    Regards to all!

    I'm new in this group.

    Forgive me if suddenly a topic already seen, but I have not found an answer at all... (it's a few months that I try!).

    Is it possible to cross-compile QT5 for any version of Linux x11 with the BeagleBone?

    I want cross compile Qt for develop with QtCreator and run my application on BB (now I'm trying with debian 7.5 from "here":http://elinux.org/Beagleboard:BeagleBoneBlack_Debian).

    My best results is with bare-metal library downloaded from here":http://armsdr.blogspot.it/2014/03/qt-521-beaglebone-binaries.html
    It works perfectly, both with example that with my test application (if compiled on BB!).

    Now I'm trying to cross-compile Qt on my pc with that configuration (every following "Louis McCarthy":http://armsdr.blogspot.it/2014/01/bare-metal-qt-52-on-beaglebone-black.html beautifull tutorial!):

    @
    ../qt-everywhere-opensource-src-5.2.1/configure -v
    -sysroot /home/user/qt-5.2-target/debian-7.5
    -opensource -confirm-license
    -prefix /usr/local/qt-deb-5.2.1
    -no-largefile -no-accessibility
    -qt-zlib -no-gif -qt-libpng -qt-libjpeg -no-nis -no-cups
    -xplatform linux-linaro-gnueabihf-g++
    -device linux-beaglebone-g++
    -device-option CROSS_COMPILE=/usr/local/linaro/bin/arm-linux-gnueabihf-
    @

    If I cut -sysroot ... option I've no problem in compilation, but application can work only with linuxfb platform, not under X.
    With ".sysroot..." option (obviously the copy of my uSD file-system), configure give me that report:

    but during "make" I get this error:

    @
    /usr/local/linaro/bin/../lib/gcc/arm-linux-gnueabihf/4.7.3/../../../../arm-linux-gnueabihf/bin/ld: /home/user/qt-5.2-target/debian-7.5/usr/lib/arm-linux-gnueabihf/libm.a(mpa.o): relocation R_ARM_THM_MOVW_ABS_NC against `a local symbol' can not be used when making a shared object; recompile with -fPIC
    @

    What have I to "recompile with -fPIC" ?
    I can't figure how proceed!

    I'm sure to be closer to my goal, but...

    Thank you in advance!
