Setup QT Creator with Yocto Build

[Joerg-SH]

bitbaked meta-toolchain-qt

Install it  with

~/yocto/build/tmp/deploy/sdk$ poky-eglibc-x86_64-arm-toolchain-qt-1.4.1.sh

Download Qtcreator from here http://qt-project.org/downloads

and Install it to Your home directory

edit the bin/qtcreator.sh

source /opt/poky/1.4.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi
#! /bin/sh

makeAbsolute() {
    case $1 in
        /*)
            # already absolute, return it
            echo "$1"
            ;;
        *)
            # relative, prepend $2 made absolute
            echo `makeAbsolute "$2" "$PWD"`/"$1" | sed 's,/\.$,,'
            ;;
    esac
}

....

To do it before "#! /bin/sh" is IMPORTANT!!!!

In QtCreator i set

Compiler as

               /opt/poky/1.4.1/sysroots/x86_64-pokysdk-linux/usr/bin/armv7a-vfp-neon-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++

Qt version as

                     /opt/poky/1.4.1/sysroots/x86_64-pokysdk-linux/usr/bin/qmake

sysroot as

                    /opt/poky/1.4.1/sysroots/armv7a-vfp-neon-poky-linux-gnueabi

Put them in a Kit

For connection to Your Board click on  Device  --->    Manage

Dear Joerg-SH:

I using qmake to get the Makefile like this.

../../sysroots/i686-pokysdk-linux/usr/bin/qt5/qmake -spec ../../sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/lib/qt5/mkspecs/devices/linux-imx6-g++/ -o Makefile test.pro

It is no problem when i qmake.

But when i make my Makefile it will show the error like below:

arm-poky-linux-gnueabi-g++ -c -pipe -march=armv7-a -mfpu=neon -DLINUX=1 -DEGL_API_FB=1 -mfloat-abi=softfp -O2 -Wall -W -D_REENTRANT -fPIC -DQT_NO_DEBUG -DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -I. -I../../sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/qt5 -I../../sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/qt5/QtWidgets -I../../sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/qt5/QtGui -I../../sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/include/qt5/QtCore -I. -I. -I../../sysroots/cortexa9hf-vfp-neon-poky-linux-gnueabi/usr/lib/qt5/mkspecs/devices/linux-imx6-g++ -o main.o main.cpp

I'm using qt5.5 to develop my application and Ubuntu 14.04 for my OS.

I don't know why this will happened.

Please Help!

Dear All:

bitbake meta-toolchain-qt5

QT SDK build sucessful

[威宁]

Hello Joerg-SH

     I follow your step to setup QT.

$cd /home/wangq/work/yocto/fsl-release-bsp/sources/poky

$source oe-init-build-env

$bitbake meta-toolchain-qt

But there were some errors.

And I want to know this file（poky-eglibc-x86_64-arm-toolchain-qt-1.4.1.sh） came from where? I am new to all of this and any help would be greatly appreciated. Thanks

Hello,

After "bitbake meta-toolchain-qt", I ran the script "poky-eglibc-x86_64-meta-toolchain-qt-cortexa9hf-vfp-neon-toolchain-qt-1.5.3.sh ", can you check if this script is in your /build/tmp/deploy/sdk/ directory?

[强王]

Dear  Dizon:

     if i want get poky-eglibc-x86_64-meta-toolchain-qt-cortexa9hf-vfp-neon-toolchain-qt-1.5.3.sh

     the current dir is ~/work/yocto/fsl-release-bsp

     the step :

     1：source setup-environment

     2：MACHINE=imx6qsabresd source fsl-setup-release.sh -b build -e fb

     3：bitbake meta-toolchain-qt

      is it right ?

[alvind]

Hello Qiang Wangq,

I actually used a somewhat different method, I just do ". setup-environment build-x11" and then go straight through "bitbake meta-toolchain-qt". Maybe you can try your method and update us with your results.

Thanks

Hi

There is something error  in the execution bitbake meta-toolchain-qt command ,and I can not find this file（poky-eglibc-x86_64-arm-toolchain-qt-1.4.1.sh).

[alvind]

Maybe you can post the contents of /home/wangq/work/yocto/fsl-release-bsp/sources/poky/build/tmp/work/x86_64-pokysdk-linux/gcc-crosssdk/4.8.2-r0/temp/log.do_compile.8418, so we can see the error.

Thanks

Hello Joerg-SH and thank you for this guide. I am using Qt 3.3 have followed your steps to setup Qt creator, and I have a few questions:

1) In specifying the kit, in the compiler tab there is an option for specifying the compiler path and make path. For the compiler path, I used "/opt/poky/1.5.3/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi/arm-poky-linux-gnueabi-g++" but I do not know what to put into the make path, do I just put the normal directory for the make utility?

2) I am using the latest Qt and Qt Creator, but after "bitbake meta-toolchain-qt", I think the version for Qt located within the sysroots folder is 4.8.5. Would this be OK?

I am new to all of this and any help would be greatly appreciated. Thanks

[DipenPatel1z]

Hi Joerg-SH,

Thanks for detailed explanation.

However I noticed that if SDK is installed at path other than default installation path then specifying Qt version in qtcreator doesn't work. I get "Invalid Qt Version" error.

I run qmake -query command and found that all variables point to default SDK installation path and not at where SDK is installed.

Do you have any idea how to solve this?

Regards,

Dipen Patel

Hi guys,

does the meta-toolchain-qt has support for phonon?

[jayrao]

Hi Joreg / Everybody,

I follow the same exact step as mentioned above (with same version of QT creator) ,

but I endup getting ABI detection failed in QT version tab ( i selected qmake2) and it throws exception

I tried clean install many times, but each time its the same.

Any input  on this regard will be highly appreciated.

Thanks

[Joerg-SH]

Hello Jay,

thats "normal" should work properly with that!

If not than should be the mistake on an other place.

regards

Joerg

[jayrao]

Thank you very much Joreg, let me try and see if everything goes fine.

Thanks.

[jayrao]

Hi Joreg,

Now I stumble on this when I try to build  (QT creator 2.8)

The below thread indicated that the follwing env variables has to be set

http://qt-project.org/forums/viewthread/29456

Joreg, do you happen to know if its necessary to add variables in the project build option ?

Thank you .

[Joerg-SH]

There is no need to do that

only

edit the bin/qtcreator.sh

source /opt/poky/1.4.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi
#! /bin/sh

and start i with it

[jayrao]

Got it, Thank you Joreg :smileyhappy:
