libGLESv2.so.2 Error with Qt Application on STM32

[nesnes]

Hi ST Community, @Erwan SZYMANSKI 

I’ve been working on integrating a Qt example from ~/Qt/Examples/Qt-6.7.2/quickcontrols/imagine into my custom Yocto layer for an STM32 board. I created a recipe for this and updated my local.conf accordingly. After building the image and flashing it to my board, I encountered the following error when running the application. I have added my .bb recipe file and local.conf file. (I have qt5 layer installed too)

Hello @nesnes ,
Can you please share the content of your /vendor/lib folder on the board file system please ? If you see nothing, are you sure you well accepted the EULA for the GPU when you sourced your Distribution Package.

Kind regards,
Erwan.

@Erwan SZYMANSKI I encountered this problem when ı was trying to add an example qt application to the board. when ı build my distributions packet ı didn't have any problem, flashing the board works nicely but when I added the

IMAGE_INSTALL_append = " qtbase qtdeclarative qtwayland qtimageformats qtmultimedia"

 line to my local.conf and built st-image-weston again after flashing the board nothing works even the simple ls command. I couldn't understand the problem.

[Erwan SZYMANSKI]

@nesnes ,
2 things to notice :

• The "_append" command is not anymore a syntax supported by Yocto, instead you need to use ":append"
• In your screenshot I do not see any error. If Yocto does nothing, this is because it detects it has nothing more to do and everything you ask to install is already on your image.

Kind regards,
Erwan.

@Erwan SZYMANSKI 

I write in the right syntax when writing local conf like in the last picture.

When I build the distribution package, everything works fine, and the image flashes to the board without any issues. However, after I add the line 

IMAGE_INSTALL += "qtbase qtdeclarative qtwayland qtimageformats qtmultimedia"

to the local.conf file and rebuild the st-image-weston, the number of files in the build drops from around 8000 to 5000. Although the build process doesn't throw any errors, when I flash the board with this image, it becomes stuck on the boot screen, and no commands, not even ls, work. Why could this be happening?

Instead of adding them in IMAGE_INSTALL += should ı do something else to add them to my image ?

The reason why I am trying to this is that I just want to learn how add my example qt application to my board (with adding to my image with my own layer without licensing ) .

@nesnes ,
Just by looking at your issue like that, I do not have a lot of idea.

What is sure is that the "_append" will do absolutely nothing.
Maybe try to add a space after your qtmultimedia " in your IMAGE_INSTALL line. Yocto will just concatenate the variable and so maybe something is going wrong, but I am not sure about that.

If it does not correct anything, I advice you to restart from scratch, with the default Distribution Package we provide that works, then step by step add your part inside and see what provoke the bad situation.

Kind regards,
Erwan.

@Erwan SZYMANSKI I did restart from scratch, with the default Distribution Package and it works fine , but it doesnt work when I add

IMAGE_INSTALL += "qbase"

  when I add this line Tasks Summary: Attempted 7925 tasks dropping to 5555 and when I try to flash , I do it without error but yocto  doesnt work on the board.But when I remove the line it works nicely again.

[Erwan SZYMANSKI]

@nesnes ,
Above I told you about the space and the concatenation in this variable, I would like to see space before and after qtbase : IMAGE_INSTALL += " qbase "

To be sure, use the following syntax :

IMAGE_INSTALL:append = " \
        qtbase \
        xxxx \
        xxxxx \
        xxxxxx \
"

Kind regards,
Erwan.

[nesnes]

@Erwan SZYMANSKII did try it with those syntax nothing changed.

[Erwan SZYMANSKI]

@nesnes ,
Like this, I do not see what happens. If Yocto consider he has less tasks to do, in a way or another, something remove some packages to deploy in the final image, that can explain why you see some things missing when you boot up the board.

But without your complete setup, I will have some trouble to help more.

Can you explain from the very beginning the step you follow ? 

• Ecosystem OpenSTLinux used
• Add X-LINUX-QT layer or not ? 
• You DISTRO and MACHINE, as well as the image you build (I saw st-image-qt )
• Your personal things added into the config (local.conf modification, personal layer etc...)

Kind regards,
Erwan.
