Qt baseline app support :-P is it already there?
« on: March 01, 2019, 07:28:20 AM »
If i programm my own application, is there already a package or framework for Qt (https://www.qt.io/)

Especially on piCore i thought about using tinyCore and my selfprogrammed Application as a kiosk system that boots fast into my application.

 Maybe someone has experience already with this diy gui on tinycore (raspb. 3 as target hardware ) ::)

Hi ScaleThePoo
Qt does not appear to be there:

There are however  fltk  and  gtk.

qt is quite heavy and bloated for use on an RPi - you'd probably need to compile it yourself.

Wouldn't fltk be more suited to RPi?

fltk looks promising but the support is lesser than on qt i would say...

I have seen some examples where people run Qt projects on rpi boards, even if they are very basic it looks easyier to accomplish than any thing else.

If my application is very small the Qt runtime framework should not be too heavy, is it too big to fit in ram or on the swap?

Maybe Qt is against the concept of tinybcore linux because of size and performance? :o

You could try compiling it for yourself - see:

http://tinycorelinux.net/9.x/x86_64/tcz/src/qt-5.x/compile_qt-5.x

note that you need to use the RPi compiler flags "-march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp"
