    I cannot find a working toolchain to cross-compile Qt5.6 for RPi3 in a Debian environment.
    Here the official ones:

    https://github.com/raspberrypi/tools

    but they don't recognize the flags in qmake.conf of linux-rpi3-g++ mkspec.
    Which toochain should we use? I need to build all modules.

      You can follow this wiki article:
      https://wiki.qt.io/RaspberryPi2EGLFS

      Use the linux-rasp-pi2-g++ device as it works on RPi3 as well.

        @olejl77 this is the article I'm actually following! But the gcc-linaro-arm-linux-gnueabihf-raspbian doens't support ICU:

        https://github.com/raspberrypi/tools/issues/41

        and I don't understand which compiler the Qt5 stuff had in mind when wrote the linux-rpi3-g++ mkspec file because the architecture and the compiler flags are not supported!
