Cannot build for raspbian (Raspberry Pi 3B+) about monolith

[snshn]

Hi Samuel,
I'm trying to figure out what's causing this, have a spare RPi 3B+ to reproduce the error. Thank you for reporting this.

Awesome! Thank you. I'm pretty new to Rust/Cargo but let me know if I can do anything to help.

Hi there Samuel,

I was able to build monolith from the master branch on raspbian with no errors. I used rustup and had to install libssl-dev.
The error that you're getting is likely related to some sort of network issue when cargo tries to retrieve the needed crate. I found a couple of similar issues for other rust projects and that's what people seem to suspect regarding this kind of errors, balena-os/balena-raspberrypi#261

You could also try doing something like mv Cargo.lock Cargo.lock.bak and trying to build again, maybe it's some sort of issue caused by package versions

I'm encountering the same issue.

I was able to cross-compile monolith on my Ubuntu machine using Cargo's built-in cross-compilation functionality:

rustup target add arm-unknown-linux-gnueabihf
git clone https://github.com/raspberrypi/tools.git rpi_tools
RUSTFLAGS="-C linker=rpi_tools/arm-bcm2708/arm-rpi-4.9.3-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc" cargo build --release --target=arm-unknown-linux-gnueabihf
target/arm-unknown-linux-gnueabihf/release/monolith -V

Could you please let me know if you're able to run the binary compiled that way on your Pi? If so, I'll include that into the CI/CD pipeline to release RPi artifacts along with Windows builds.

[snshn]

The latest release includes a prebuilt binary for Raspberry Pi. I tested it on mine RPi 3B+, it works fine.

@snshn Can you also make the pipeline build and upload an x86_64/AMD64 executable with every new release?

[snshn]

Will do!

@snshn Thanks! I'd love to add support for monolith in ginstall.sh once that's done.
