    Hi,
    sudo ./configure -prefix /usr/local/Trolltech/QtEmbedded-5.2.1 -release -shared -qt-sql-sqlite -qt-libjpeg -qt-zlib -qt-libpng -qt-freetype -no-openssl -optimized-qmake -no-nis -no-opengl -no-cups -no-xcursor -no-xrandr -no-xrender -no-xkb -no-sm -no-xinerama -no-xshape -no-separate-debug-info -xplatform linux-myplatform-g++
    ​
    The configuration result:
    Could not determine the target architecture!
    Turn on verbose messaging (-v) to see the final report.
    No QPA platform plugin enabled!
    If you really want to build without a QPA platform plugin you must pass
    -no-qpa-platform-guard to configure. Doing this will
    produce a Qt that can not run GUI applications.
    The dependencies needed for xcb to build are listed in
    src/plugins/platforms/xcb/README
    cannot generate Makefile,and build。

    the linux-myplatform-g++ directory is created by me, Inside, the qmake.conf content as below:

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

    MAKEFILE_GENERATOR = UNIX
    CONFIG += incremental gdb_dwarf_index
    QMAKE_INCREMENTAL_STYLE = sublib

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

    GCC_PREFIX=/opt/cross_compiler/arm-fsl-linux-gnueabi/bin/arm-linux

    modifications to g++.conf

    QMAKE_CC = $${GCC_PREFIX}-gcc
    QMAKE_CXX = $${GCC_PREFIX}-g++
    QMAKE_LINK = $${GCC_PREFIX}-g++
    QMAKE_LINK_SHLIB = $${GCC_PREFIX}-g++

    modifications to linux.conf

    QMAKE_AR = arm-linux-ar cqs
    QMAKE_OBJCOPY = arm-linux-objcopy
    QMAKE_NM = arm-linux-nm -P
    QMAKE_STRIP = arm-linux-strip
    load(qt_config)

    Thanks!

    Anything is possible

      What is your question? Do you really not need any GUI stuff, or maybe you only want a different platform plugin than XCB (options are: minimal, xcb, eglfs, directfb, wayland. If I recall correctly, that is)?

          So why are you disabling all XCB functionality? No wonder it is failing.

                  See "this":http://qt-project.org/forums/viewthread/27076, "that":http://qt-project.org/wiki/RaspberryPi_Beginners_guide and "that":http://qt-project.org/doc/qt-4.8/qt-embedded-crosscompiling.html. I can see some of those instructions are quite outdated (Qt 5.3 does not need any patches to be compiled on ARM), but are at least worth a try.
