An operating system
Bug is a Qt Creator project. In order to build it, qmake (or Qt Creator) must be available. Several other tools, such as cross compilers and x86 emulators are required as well. On a Debian-based distro, scripts/install-build-tools.sh is provided to install all the required build tools for building Bug OS.
Once installed, simply opening Bug.pro within Qt Creator and building the project is enough.
Running an OS requires a special execution environment, i.e. an emulator such as QEMU. Unfortunately, special run configurations can't be stored in a shared config file. In order to run the project from Qt Creator (by pressing the green button) a new configuration has to be created. This is done by going to Projects -> Desktop (Run) -> Run -> Add, and specifying the following as the executable:
%{sourceDir}/scripts/run-qemu.sh
