Avalonia Application Crashes on Keyboard Press in Linux Yocto

When using a Avalonia application in Linux Yocto, if you press any key on the keyboard at any moment when the window has focus, the application will instantly crash and give a segmentation fault error.

The error occurs in the method Xutf8LookUpString from the /usr/lib/libX11.so.6 file.

This is only happening in Yocto Linux. The application works fine in Windows.

I was wondering if anyone experienced the same bug or has an idea on how to fix it?

Thanks.

Solution

  • I had a similar issue. Turns out Avalonia is looking for libx11-locale when receiving keyboard events.

    You can try adding the missing package to you app recipe.

     RDEPENDS_${PN} += "x11-locale"

    You can also install libxkbcommon

    This should fixed the segmentation fault.
