How to Cross compiling Qt/X11 for beagleboard?


  • Hi all,
    I have got a beagleboard, I use angstrom for linux platform, I want to port QT 4.6.2 x11 for this board, and I followed http://labs.qt.nokia.com/2009/09/10/cross-compiling-qtx11/
    But I encountered the configuration problems, I can't configure the makefile.

    my environment:
    Ubuntu 10.04
    Scratchbox2 2.0-lta101
    I downloaded the toolchain form http://www.angstrom-distribution.org/toolchains/angstrom-2010.4-test-20100422-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.2.tar.bz2
    the qt source file form http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.2.tar.gz

    I untar the toolchain to /usr/local/angstrom, the sourced the toolchain environment file.

    Then, followed the http://labs.qt.nokia.com/2009/09/10/cross-compiling-qtx11/ steps.

    use "bitbake beagleboard_demo_image" built the angstrom image, then untar it to a folder, and sb2 init there.

    When I try to configure the makefile, I encountered these error.

    my configure command is sb2 ./configure -arch arm -xplatform qws/linux-arm-g++ -force-pkg-config -v

    Please help me :)

  • Hi, I'm trying to do the same.
    But I'm using Angstrom image and SDK from http://narcissus.angstrom-distribution.org/ .

    Have you solved your problem?

  • yes, i set the wrong toolchain environment, should not use angstrom environment

  • Hi:
    I'm using Angstrom image and SDK from http://narcissus.angstrom-distribution.org/ . But I don't know how to use the SDK, could you give me some advice?

    Thanks a lot.

  • I'm also using Angstrom and SDK from Narcissus to get QT running on a BeagleBoard-xM. I followed Luca's instructions at https://qt-project.org/wiki/Qt_on_the_BeagleBoard, although every time I use a complicated choice of options, the Narcissus page never completes building the package. So instead I started with a basic console-only version fo Angstrom and used 'opkg install <pkg>' to install most of the packages that Narcissus said it was putting together. From Narcissus I did get the SDK package, though, and extracted that to /usr/local/angstrom/arm. Now, I've got an X11 environment with network connectivity and displaying to an LCD monitor. However, I haven't been able to build a Hello World Qt project because my QMAKESPEC isn't setup correctly, which is where I need help.

    Normally, it looks like all the .conf files are in /usr/share/qt4/mkspecs/. I'm using G++, so my .../mkspecs/linux-g++/qmake.conf points to .../mkspecs/common/linux.conf and .../mkspecs/common/g++.conf.
    However, in the Angstrom-2012.03-narcissus-beagleboard-i686-random-2c3363a0-image-sdk.tar.gz package I got from Narcissus, /usr/local/angstrom/arm/ contains on an 'environment-setup' file and no mkspecs directory. In 'environment-setup' QMAKESPEC isn't defined. So when I source 'environment-setup' and then run qmake2, I get the error "QMAKESPEC has not been set, so configuration cannot be decuced."

    I also tried copying my Ubuntu copy of /usr/share/qt4/mkspecs/ to the Angstrom SD card at /usr/local/angstrom/arm/mkspecs/ and then added a QMAKESPEC definition in /usr/local/angstrom/arm/environment-setup to point to my new /usr/share/qt4/mkspecs/linux-g++. qmake2 seemed to be successful, but when I make the project, I get the error "g++ -c -pipe -O2 -Wall -W -D_REENTRANT -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I/usr/share/qt4/mkspecs/linux-g++ -I. -I/OE/angstrom-2008/build/tmp-angstrom_2008_l/sysroots/x86_64-linux/qt4/include/QtCore -I/OE/angstrom-2008/buld/tmp-angstrom_2008/build/tmp-angstrom_2008_l/sysroots/x86_64-linux/qt4/include -I. -o main.o main.cpp"

    and after that, the rest of the errors are that it can't find the QApplication and QPushButton headers...

    So my question is ...

    1. Should I have added an "export QMAKESPEC=..." line to /usr/local/angstrom/arm/environment-setup and if so, where should it point to?
    2. Was the Angstrom Qt SDK supposed to include the mkspecs folder?

    Since I'm just learning Qt and don't know these files yet, I guess my next option is to setup an OpenEmbedded build environment and try to build Qt from scratch.

  • Also, Luca's instructions say to install the Qt src wherever you want. Is there another environment variable that's supposed to point to where the source code is?

  • hi i got similar problem
    i tried to compile the QT with following command by following “http://forums.digi.com/support/forum/viewthread_thread,6858#20693”

    ./configure -confirm-license -embedded arm -xplatform qws/linux-arm-g++ -prefix /usr/local/QtEmbedded-4.4.3 -hostprefix /usr/local/DigiEL-5.6/x-tools/arm-cortex_a8-linux-gnueabi -qt-sql-sqlite -depths 15,16 -qt-kbd-usb -qt-mouse-tslib

    and i got this error

    Basic XLib functionality test failed!
 You might need to modify the include and library search paths by editing
QMAKE_INCDIR_X11 and QMAKE_LIBDIR_X11 in /home/qmax/Desktop/QT_Latest/qt-x11-opensource-src-4.5.3/mkspecs/qws/linux-arm-g++.

    I tried the following
    Try 1:

    sudo apt-get build-dep qt4-qmake (installed)

    Ref:http://www.qtforum.org/article/27401/debian-xlib-test-failed-after-configure.html
