The source code lies and building happens inside the folder called pinballProject. For a fresh build, you need a not too old version of make, a C++ compiler (we only tested g++), a an internet connection (for downloading the Kieler Compiler), the libraries wiringPi and opencv as well as the command-line tools mega-cmd and python2. The tool for mega.nz (and also python2) can be omitted (see below on how to compile without them), everything else except for opencv comes pre-installed with Raspbian. For opencv you need a 4.x version, 4.2.0 ought to work for example. Make sure to enable the option that the entries for pkg-config get configured. It can be built from source on the Raspberry Pi in a few hours, make sure not to use too many threads for compilation because of limited RAM, also perhaps increase the swap.
