3 3  The source code lies and building happens inside the folder called {{code language="none"}}pinballProject{{/code}}. For a fresh build, you need a not too old version of {{code language="none"}}make{{/code}}, a C++ compiler (we only tested {{code language="none"}}g++{{/code}}), an internet connection (for downloading the Kieler Compiler), the libraries {{code language="none"}}wiringPi{{/code}} and {{code language="none"}}opencv{{/code}} as well as the command-line tools [[mega-cmd>>url:https://mega.nz/cmd||shape="rect"]] and {{code language="none"}}python2{{/code}}. The tool for mega.nz (and also {{code language="none"}}python2{{/code}}) can be omitted (see below on how to compile without them), everything else except for {{code language="none"}}opencv{{/code}} comes pre-installed with Raspbian. For {{code language="none"}}opencv{{/code}} you need a 4.x version, 4.2.0 ought to work for example. Make sure to enable the option that the entries for {{code language="none"}}pkg-config{{/code}} 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.

139 139  Working without mega.nz (and python): On the pi, you need to create a file called {{code language="none"}}_pi_logged_in{{/code}} (e.g. with {{code language="none"}}touch _pi_logged_in{{/code}}) before calling {{code language="none"}}make{{/code}} for the first time. On a different machine, you don’t need to do this. You cannot use {{code language="none"}}make capture{{/code}} or {{code language="none"}}make get{{/code}} without these command-line tools.
