Installing required packages:
sudo ./install-dependencies.sh
You then need to run the following to create the "build.ninja" file:
./configure.py
Note it is enough to run this once, and you don't need to repeat it before every build. build.ninja includes a rule which will automatically re-run ./configure.py if it changes.
Then finally:
ninja-build
In case there are compilation issues, especially like g++: internal compiler error: Killed (program cc1plus) try giving more memory to gcc, either by limiting the amount of threads ( -j1 ) and/or allowing at least 4g ram to your machine
