    Hello,

    I have successfully been able to cross compile Qt 4.7.4, compile an application, deploy the libs and application to an arm board and get a running application.

    Now I would like to get setup for debugging when I need to. I'm trying to cross compile Qt with -debug option.

    I have a cross compiler built from Openembeded, mkspecs, and working configuration without -debug.

    The below is an example of a working configuration I can use Qt for shared libs.
    @
    ./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++
    -embedded arm -little-endian -host-big-endian
    -prefix /usr/local/qt4.7.4-arm -release -fast
    -no-exceptions -no-accessibility -no-qt3support -no-multimedia -no-audio-backend
    -no-phonon -no-phonon-backend -no-svg -no-webkit -no-script -no-cups -no-dbus
    -no-gtkstyle -no-xinerama -no-glib -nomake examples -nomake tools
    -nomake demos -nomake docs -nomake translations
    -no-gtkstyle -no-opengl
    @
    Now if i just add -debug to the above configure, configure will be successful, but make will fail with the below error.

    @
    make[1]: *** [.uic/debug-shared-emb-arm/ui_qpagesetupwidget.h] Segmentation fault
    make[1]: *** Deleting file .uic/debug-shared-emb-arm/ui_qpagesetupwidget.h' make[1]: *** Waiting for unfinished jobs.... make[1]: Leaving directory /home/btl/build/cross/qt4.7.4/qt-everywhere-opensource-src-4.7.4/src/gui'
    make: *** [sub-gui-make_default-ordered] Error 2
    @

    Any suggestions work be greatly appreciated.

      What is the output before that? What is it doing when it segfaults on .uic/debug...?

        Thanks for the response Tobias,
        Here a little more of the make output. Let me know if there is any more information I can collect.

          It appears i was able to resolve this. I built a toolchain from Openembedded using uclibc instead of eglibc.

            Hi blaroche,

            Can you show the steps and configuration to compile arm-qt?
            Is there a change qmake.conf, change the library on the arm module and the compiler (ex:linux mode)?

            I am interested to compile arm-QT but I still nubie with this arm module. I've managed to compile my qt sample but can not run on my arm module there appears an error message when executed.
            I use a cross compiler gcc-4.3.2-glibc-2.7 (arm-vfp-linux-gnu-g++) and Qtopia-2.2.0-FriendlyARM.
