Hi Vishvapathi,

we had successfully builded QT on IMX6 board using LTIB. And we are able to run QT applications. You can look into the following steps to build QT using LTIB.

Porting of Qt on i.MX6 board

Step1:

For porting qt on i.MX6 board you need ltib setup in your linux machine.
Download qt-open source 4.6.0.tar.gz from the below link.

http://pkgs.fedoraproject.org/repo/pkgs/qt/qt-everywhere-opensource-src-4.6.0.tar.gz/2a7b5126f2450d8525af355fc4c12ad6/

and put the tar file in /opt/freescale/pkgs location.
Edit the spec file located in /ltib/dist/lfs-5.1/qt/qt-embedded.spec, according to the package version downloaded.

Step2:

cd to your ltib path
Type the following command to open ltib config

$ ./ltib –m config

We get the following screen. Select the Packages option

Then select the qt-embedded option

Save the changes. Run the ltib by using the following command.

$ ./ltib

This starts building qt-everywhere-opensource package.

Step3:

Flash the root file system which build with qt embedded on to the sdcard

ON THE IMX6 BOARD

-> Export the fonts folder on i.MX6 board

Ex: export QT_QWS_FONTDIR=/usr/local/Trolltech/lib/fonts

Step4:

Run <your-qt-executable> with –qws option (qt windowing system).
Ex: ./<your-qt-executable> -qws

Thanks & Regards,

Raybiztech.

Hi,

Thanks for your response. I downloaded the setup and moved it to /freescale/pkgs. But wen i compile the ltib is looking for setup in web, instead of pkgs folder.

%define pfx /opt/freescale/rootfs/%{_target_cpu}

Summary : Qt

Name : qt-everywhere-opensource-src

Version : 4.6.0

Release : 0

License : GNU GPL

Vendor : Freescale

Packager : Rogerio Pimentel

Group : System Environment/Libraries

Source : %{name}-%{version}.tar.gz

BuildRoot : %{_tmppath}/%{name}

Prefix : %{pfx}

URL : http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.0.tar.gz

Do i have to make any modification in qtembedded.spec file to look for source in pkgs folder????

Re: Reg: QT application error

Raybiztech — Mon, 14 Oct 2013 08:43:05 GMT

Hi Vishvapathi,

Please make sure that, the " Name " and " Version " fields in the spec file matches exactly with the package copied into your /opt/freescale/pkgs/ and try building the package again using " ./ltib ". If still its looking for setup in web. you can build the package by following the below steps :

-> ./ltib -m prep -p qt-everywhere-opensource.spec (mention the same name as in the spec file)

-> ./ltib -m scbuild -p <packagename>

-> ./ltib -m scinstall -p <packagename>

-> ./ltib -m scdeploy -p <packagename>

Thanks & Regards,

Raybiztech.

Re: Reg: QT application error

Raybiztech — Mon, 14 Oct 2013 10:20:36 GMT

Hi Vishvapathi,

LTIB will search for the package in the LPP if it is found, it will proceed with prep or else it will fetch the package from GPP. And the GPP url mentioned in the spec file is not valid. so it can't able to fetch the package. And extension of the package its searching is " .tar.gz " so make sure your package in LPP is named exactly with same extension as " qt-everywhere-opensource-src-4.6.0.tar.gz ". Download the package from the below mentioned site and copy it into /opt/freescale/pkgs.

Index of /repo/pkgs/qt/qt-everywhere-opensource-src-4.6.0.tar.gz/2a7b5126f2450d8525af355fc4c12ad6

Raybiztech — Mon, 14 Oct 2013 10:31:21 GMT

Hi,

I haven't tried with this 4.7.3 version because it may lead to more errors. Because what ever dependency packages builded before, used by QT must be updated for this 4.7.3 version. Better try with 4.6.0 if you are using LTIB. or else build 4.7.3 explicitly.

Thanks & regards,

Raybiztech.

hello,

I have followed this post and was successful building qt-everywhere-opensource-src-4.6.0 with ltib and L3.0.35_4.1.0_130816 after some attempts. However it appears I only have the examples and demos built.

For example:

root@gumby /usr/local/Trolltech/demos/embedded/fluidlauncher$ ./fluidlauncher

QWSSocket::connectToLocalFile could not connect:: Connection refused

No Qt for Embedded Linux server appears to be running.

If you want to run this program as a server,

add the "-qws" command-line option.

root@gumby /usr/local/Trolltech/demos/embedded/fluidlauncher$

<tech/demos/embedded/fluidlauncher$ ./fluidlauncher -qws

QFontDatabase: Cannot find font directory /home/~/imx6_project3/ltib/rpm/BUILD/../../rootfs/usr/local?

Aborted

root@gumby /usr/local/Trolltech$ ls -l

drwxr-xr-x 27 root root 4096 Feb 24 2014 demos

drwxr-xr-x 44 root root 4096 Feb 24 2014 examples

I am building a minimum profile.

What pkgs are need to get a full qt implementation?

thanks

Re: Reg: QT application error

Raybiztech — Tue, 25 Feb 2014 05:55:41 GMT

Hi,

May be this is the problem with font directory ,have you tried,

export QT_QWS_FONTDIR=/usr/local/Trolltech/lib/fonts

Please make sure that fonts directory is available in /usr/local/Trolltech/lib/, otherwise copy it from /ltib/ltib/rpm/BUILD/qt-everywhere-opensource-src-4.6.0 /lib/fonts to /usr/local/Trolltech/lib/.

Then run your application as ./fluidlauncher -qws

Thanks,

Raybiztech.

HI:

Above,you said:copy it from ltib/rpm/BUILD/qt-everywhere-opensource-src-4.6.0 /lib/fonts to /usr/local/Trolltech/lib/.

I also cann't find it.

Raybiztech,Please give me some advice
