Examples for sodium-cxx

Sodium-cxx is the C++ variant of the Sodium framework for Functional Reactive Programming (FRP). There is a great book Functional Reactive Programming from Stephen Blackheath and Anthony Jones, which includes many examples based on the Java variant of Sodium. This project aims to translate these examples to C++. You find the original examples in the Sodium repository.

How to build

Sodium-cxx requires Boost. E.g. on macOS you can install Boost with

brew install boost

Many of the sodium-cxx-examples require Qt. E.g. on macOS you can install Qt with

brew install qt

or you can use the official binary installers from the Qt Project.

Get, build and install sodium-cxx

git clone https://github.com/SodiumFRP/sodium-cxx.git
cmake -B sodium-cxx/build -DCMAKE_INSTALL_PREFIX="$PWD/sodium-cxx/install" -DCMAKE_BUILD_TYPE=Release -G Ninja sodium-cxx
cmake --build sodium-cxx/build
cmake --install sodium-cxx/build

If you installed Boost or Qt in a non-standard location, you need to add -DCMAKE_PREFIX_PATH="/path/to/boost;/path/to/qt" to the first cmake call.

Build the examples

cd /to/this/directory
cmake -B build -DCMAKE_PREFIX_PATH=/path/to/sodium-cxx/install -G Ninja .
cmake --build build

If you installed Boost or Qt in a non-standard location, you need to change the first cmake call to include the path to Boost or Qt -DCMAKE_PREFIX_PATH="/path/to/sodium-cxx/install;/path/to/boost;/path/to/qt" to the first cmake call.
