Run QT Software on Linaro

It appears that you can just point QT Creator to a different compiler.  Ref link:

http://doc.qt.digia.com/4.7-snapshot/qt-embedded-crosscompiling.html

You can set QT to compile all of the libraries into your binary if you want, or you can copy all of the libraries you are using to your roomfs (I would recommend the former).

I would not recommend running QT Creator on the zedboard itself, as you are not going to get any where near the performance of your PC.

Thanks for your advices, Tim.
If I want to compile the QT app, which cross-compiler should I use, The arm-xilinx-linux-gnueabi or Linaro toolchain? I was trying to compile an app using Xilinx toolchain and it failed to run on Linaro. So I guess the latter can be used to do the job. And is that possible to install the Qt-lib on Linaro derectly so that I can both complie and run Qt apps on my zed?

You certainly could get the qt compiler and associated libraries moved over to your Zedboard if you wanted to - I personally prefer to cross-compile as it usually is much faster (but if you are talking about small applications then it really shouldn't make much of a difference).

As for which cross compiler to use, I have had the most luck with the arm-xilinx-linux-gnueabi toolchain - but I haven't compiled a qt program yet.

Give them both a shot and let us know which one works!

Hi , I am also trying to do the same stuffs on My xilinx zc702 board.

But I got stuked and it was not getting fired up.

Below are the steps I have tried to build and compile the same.

1) qt-everywhere-opensource-src-4.7.3.tar.gz(Extract It on host)
2) qmake.conf:
        Replace: arm-none-linux-gnueabi-gcc by arm-linux-gnueabihf-gcc

3) Set the path:
    export CROSS_COMPILE=arm-linux-gnueabihf-
    export PATH=/usr/bin:$PATH
    export ZYNQ_QT_BUILD=/home/user/qt-everywhere-opensource-src-4.7.3
    export ZYNQ_QT_INSTALL=/usr/local/Trolltech
    export PATH=$ZYNQ_QT_INSTALL/bin:$PATH

4) ./configure -embedded armv7l -xplatform qws/linux-arm-gnueabi-g++ -little-endian -opensource -host-little-endian -confirm-license -prefix $ZYNQ_QT_INSTALL -qt-zlib -qt-libtiff -qt-libpng -qt-libmng -qt-libjpeg -no-openssl -no-nis -no-cups -iconv -no-pch -no-dbus -qt-freetype -no-opengl -qt-gfx-linuxfb -qt-gfx-vnc -qt-gfx-qvfb
(This we tried with arm as well)

5)  make
    make -install
    copied all the libraries(from /usr/local/Trolltech) to the target board at (/usr/local/Trolltech).

6) ./appname -qws -display QVFb:0
     error:  driver cannot connect
     Aborted
(Cause:This I think we donu2019t have to use as we are running linux so have to use LinuxFb)

    ./appname  -qws LinuxFb:mmwidth=1024:mmheight=768
    this does not give any error but, it's not launching the GUI but printing the log messages in terminal.

can you tell What we are missing here.

Check out buildroot:
http://buildroot.uclibc.org/u200E
It creates a root filesystem, cross compiling all the libraries you select in a menu-driven (not unlike the Linux kernel configuration) build system.

Hi ,
As we are using the Linaro Ubuntu Desktop so they are providing the pre built Linaro file system alongwith the Xilinx board but ucilibc is different file system so whether it will work fine on Zed Board with GUI desktop.

Hello! I want to run Qt applications on my zedboard. But I don't know how to install the Qt tool chains. I have downloaded "qt-embedded-linux-opensource-4.5.3.tar.gz", and installed arm-linux-gnueabi-gcc and arm-linux-gnueabi-g++. Then I used command "./configure -embeded arm" to configure. At this time, errors occurred, such as: arm-linux-g++ can not found. So, I want to know how to install Qt cross compiling environment. I just want to create and compile my app on PC host, then copy the result to zedboard with linux OS. Can anyone help me ?

Hi, i have the same issue, is there any sollution yet ?
