Unable to build bluster on Raspberry Pi (3B, 4)

[Jesus805]

Hi,

1. I created a new Rust project on a clean install of Raspberry Pi OS.
2. I added bluster to Cargo.toml (I tried both bluster = "0.1.2" and bluster = { git = "https://github.com/dfrankland/bluster" }
3. I get the error below when running cargo check

Am I missing any dependencies?

error: failed to run custom build command for `libdbus-sys v0.2.1`

Hi there! You may want to read through this guide here:
https://github.com/diwic/dbus-rs/blob/master/libdbus-sys/cross_compile.md

Thank you for the fast reply @dfrankland !
I'm able to build it after installing libdbus-1-dev
sudo apt-get install libdbus-1-dev
It might be useful to have this dependency in the README :)

This crate is mostly a proof of concept, so there's nary any documentation as of yet

I've been cross compiling this on a Raspberry py 3B a lot. I did have to do some work to set up a proper cross compiler using Docker: https://hub.docker.com/repository/docker/vonamos/rust_berry

I've also built a custom script for passing in some pre compile libs for DBUS. I'm happy to share with anyone interested.
