NOTE: To build a specific version of GCS, you will need to check out the appropriate release tag. These directions are for the latest source, which may have experimental code or changes that are incompatible with the current data files. These build instructions may have also changed since a given release, so be sure to review them again with the version you plan to build.

  2. If you are building on macOS, you will also need to download and extract a copy of JDK 15 into ~/jdk-15.jdk. You can download it from here:

  3. If you are building on Windows, you'll need to install the WiX Toolset from here:

  4. Clone the source repositories:

    % git clone

    and optionally:

    % git clone
  5. Build and bundle the code for your platform:

    macOS and Linux:
