QT cross compile issue on ubuntu 14.04



  • Hi,
    I am trying to cross compile QT5.6 on Ubuntu14.04(for cubieboard4).I have copied related files & library from cubieboard 4 to my usr directory & tried to compile the QT using below command,

    ./configure -xplatform linux-arm-gnueabi-g++ -opengl -verbose

    But it gives me error,

    OpenGL ES 2.0 disabled.
    All the OpenGL functionality tests failed!
    You might need to modify the include and library search paths by editing
    QMAKE_INCDIR_OPENGL, QMAKE_LIBDIR_OPENGL and QMAKE_LIBS_OPENGL in
    /home/pramodj/QT-Opensource/qt-everywhere-opensource-src-5.6.0-rc/qtbase/mkspecs/linux-arm-gnueabi-g++.

    I have also changed the path in qmake.conf file.Below is the content of qmake.conf file

    qmake configuration for building with arm-linux-gnueabi-g++

    MAKEFILE_GENERATOR = UNIX
    CONFIG += incremental
    QMAKE_INCREMENTAL_STYLE = sublib

    include(../common/linux.conf)
    include(../common/gcc-base-unix.conf)
    include(../common/g++-unix.conf)

    #include openGL libraries

    QMAKE_INCDIR_OPENGL = /usr/arm-linux-gnueabihf/include/GL
    QMAKE_LIBDIR_OPENGL = /usr/arm-linux-gnueabihf/
    QMAKE_LIBS_OPENGL = -lglut -lGLU -lGL
    QMAKE_LIBDIR_X11 = /usr/arm-linux-gnueabihf/

    modifications to g++.conf

    QMAKE_CC = arm-linux-gnueabi-gcc
    QMAKE_CXX = arm-linux-gnueabi-g++
    QMAKE_LINK = arm-linux-gnueabi-g++
    QMAKE_LINK_SHLIB = arm-linux-gnueabi-g++

    modifications to linux.conf

    QMAKE_AR = arm-linux-gnueabi-ar cqs
    QMAKE_OBJCOPY = arm-linux-gnueabi-objcopy
    QMAKE_NM = arm-linux-gnueabi-nm -P
    QMAKE_STRIP = arm-linux-gnueabi-strip

    load(qt_config)

    I am new to QT. Any help will be appreciated

    Hi,

    Where did you put the files you copied from the CubieBoard root filesystem ? Why not use the rootfs option of configure ?



  • Thanks for your reply. I have put the files in usr directory. My path is /usr/arm-linux-gnueabihf .

    You copied all the sysroot in /usr/arm-linux-gnueabihf



  • Please provide a link or document to cross compile QT.I have tried to copy sysroot in /usr/arm-linux-gnueabihf but no effect.

    A quick search with cubieboard and Qt 5 turns this

    Note that you should also contact the cubieboard community.
