Cross-compiling Rust for Pinephone [aarch64-unknown-linux-gnu]

Hello,
I am trying to cross-compile the examples from the Relm crate. I got the gcc cross-compiler and added the target via rustup

sudo pacman -S aarch64-linux-gnu-gcc
rustup target add aarch64-unknown-linux-gnu

Compiling the hello world example and running it on the Pinephone worked like a charm. When I try to compile the examples of the Relm crate with
PKG_CONFIG_ALLOW_CROSS=1 cargo build --examples --target=aarch64-unknown-linux-gnu
I get multiple errors

How can I get it to cross-compile?
Thank you for your help

Re: Cross-compiling Rust for Pinephone [aarch64-unknown-linux-gnu]

Hi,
you need to add the missing libraries. Usually this can be done by installing a package that provides these libraries. Unfortunately aarch64-linux-gnu-gtk3 is not available in the repos. I am trying to publish it to the AUR but I am a beginner myself so it might take a long time. In the meantime check out the solution in this thread at the Pinephone Forum.

Re: Cross-compiling Rust for Pinephone [aarch64-unknown-linux-gnu]

(Relm's author here.)

I just got my PinePhone and wanted to play with that as well .

I wrote a draft tutorial explaining the steps I found to fix this issue.
Use at your own risk, though, because that might mess up with your installed pacman files if I forgot something.

I also posted the instructions here to see if they can be improved.

Good luck and have fun!
