Build

Supported Platforms

  • macOS
  • Windows

Setup

Prerequisites

  • CMake 3.15 or above
  • macOS
    • Xcode
    • Ninja (optional)
  • Windows
    • Visual Studio 2022
    • Git Bash

Initialize

Clone this repo and run the following script to initialize the submodules and download DDSP models.

./repo-init.sh

macOS

  • Generate Xcode project files (recommended for development and debugging):
    • cmake -B build -S . -G Xcode
    • Open DDSP.xcodeproj, select a target and build.
  • For release, we recommend building with Ninja or CMake since building XNNPACK is unsupported on Xcode. Additionally, Ninja builds are faster compared to CMake.
    • cmake -B build-ninja -S . -G Ninja
    • Build all targets: cmake --build build-ninja
  • Plugins will be copied to ~/Library/Audio/Plug-Ins directory automatically post-build.

Windows

  • Generate Visual Studio 2022 solution:
    • cmake -B build -G "Visual Studio 17 2022"
  • CMake adds m.lib as a dependency which causes a build error, this can be removed by running the following script after generating build files.
    • ./scripts/remove-m-lib-win.sh
  • You may encounter errors when building TFLite, they can be fixed by applying this patch.
  • Build the VST3 targets and copy plugin binaries to C:\Program Files\Common Files\VST3
  • If the plugin UI looks blurred on Ableton, right click on the plug-in title bar and deselect "Auto-Scale Plugin Window". More information can be found here

CMake

  • Edit cmake/FileList.cmake to add new source files to the project.
  • Compiler/linker options and project version can be found in cmake/Config.cmake.
