, see #257

You'll probably need to update the clang version. Image is currently on Ubuntu 16.04, see #591 for a PR updating them

Thanks! That worked for this most part, it isn't installing the correct version of soapysdr library. Installing /x86_64-linux-gnu, I'll research more later on it, maybe i'll find something but if you already know the answer that would be awesome.

I might install soapysdr from source anyway, this is an old version. I might be able to instruct on the arch in there build scripts.

And now I see this...:

  wrapper.h:1:10: fatal error: 'stdbool.h' file not found
  wrapper.h:1:10: fatal error: 'stdbool.h' file not found, err: true

Update! Getting a new error, and it looks like something that isn't my fault ;)

Built the following MR: #591

I eventually had enough time to fix this issue, thanks for the help: rsadsb/dump1090_rs#12.
