FRUT

FRUT makes it easy to build JUCE projects using CMake instead of Projucer. It enables more flexibility in project architecture, simplified CI setup, and easier integration with other JUCE and non-JUCE projects. Converting an existing JUCE project to FRUT is easy, and you don't need to be a CMake expert to use it!

In short

Table of Contents

Background

JUCE comes with its own project generation tool, Projucer, which is very useful when starting a JUCE project. However, Projucer doesn't scale well when you want to make some aspects of your project configurable, when you want to add external libraries, when you want to use Continuous Integration, or when you want to manage several projects at once.

FRUT was created to overcome these limitations, while making it very easy to migrate an existing JUCE project that uses Projucer. Since FRUT is based on CMake, you also get access to many great features of CMake, including testing and packaging utilities.

Contents

FRUT currently contains:

Requirements

  • CMake, version 3.4 minimum

Documentation

You can read the documentation of FRUT on Read the Docs: https://frut.readthedocs.io

Getting started

Let's consider that you have a copy of JUCE, a copy of FRUT and a JUCE project called MyGreatProject following this folder structure:

<root>
├── FRUT/
├── JUCE/
└── MyGreatProject/
    ├── Source/
    └── MyGreatProject.jucer

We first build and install FRUT with CMake:

$ cd <root>/FRUT/

$ mkdir build && cd build/

$ cmake .. -DCMAKE_INSTALL_PREFIX="../prefix" -DJUCE_ROOT="../../JUCE"
...
-- Configuring done
-- Generating done
-- Build files have been written to: <root>/FRUT/build

$ cmake --build . --target install
# or
$ cmake --build . --target install --parallel  # with CMake 3.12 or later
...

If it fails to build and install, please report the problem by creating a new issue on GitHub: https://github.com/McMartin/FRUT/issues/new.

Then we convert MyGreatProject.jucer to a new CMakeLists.txt file:

$ cd <root>/MyGreatProject/

$ ../FRUT/prefix/FRUT/bin/Jucer2CMake reprojucer MyGreatProject.jucer ../FRUT/prefix/FRUT/cmake/Reprojucer.cmake

<root>/MyGreatProject/CMakeLists.txt has been successfully generated.

Now we can build MyGreatProject using CMake:

$ cd <root>/MyGreatProject/

$ mkdir build && cd build/

$ cmake .. -G<generator>
...
-- Configuring done
-- Generating done
-- Build files have been written to: <root>/MyGreatProject/build

$ cmake --build .
# or
$ cmake --build . -- -parallelizeTargets  # when <generator> is Xcode
# or
$ cmake --build . --parallel  # with CMake 3.12 or later
...

<generator> can be one of many CMake Generators supported by your platform, including Ninja, NMake Makefiles (on Windows), Unix Makefiles (on Linux and macOS), Visual Studio 2013, 2015, 2017, 2019 and 2022 (on Windows), and Xcode (on macOS).
