demo3

All of these demos will be preset for the raspberry 'RPI3
but can easily be changed for x86_64 changing and uncommenting one line of code
I also tried this on Manjaro archlinux RPI3

'RPI3
PRAGMA OPTIONS -Wno-write-strings -Wno-pointer-arith -I/usr/include/arm-linux-gnueabihf/qt5 -fPIC

but lets say you want to test on an x86_64
well just comment out the the PRAGMA line for the RPI3

and uncomment the x86_64 PRAGMA line

'x86_64
PRAGMA OPTIONS -Wno-write-strings -Wno-pointer-arith -Wno-deprecated -fPIC -I/usr/include/x86_64-linux-gnu/qt5 

I like archlinux Manjaro too very cutting edge software versions!
