    i've never tried on a 64bit machine, good suggestion, thank you.
    try this configure.
    but first, cleanup. run
    make confclean

    ./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -host-little-endian -prefix /usr/local/beaglebone/qt4.8-arm -no-cups -no-accessibility -reduce-relocations -no-nas-sound -no-sm -no-nis -qt-libjpeg -qt-libpng -qt-zlib -no-sql-ibase -no-sql-mysql -no-sql-odbc -no-sql-psql -no-sql-sqlite -no-sql-sqlite2 -no-pch -no-dbus -no-glib -no-phonon -no-phonon-backend -no-webkit -no-multimedia -no-audio-backend -no-qt3support -nomake examples -nomake demos -nomake docs -nomake translations -no-qt3support -exceptions -no-fast

    I did * make confclean* which make claimed it couldn't find any target file/config so i just did the ./configure above with the last post that includes the little-endian flag and now I recieve this error, Thanks again for the help I'm excited to get to BeagleBone programming

    Hmm... Google suggests that the "-m64" is not supported by these cross-compilers. I don't have a 64-bit machine, so I'm not sure where that is being set.

    Go to your Qt root folder and call this to find out:
    @
    grep m64 *
    @

    You might be able to manually remove the flag and continue.

    hmm. lets go back and see if we can find a smaller configure that you can build on.

    see where you get with this one:
    @./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -host-big-endian -prefix /usr/local/beaglebone/qt4.8-arm @

    then maybe try this:
    @./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -prefix /usr/local/beaglebone/qt4.8-arm @

    i'm with JSKH, i've never cross compiled on 64 bit.

    another one to try...
    @
    ./configure -v -opensource -confirm-license -xplatform qws/linux-arm-gnueabi-g++ -embedded arm -little-endian -prefix /usr/local/beaglebone/qt4.8-arm

    That first configure seems to have done the trick, This was the end result

    @
    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/beaglebone/qt4.8-arm

    To reconfigure, run 'make confclean' and 'configure'.
    @

    So i ran make and recieved the following error

    @make[1]: arm-none-linux-gnueabi-g++: Command not found
    make[1]: *** [.obj/release-shared-emb-arm/qabstractanimation.o] Error 127
    make[1]: Leaving directory `/home/xenland/qt-everywhere-opensource-src-4.8.3/src/corelib'
    make: *** [sub-corelib-make_default-ordered] Error 2    @

    Its odd that it says its trying to execute arm-none-linux-gnueabi-g++

    check your mkspecs again.
    look at this file:
    /home/xenland/qt-everywhere-opensource-src-4.8.3/mkspecs/qws/linux-arm-gnueabi-g++/qmake.conf

    you should see stuff for:
    arm-angstrom-linux-gnueabi-*
    not
    arm-none-linux-gnueabi-*

    should look like the below:
    @ #
    # qmake configuration for building with arm-none-linux-gnueabi-g++
    #

    include(../../common/linux.conf)
include(../../common/gcc-base-unix.conf)
include(../../common/g++-unix.conf)
include(../../common/qws.conf)
 
# modifications to g++.conf
QMAKE_CC                = arm-angstrom-linux-gnueabi-gcc
QMAKE_CXX               = arm-angstrom-linux-gnueabi-g++
QMAKE_LINK              = arm-angstrom-linux-gnueabi-g++
QMAKE_LINK_SHLIB        = arm-angstrom-linux-gnueabi-g++
 
 
# modifications to linux.conf
QMAKE_AR                = arm-angstrom-linux-gnueabi-ar cqs
QMAKE_OBJCOPY           = arm-angstrom-linux-gnueabi-objcopy
QMAKE_STRIP             = arm-angstrom-linux-gnueabi-strip
 
load(qt_config)

    The conf file was saying the arm-none so I changed it to the one you provided and I get relativly the same error take a look:

    now looks like the toolchain binaries aren't found in your PATH var.
    source the toolchain env file, type:
    source /usr/local/angstrom/arm/environment-setup

    then type:
    arm-angstrom-linux and hit tab a few times and make sure it can find arm-angstrom-linux-gnueabi-g++

    see if that gets you further.
