Cross compiling issues.

Hello everyone!

I'm Dennis from Sweden.

I'm trying to add Swedish keylayout to Qtfrotz, A text adventure engine.
https://www.mobileread.com/forums/sh....php?p=2711142

Said and done. It works on my X11 desktop.
Then I tried the cross compiling...

I found the docker image for cross compiling:
https://github.com/pgaskin/NickelTC
And pulling it:

docker pull ghcr.io/pgaskin/nickeltc:1
Running:
docker run --rm -w /mnt -v "$(pwd):/mnt" -it 671eeb8d3594

and then run qmake,

and then make.

Seems to work. But I get a error when running it on the Kobo:

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

Reinstalling the application may fix this problem.
Aborted

Do you have any hints what this means? I guess this lib is not available on the kobo libra 2. Can I add some flag to exclude to depend on this lib?

Thanks for any hints.

Allt the best,
