Our firmware needs quite a few dependencies to be built. This page describes the easiest way to get all those dependencies installed on a Windows machine. If you are an expert user you may also look at our dedicated page.
First, install the Msys2 building platform.
Once Msys2 has been installed, launch the Msys2 terminal application, and enter the following commands
pacman -S mingw-w64-x86_64-gcc mingw-w64-x86_64-freetype mingw-w64-x86_64-pkg-config mingw-w64-x86_64-fltk git make bison python
