qt.qpa.wayland: xkbcommon not available on this build, not performing key mapping

rtvideo

Hello, I built a yocto image for the NXP IMX8M Quad using the fsl-image-qt5-validation-imx image and the fsl-wayland distro. I am running a QT application in my imx8 and when trying to enter text into a LineEdit I get "qt.qpa.wayland: xkbcommon not available on this build, not performing key mapping"

I tried doing search's for an answer to this and any solution I saw did not work for me.

Would anyone know how to fix this?

Hi,

What exactly did you try to fix your issue ?
Just based on the error message, it seems that you are missing the libxkbcommon package from your build.

@SGaist I tried doing export QT_QPA_FB_DISABLE_INPUT=1 and QT_QPA_EGLFS_NO_LIBINPUT=1 both did not work. I did not really expect either of them to work but those are two solutions that people have said that worked for them before with similar errors.

SGaist

And did you check that you have libxkbcommon properly deployed on your image ?

rtvideo

@SGaist Yes i installed the libxkbcommon-dev package in my local.conf file

SGaist

Did you check that it's properly deployed on your target ?

rtvideo

Yes it is, I have a xkbcommon directory in my /usr/include folder.

SGaist

That's a run time issue you have not compilation.

Sorry to reopen the ticket. But I think we can add an answer for whoever ends up here in the future.

I have the same issue, also had libxkbcommon into the image under /usr/lib/ and kept having the same error.

The problem was basically on Yocto build I missed configuring the qtbase PACKAGECONFIG variable to enable the xkbcommon option.

To do that, you add a new layer, create a qtbase_%.bbappend file and add:

PACKAGECONFIG:append:<machinename> = " xkbcommon"

NOTE: If you don't add the <machinename> you will have failures because other packages won't have the -native extension.
NOTE2: make sure to do that in a clean build (or clean all qt packages), other ptest will fail complaining that a configuration was changed and it doesn't know why.
