      i have install qmake, cross compiler, qt open source, buildroot
      How to use qmake to link buildroot, cross compiler and qtcreator together?

      i tried creating new kit in Qtcreator. It has a big red exclaimation.
      I left Device, Sysroot and Qt mkspec empty because i do not know what to fill in.

        Hi,

        Did you first cross-compile Qt 5 ?

          i did. below is my steps. Pls advice
          How does buildroot comes into picture??

          Below is the information on how I setup QT environment for building imx6 application.

          1. My environment

          lsb_release –a

          • Host: Ubuntu 12.04.5 LTS
          • Release: 12.04
          • Codename: precise
          • QT version

          .qmake -version

          • Qmake version 2.01a
          • Using Qt version 4.8.1 in /usr/lib/i386-linux-gnu

          1. Cross-compiler1 path(arm-linux-gnueabihf g++) for Qtcreator
            /opt/gcc-linaro-arm-linux-gnueabihf-4.7.2013-20130313_linux/bin/arm-linux-gnueabihf g++
            Cross-compiler2 path (arm-none-gnueabi-gcc-4.3.3 g++) for Qtcreator
            /opt/codesourcery/arm-2009q1/bin/arm-none-gnueabi-gcc-4.3.3

          2. Configuring qmake.conf to work with cross compiler

          qmake configuration for building with arm-none-linux-gnueabi-g++

          MAKEFILE_GENERATOR = UNIX
          CONFIG += incremental gdb_dwarf_index
          QMAKE_INCREMENTAL_STYLE = sublib

          #INCPATH +=
          /usr/arm-linux-gnueabi/include

          INCPATH
          #/opt/codesourcery/arm-none-linux-gnueabi/include
          /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/include

          include(../../common/g++.conf)
          include(../../common/gcc-base-unix.conf)
          include(../../common/linux.conf)
          include(../../common/qws.conf)

          #Compiler Flags to take advantage of the ARM architecture
          QMAKE_CFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp
          QMAKE_CXXFLAGS_RELEASE = -O3 -march=armv7-a -mtune=cortex-a8 -mfpu=neon -mfloat-abi=softfp

          modifications to g++.conf

          QMAKE_CC = /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/arm-none-linux-gnueabi-gcc

          QMAKE_LINK = /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/arm-none-linux-gnueabi-g++
          QMAKE_LINK_SHLIB = /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/arm-none-linux-gnueabi-g++

          modifications to linux.conf

          QMAKE_AR = /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/arm-none-linux-gnueabi-ar cqs
          QMAKE_OBJCOPY = /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/arm-none-linux-gnueabi-objcopy
          QMAKE_STRIP = /opt/gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux/arm-linux-gnueabihf/arm-none-linux-gnueabi-strip

          load(qt_config)

          #-----------------------------------------------------------------------------

          #/home/common/Desktop/qt-opensource/qt-everywhere-opensource-src-4.7.3/mkspecs

          export DISPLAY=:0
          #export QT_QWS_FONTDIR=/opt/

          1. Build and install
            $ make –j 4
            $ sudo make install

          2. Configure Compiler
            Build & Run ->Compilers and click Add-> GCC
            Select compiler path:

          3. Configure Kit
            Kits and click add
            Call new kit sabrelite
            • Name: ARM g++
            • Device type: Generic Linux Device

            • Qt version: Qt 5.3.0 GCC 32 bit
            • Qt mkspec: leave empty

          4. Build Qt Application
            Create new project (console)
            Edit project (.pro) file
            Target.path =/home/root
            INSTALL =target

            Which qmake are you using ? The one from your system Qt or the one you cross-built ?

              you did not answer first question. Can you write more for me to understand your thought, thought process, to absorb some of your know-how

                  There's something absolutely not clear about your setup, there's Qt 5.3.0 Qt 4.8.1 and 4.7.3 mentioned in there.

                  Which version of Qt do you want to use on your target, which one did you install on your system ? How did you install it ?

                    Hi

                    I will announced my steps in another day, they are proven working until i put the image into target.

                    I did succeed putting the image into target. But in the target, when i touch my dialog boxes. it is removed/deleted reviewing the background. What did i done wrongly. do i need Tslib to be installed to enable touchscreen.

                      I can't answer that, I don't know your software or how it is supposed to run

                          Below is my build process
                          Building and setting up QT environment for IMX 6

                          1. Set cross compile path

                          export PATH=$PATH:/opt/freescale/usr/local/gcc-4.6.2-glibc-2.13-linaro-multilib-2011.12/fsl-linaro-toolchain/bin/

                          arm-none-linux-gnueabi-gcc -v

                          You will see “gcc version 4.6.2 20110630 (prerelease) (Freescale MAD -- Linaro 2011.07 -- Built at 2011/08/10 09:20)” at last line
                          2. In your qt-everywhere-opensource-src-4.7.4
                          Modify mkspecs/qws/linux-arm-g++/qmake.conf
                          QMAKE_CC = arm-none-linux-gnueabi-gcc
                          QMAKE_CXX = arm-none-linux-gnueabi-g++
                          QMAKE_LINK = arm-none-linux-gnueabi-g++
                          QMAKE_LINK_SHLIB = arm-none-linux-gnueabi-g++
                          QMAKE_AR = arm-none-linux-gnueabi-ar cqs
                          QMAKE_OBJCOPY = arm-none-linux-gnueabi-objcopy
                          QMAKE_STRIP = arm-none-linux-gnueabi-strip
                          3. In your qt-everywhere-opensource-src-4.7.4

                          ./configure -embedded arm -qt-zlib -qt-libpng -qt-gif -qt-libtiff -qt-libmng -qt-libjpeg -qt-freetype -no-openssl -static -prefix /media/jt_disk2/QT

                          “/media/jt_disk2/QT” is my QT install path
                          4. make
                          5. make install
                          Building your code to target board

                          1. Set environment variable

                          export QTDIR=/media/jt_disk2/QT/

                          export PATH=$QTDIR/bin:$PATH

                          export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

                          qmake -version

                          You will see QT version and QT in your install path
                          2. In your code dir

                          qmake -project

                          qmake

                          make

                          1. Copy binary file to target board
                          2. Copy ${QT install}/lib/fonts to target board's /usr/lib/
                          3. export QT_QWS_FONTDIR=/usr/lib/fonts
                          4. Run QT binary file

                          ./Your_QT -qws

                            Before anything else, if you're not tied to that particularly old version of Qt you should first update to 4.8.6
