Seems you forgot to install the FrenChPP++ package. After a successful installation (you will need to compile FrenChPP++ on a standard c++ compiler if there are no binary packages for your system (we at the Unauthorized Frog recommend using g++ for this, but feel free to use clang too, but ignore the warnings)) you will need to create a new project, and just copy paste this into the newly created principal.fcpp file. Then upon execution the FrenChPP++ precompiler (which works very similarly to the way Qt handles its signals/slot mechanism) will parse all .fcpp files and will "translate" the .fcpp into valid .cpp and then compile them using your system default compiler.
