@ruphy Call configure with additional -v option and check what exactly is the problem: most probably missing dev packages for glib and fontconfig. Same for Bluetooth support: you will need to install needed libs and headers (dev packages).

thanks for answering.
i tried some other precompiled stuff from http://www.qtrpi.com
but then i got some other error:
QML debugging is enabled. Only use this in a safe environment.
Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
QFontDatabase: Cannot find font directory /usr/local/qt5pi/lib/fonts.
Note that Qt no longer ships fonts. Deploy some (from http://dejavu-fonts.org for example) or switch to fontconfig.

now i am switched to qt 5.7.0 and i will try with qt-everywhere 5.7.0 and the following configure:
./configure -release -opengl es2 -device linux-rpi3-g++
-device-option CROSS_COMPILE=~/raspi/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian-x64/bin/arm-linux-gnueabihf-
-sysroot /home/pi/raspi/sysroot -opensource -confirm-license
-make libs -prefix /usr/local/qt5pi -extprefix /home/pi/raspi/qt5pi
-hostprefix /home/pi/raspi/qt5

let's see, if it works... i am very tired of trying :/
is there any working tutorial with qt 5.7.0 and raspberry pi 3?

[jsulm]

@ruphy So, you did not try what I suggested to find out what was missing?
If you don't resolve such issues you will not be able to cross-compile anything.
Tutorial: http://wiki.qt.io/Raspberry_Pi_Beginners_Guide

Problem solved... i took the precompiled stuff from qtrpi.com
and the video tutorial shows that i had to set2 the variables in ~/.bashrc. e.g.:
export QT_QPA_EGLFS_PHYSICAL_WIDTH=528
export QT_QPA_EGLFS_PHYSICAL_HEIGHT=295
export QT_QPA_FONTDIR=/usr/share/fonts/truetype

after closing in terminal:
source ~/.bashrc

have fun.

@jsulm one last question:
when i have qtcreator-5.7.0 than i have to take qt-everywhere 5.7.0 also?! can i use qt-everywhere5.7.1 or or qt-everywhere5.8?
thanks

[jsulm]

@ruphy There is no QtCreator 5.7. Latest QtCreator version is 4.2.2.
QtCreator can handle any QtVersion and it can handle many different versions in parallel.
