Qt5 using the DORA branch

Qt5 using the DORA branch

[Marco]

Hello
This is likely the continuation up of thread "[meta-freescale] Error 
0x300b in Qt5 applications with EGLFS"


I am building qt5 using the DORA branch and meta-qt5.
These are my image settings:

IMAGE_INSTALL_append = "qtbase qtbase-fonts qtbase-plugins 
qtbase-examples cinematicexperience gstreamer nano cairo pango 
fontconfig freetype"
DISTRO_FEATURES_remove = "x11 wayland"


Build Configuration:
BB_VERSION        = "1.20.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "Ubuntu-12.04"
TARGET_SYS        = "arm-poky-linux-gnueabi"
MACHINE           = "imx6dlsabresd"
DISTRO            = "poky"
DISTRO_VERSION    = "1.5"
TUNE_FEATURES     = "armv7a vfp neon callconvention-hard cortexa9"
TARGET_FPU        = "vfp-neon"
meta
meta-yocto
meta-yocto-bsp    = "dora:75bed4086eb83f1d24c31392f3dd54aa5c3679b1"
meta-oe           = "dora:513e7ca20ddd0a5c3b649bf292a67c3e0473d3a8"
meta-fsl-arm      = "dora:5b3b6618426ad06e4fb6a3a77c4a53dfb47f0556"
meta-qt5          = "dora:cefaba69a785c5221463f0eb496b749d5ddf8a5a"


To successfully build qt5 I removed the cmake directory in 
recipes-devtools and apply this patch 
http://patchwork.openembedded.org/patch/60673/ to Qt5 (I know its not 
the best way and Otavio doesn’t like it :P ). I am also putting USE_X11 
= “no” in 
sources/meta-fsl-arm/recipes-graphics/gpu-viv-bin-mx6q/gpu-viv-bin-mx6q.inc 
so framebuffer gpu drivers get included.


I completed the bitbake successfully, then I created my SDcard.
Unfortunately now I have errors launching examples (see below)

root@imx6qsabresd:~# /usr/share/qt5/examples/gui/analogclock/analogclock
QXcbConnection: Could not connect to display

What am I missing?
Any hint is greatly appreciated

Hi!

Everything looks ok except this segfault ;) Can you run it under gdb and
show us where exactly it is crashing?

Cheers,
Filip

This "..._wayland.c" looks suspicious to me. Are you sure you are using
framebuffer variant of graphics libraries? Try 'ls -la /usr/lib/libGAL*'
and 'ls -la /usr/lib/libEGL*'.

I think the line DISTRO_FEATURES_remove = "x11 wayland" 

is needed to remove x11 and wayland 

 

I also would suggest you to start again with a fresh build.

When I did do that it did work for me using this method:

 

Download the meta-qt5 layer in your sources folder:

git clone https://github.com:dora/meta-qt5/meta-qt5.git

 

In the build/conf/bblayer.conf file add:

${BSPDIR}/sources/meta-qt5 \

${BSPDIR}/sources/meta-openembedded/meta-ruby \             (not sure if
this one is needed)

 

In local.conf add: 

IMAGE_INSTALL_append = " kernel-modules fontconfig freetype qtbase
qtbase-plugins qtbase-tools qtbase-fonts cinematicexperience" 

DISTRO_FEATURES_remove = "x11 wayland" 

 

bitbake core-image-minimal

 

I did get an error about the
sources/meta-qt5/recipes-devtools/cmake/cmake_2.8.12.1.bbappend file 

and because dora has cmake 2.8.11.2 i decided to delete
cmake_2.8.12.1.bbappend to make it build.

 

deploy the image on your target

 

Start the Qt5 Demo:

Qt5_CinematicExperience -platform eglfs &

 

For the touch screen support in Qt:

 

Load your touch screen driver and:

 

export QT_QPA_EVDEV_TOUCHSCREEN_PARAMETERS=/dev/input/event2   (adjust
to your situation)

export QT_QPA_EGLFS_HIDECURSOR=1                        (remove the
mouse cursor)

 

With kind regards.

it's needed for webkit IIRC.

Ho Otavio,

I restored the original file
meta-fsl-arm/recipes-graphics/gpu-viv-bin-mx6q/gpu-viv-bin-mx6q.inc

Doing as you said I get an error when I rebuild

To all that have problems using Qt5:

 

I have a colleague who has a lot of experience building and configuring
qt5 with buildroot.

He told me that when rebuilding, Qt does not correctly changes its new
configuration 

and some files of the old output stay behind and are used again as input
and cause troubles.

 

So this is why I did put the advice to start with a clean build.

I know it takes time but only after I did do that everything build
correctly and the Cinematic Experience demo works.

 

To check the result of the qt configure you can take a look at this
file:

your_build_dir/tmp/work/cortexa9hf-vfp-neon-mx6-poky-linux-gnueabi/qtbas
e/5.1.1-r0/build/config.summary

With kind regards, Sake

Hi Sake
I rebuilt all from scratch.
I was able to build with the following settings but I am not able to run 
Qt5 apps on my iMX6 target.

IMAGE_INSTALL_append = " qtbase qtbase-fonts qtbase-plugins 
qtbase-examples qtbase-tools cinematicexperience gstreamer fontconfig 
freetype "
DISTRO_FEATURES_remove = "x11 wayland"

meta-yocto-bsp    = "dora:53d2563ff13fcec74d4250bef5419e36169e55cc"
meta-oe           = "dora:513e7ca20ddd0a5c3b649bf292a67c3e0473d3a8"
meta-fsl-arm      = "dora:87601e5fc93b422347b22fe6d41f38f18f6ee9ec"
meta-qt5          = "dora:cefaba69a785c5221463f0eb496b749d5ddf8a5a"

Which branch are you using (for yocto and meta-qt5)?
Are you applying any patch to meta-qt5?

TIA
