Cross compiling QT 5.5 with BBB.


  • Hi all,

    I am trying to cross compile QT 5.5 with BBB. OS Ubuntu 16.04

    this is the ./configure i have used

    ./configure -v -release -device linux-beagleboard-g++ -device-option CROSS_COMPILE=$TOOLCHAIN/home/cse/Desktop/BBB/SDK/linux-devkit/sysroots/i686-arago-linux/usr/bin/arm-linux-gnueabihf-gcc-4.7.3 -sysroot /home/cse/Desktop/BBB/SDK/Target_NFS -prefix /usr/local/qt5 -qt-xcb -qt-zlib -qt-libjpeg -qt-libpng -qt-xkbcommon -qt-freetype -qt-pcre -qt-harfbuzz -nomake examples -opengl es2

    configuration went well and i got this output

    NOTE: Qt is using double for qreal on this system. This is binary incompatible against Qt 5.1.
    Configure with '-qreal float' to create a build that is binary compatible with 5.1.

    Qt is now configured for building. Just run 'make'.
    Once everything is built, you must run 'make install'.
    Qt will be installed into /usr/local/qt5

    Prior to reconfiguration, make sure you remove any leftovers from
    the previous build.

    Now when i run "make" it is showing the following error

    .obj/qxcbmain.o: In function qt_plugin_instance': qxcbmain.cpp:(.text+0xc0): undefined reference toQPlatformIntegrationPlugin::QPlatformIntegrationPlugin(QObject*)'

    how to get rid of this error?
