Hello,
following the steps in the concentratod repository I find this:

I think that instructions maybe aims to cross-compiling on Intel base linux system (x86_64-unknown-linux-musl). On the Intel base linux can cross-compile binaries that can be run in arm64 cpu architecture (I.E Raspberry 4,5).

Instead make command try following:

cross build --target aarch64-unknown-linux-musl --release

Does it compiles now?

Compiled binary can be run in rpi5 + Docker if you use Alpine linux container (aarch64-unknown-linux-musl) in docker.

I tested this case and it not compiles on RPi (arm64) systems. You should do the compilation on Intel linux PC or WSL environment in Windows.

Following works on intel PC where I run linux (ubuntu 22.04)

$ git clone  https://github.com/chirpstack/chirpstack-concentratord.git
$ cd chirpstack-concentratord
$ nix-shell
$ make build-aarch64-unknown-linux-musl

Concentratord code compiles nicely and aarch64-unknown-linux-musl binary found in target/aarch64-unknown-linux-musl/release/ folder.
