    Hi
    I just come to follow the tutorial (https://wiki.qt.io/RaspberryPi2EGLFS) to cross-compile from an opensuse 42.1 64bits for a raspberry pi 3 and all is running BUT !
    I would like to use in my application the webview component and i can't.
    I tried to compile qtwebengine but i have error.
    I understood that it was necessary to first compile qtdeclarative and it's done.
    when i make i have this error :

    make

    Hi Trom,

    there was a patch to make chromium compile with clang supporting different assembler instructions. A bad but working hack is to change all occurrences of ldrhcs to ldrcsh in qt5/qtwebengine/src/3rdparty/chromium/third_party/ffmpeg/libavcodec/arm/vp56_arith.h. Also if you like to use pepper plugins (for example you can extract a recent flash pepper plugin from a chromebook arm image) change enable_plugins=1 in qt5/qtwebengine/src/core/config/embedded_linux.pri
