Setup QT Creator with Yocto Build

Joerg-SH — Thu, 11 Jul 2013 20:15:32 GMT

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

Build a new project

and add some to the .pro file

Building the image for Your Board:

add

TOOLCHAIN_HOST_TASK_append = " nativesdk-python-subprocess"

EXTRA_IMAGE_FEATURES = "debug-tweaks ssh-server-openssh"

to Your localconfig

bitbake core-image-sato-sdk

set a password to root via

ssh root@[boardip]

passwd

test connection via

Good Video to get more Information about Programming are this

Beaglebone: LCD Touchscreen GUI Applications for Embedded Linux - YouTube

Beaglebone: Qt Creator for C++ ARM Embedded Linux Development - YouTube

Beaglebone: Example Qt Embedded Linux Application - YouTube

It is for Beagelbone but for programming Qt it is a good start.

Hello Joerg

We have followed this steps and have QT 4.8 applications running on both systems, Desktop and imx6 target. But we have problems with debugging:

on desktop: https://community.freescale.com/message/348541#348541 , and

on target: https://community.freescale.com/message/348540#348540

Desktop)

This problem seems to be related to python. But I am no used to it. It seems as if site.py was trying to import the get_config_var function from sysconfig.py. Then the process is stopped at the beggining of sysconfig.py. However the files are untouched from their compilation date. Any clue?

Target)

The message on the Debugger Log window seems to say that bb is a GDB command but I am no able to find it in any GDB page. I have a windows station with a test QT 5.0 instalation. There the bb command works. Both QTs, 4,8 and 5,.0, are using GDBs 7.5.1. So, is really bb a GDB command? Any hint about why bb is not defined?

Thanks and best regards

Hello Diego,

sorry I didn`t try that till now.

Have a look at Dereks Video.

Thanks Joerg

Desktop Mode Debugger problem news)

We start QT after deleting the line:

source /opt/poky/1.4.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi

from qtcreator.sh. Without it, QT Debugger shows the variables and its values.

Something is not well defined inside that file and it makes fail the GDB local mode start.

We saw he video but I fear we have not enough experience to extract the conclusion we look for. We review it more slowly from time to time.

Best regards

Hello

Found ... we think.

Line: bitbake meta-toolchain-qt

compiles a Python 2.7.3 without some default modules: for example subprocess

Line: source /opt/poky/1.4.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi

changes PYTHONHOME and redirects it to /opt/poky.../python

When QTCreator execute the python dumpers to show the variables, it needs the lost modules. So we go to the next questions:

It is necessary use the /op7/poky/... /python or we can use Ubuntu python?

How can I say to meta-toolchain-qt to generate a complete python version?

Thanks and best regards

Hi Joerg

Solved adding the line:

TOOLCHAIN_HOST_TASK_append = " nativesdk-python-subprocess"

in build/conf/local.conf from Yocto.

That adds the module subprocess to python used by QTcreator

Now I can view variables at breakpoint running an application on target.

Thanks

Hello Jay,

thats "normal" should work properly with that!

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

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 — Tue, 12 Nov 2013 19:05:45 GMT

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

cleonbrown — Sun, 09 Feb 2014 20:50:16 GMT

i added the line " source /opt/poky/1.5.1/environment-setup-armv7a-vfp-neon-poky-linux-gnueabi" to qtcreator.sh before "#! /bin/sh" line and I am still having the same problem. do you know what else could cause this. I dont think it is recognizing the line added to the qtcreator.sh file because when i launch it from terminal with the line it stated "source not found". please help.

i'm using poky version 1.5.1

Re: Setup QT Creator with Yocto Build

cleonbrown — Mon, 10 Feb 2014 03:06:03 GMT

SOLVED: you must launch qtcreator like this: ./qtcreator.sh ONLY.

Hi guys,

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

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

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

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?
