MMDVMHost-Zig

Description

This project is a Zig build system setup for MMDVMHost, a widely-used software for ham radio enthusiasts that interfaces with Multi-Mode Digital Voice Modem (MMDVM) hardware, commonly used in amateur radio digital voice systems like DMR, D-STAR, and System Fusion.

I made this because I thought it would be a good opportunity to learn about Zig and it's features, particularly how it can be used for cross-platform builds.

Building MMDVMHost with Zig

Prerequisites

Zig (version 0.11.0): The project requires Zig version 0.11.0 for the build process. Ensure you have this specific version of Zig installed or it won't work.
Thankfully dependencies are simple. The only library needed is samplerate. I've included the aarch64-linux-gnu shared object files (see project structure above). If you want to compile for a different target, just add the files to the /vendor directory.

Building

Clone the repository and initialize the submodule:

git clone https://github.com/blark/mmdvmhost-zig.git
cd mmdvmhost-zig
git submodule update --init --recursive

and then you can build with zig build or to build for aarch64 zig build -Dtarget=aarch64-linux-gnu

check ./zig-out/bin for your binaries
