To build QtCharts calling qmake CONFIG+=debug_and_release make debug make release make install should be enough to build and install it

@BruceNaylor Hmm that's interesting! I posted on the C++ Gurus forum and a couple guys there suggested I use the MinGW that gets installed with QT Creator (when you select that option) and that actually fixed my issue with registry keys. I was going to give cross compiling another try on Windows, maybe your fudges will fix some other issues I've into. I appreciate the suggestions!

Yeah, I have right. I copy all Qt library to RPI and use this in rpi terminal: export LD_LIBRARY_PATH="/home/pi/QtBase-5.7.0/lib" ./Test and everything work. Tomorrow I'll try just install qt in rpi, and this should work without terminal. Another topic solved.
