QT embedded simulate (up,down,left,right,enter) navigation

BluTiGeS

Hi,
yes i am using the same ones.

The configure command looks as follows:

./configure -release -opensource -confirm-license -arch arm -xplatform linux-arm-gnueabi-g++ -no-icu -no-pch -prefix /usr/local/Trolltech/qt5 -skip qtwebkit-examples -skip qtwebkit

I have adapted the qmake.conf of the linux-arm-gnueabi-g++ to fit my cross compile toolchain.

Do you see any issue?

SGaist

which platform plugins are built ?

BluTiGeS

It is build only for linuxfb platform.

SGaist

How did you install Qt on your board ?

BluTiGeS

I normally just move over the files of the given configure path /usr/local/Trolltech/qt5 to the target board into the same directory.

I found out if I use dbus-uuidgen -ensure before calling the app it starts up without the DBUS warning but the icon warning is still there.

Also I cannot configure qt to work with webkit (see different post).

Regards

SGaist

Did you use your device root filesystem to cross-compile build Qt 5 ? If not, you have probably used a different set of library than the one that's being used on your board

BluTiGeS

How can I use it?

I have just used the above written configure command.

SGaist

Add -sysroot /path/to/your/mounted/device/filesytem to your configure options

BluTiGeS

Thanks,

I have added it but now i get more and more errors.

So i changed back my config to following:
./configure -xplatform linux-arm-gnueabi-g++ -release -opensource -confirm-license -prefix /usr/local/Trolltech/qt5 -make libs -skip qtwebkit-examples -nomake tests -qt-zlib -qt-libpng -qt-libjpeg -qt-freetype -linuxfb -no-opengl -icu

But if I now do a make -j 4 I get an ICU warning, but ICU is needed for webkit, which I also need.

EDIT:
I have updated the icu using the following Cross Tutorial
http://thebugfreeblog.blogspot.de/2013/05/cross-building-icu-for-applications-on.html

now I added the following to the configure :
-icu -I /opt/icuCrossFinal/include -L /opt/icuCrossFinal/lib

Now I got a bit further, I also needed a new linux-atomic version.

I keep you updated on webkit configure,

BluTiGeS

Now I got the qtbase and webkit compiled, but If i want to start the app via

./app -qpa linuxfb:/dev/fb0 it says:

This application failed to start because it could not find or load the Qt platform plugin "xcb".

I checked the dependencies on my Ubuntu 11.04 and I found that Ubuntu is unalbe to locate :
Unable to locate package libxcb-icccm4
Unable to locate package libxcb-icccm4-dev

I then run the configure with -no-xcb and all worked well so far.

But now if I start the application :

./app -qpa linuxfb:fb=/dev/fb0

The screen is not using the full framebuffer (no fullscreen) it seems it is only using 2/3 of it an the rest is cut off.
With qt4 all works as expected.

Any idea why this happens?

Is xcb required for a webkit usage on linuxfb?

SGaist

The plugin might have problem to detect the screen size

BluTiGeS

Any Idea how to fix this?
Also it seems qt5 is a bit slower then qt4, but I thought it should be faster.

SGaist

Did you try to give the screen size to the plugin ?

BluTiGeS

yep, but no influence it changes only to smaller sizes but not to the larger screen size like it should.

SGaist

Looks like a bug, you should check on the bug report system
