Building from source

Cue2 targets Godot 4.7.1 Mono with a C# project (Cue2.csproj).

Typical steps​

  1. Install Godot 4.7.1 .NET build and a compatible .NET 8 SDK.
  2. Clone the application repository.
  3. Ensure platform natives are present under bin/{win64,winarm64,macos,linux64,linuxarm64}/:
    • FFmpeg shared libraries (decode)
    • RtMidi (rtmidi.dll / librtmidi.dylib / librtmidi.so)
    • Rebuild RtMidi with python tools/build-rtmidi-natives.py if those files are missing
  4. Open the project in Godot or build with dotnet build.
  5. For exports, copy natives after Godot export using tools/copy-natives-for-export.ps1 or tools/copy-natives-for-export.sh — Godot does not embed FFmpeg or RtMidi into a single binary.

See the application README and docs/export-packaging.md in the app repo for authoritative detail.
