# Building Cagire

## Prerequisites

**Rust** (stable toolchain): https://rustup.rs

## System Dependencies

### macOS

```bash
brew install cmake
```

cmake is required by `rusty_link` (Ableton Link C++ bindings). Xcode Command Line Tools provide the C++ compiler. CoreAudio and CoreMIDI are built-in. The desktop build needs no additional dependencies on macOS (Cocoa/Metal are provided by the system).

### Linux (Debian/Ubuntu)

```bash
sudo apt install cmake g++ pkg-config libasound2-dev libjack-jackd2-dev
```

For the desktop build (egui/eframe), also install:

```bash
sudo apt install libgl-dev libxkbcommon-dev libx11-dev libxcursor-dev libxrandr-dev libxi-dev libwayland-dev
```

### Linux (Arch)

```bash
sudo pacman -S cmake gcc pkgconf alsa-lib jack2
```

For the desktop build:

```bash
sudo pacman -S libxkbcommon libx11 libxcursor libxrandr libxi wayland mesa
```

### Linux (Fedora)

```bash
sudo dnf install cmake gcc-c++ pkgconf-pkg-config alsa-lib-devel jack-audio-connection-kit-devel
```

For the desktop build:

```bash
sudo dnf install libxkbcommon-devel libX11-devel libXcursor-devel libXrandr-devel libXi-devel wayland-devel mesa-libGL-devel
```

### Windows

Install Visual Studio Build Tools (MSVC) and CMake. Everything else is provided by the Windows SDK.

```bash
cargo build --release
```

Desktop (egui window):

cargo build --release --features desktop --bin cagire-desktop
```

## Run

Terminal (default):

```bash
cargo run --release -- [OPTIONS]
```

Desktop (egui window):
