I've finally mangaged to get Qt5.7 on a Raspberry Pi3, and have built an example which runs on the Pi, this was done by carefully following:
Step by Step instructions on how to install Qt5.6 on Raspberry Pi3
To get 5.7 on the Pi simply replace:
git clone git://code.qt.io/qt/qtbase.git -b 5.6
With:
git clone git://code.qt.io/qt/qtbase.git -b 5.7
This sets-up the tool chain on a Linux host in my case Ubuntu 16.04, however it doesn't install QtCreator, I then tried installing QtCreator and messed up the build, so I had to start over.
How do I get the latest QtCreator installed on either the Ubuntu 16.04 or preferably on the Pi3 ?
