Hi I am building a Linux image with some customized layers. Since I would like to run a Qt-based graphic UI on the Linux operating system, I also added the qt5 layer.
The image building method is mainly based on Toradex’s instruction. However, when I built and installed the image on my Apalis imx6, I got following error message when running my application:
This application failed to start because it could not find or load the Qt platform plugin “eglfs”
Is there any hints?
My configuration file is here: bblayer.conf and local.conf
Thank you!
=================================================
Following are some basic information:
I used LinuxImageV2.8
repo init -u http://git.toradex.com/toradex-bsp-platform.git -b LinuxImageV2.8
and the bitbake command is:
bitbake -k console-tdx-image
The bblayers.conf file:
# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "7"
BBPATH = "${TOPDIR}"
BBFILES ?= ""
BBLAYERS ?= " \

And I have added following lines in the local.conf file since I would like to run Qt applications, printer services and native compilation on my Linux image:
IMAGE_INSTALL_append = " packagegroup-sdk-target"
IMAGE_INSTALL_append = " cups-dev"
IMAGE_INSTALL_append = " cups-filters"

Hi @mzkmzk89
Thanks for writing to the Toradex Community!
Concerning your issue, you need to include some packages in your image as described here .
Best regards,
Hi Jaski,
Thank you for your reply! Actually I did not see file “qtbase_%.bbappend” in my qt folder.
I was searching this folder: “oe-core/layers/meta-qt5/recipes-qt/qt5”
Should I create a new one file?
Thank you!
Hi Zhaokai
Yeah, you need to create the .bbappend file.
Best regards,
Hi Jaski,
Thank you for your help. Nevertheless, after creating a new .bbappend file, I still met following problem. Seems like the problem is related with the gbm library.
ERROR: Feature 'gbm' was enabled, but the pre-condition 'libs.gbm' failed.
In the qtbase_%.bbappend file, I entered:
PACKAGECONFIG_append = " linuxfb eglfs gbm gles2 kms"
PACKAGECONFIG_remove = "gl xcb xcb-xinput"
I got following output from the console:

Hi Jaski,
I met some issues while compiling the OS, and seems like the problem is related with the GBM library. I have attached description as a reply of the original message (see below). Do you have any hints?
Thank you!

Hi Zhaokai
@mzkmzk89
It looks like we sent you down the wrong path.link explains how to build with EGLFS if you use a mainline kernel and the etnaviv graphics stack. However you do not seem to want to build against mainline/etnaviv.
Using the downstream kernel / proprietary Vivante graphics stack doesn’t pull in gbm resulting in your build-errors.
So I would first revert the changes you did because of said link. Sorry about that.
For me, the 2.8 BSP configured with the hints from here results in an Image where I can start the Qt5_CinematicExperience with:
Qt5_CinematicExperience -platform eglfs
One thing to note is that you must delete all your build output and sstate when changing DISTRO_FEATURES. If you ever built an image with X11 in your setup you should delete first:
rm -rf deploy/ build/tmp-glibc/ build/sstate-cache/
Unfortunately after this bitbake will have to rebuild everything.
I hope that this rebuild fixes your issue This application failed to start because it could not find or load the Qt platform plugin “eglfs” .
If that error is still shown could you add the following build logs:
tmp/log/cooker/apalis-imx6/ console-latest.log
tmp-glibc/work/armv7at2hf-neon-mx6qdl-angstrom-linux-gnueabi/qtbase/5.9.7+gitAUTOINC+81b29a44d2-r0/temp/ log.do_configure log.do_compile
and the qtbase.txt file created by:
bitbake qtbase -e > qtbase.txt
