I get this error ../tools/libinput-debug-gui.c:405:9: error: ‘GDK_SEAT_CAPABILITY_ALL_POINTING’ undeclared (first use in this function) GDK_SEAT_CAPABILITY_ALL_POINTING, Don't know what it means. I'm on GalliumOS 2.1, a Chromebook, Samus Sorry I can't really provide anything more than that.
workaround: run meson configure -Ddebug-gui=false <builddir>, then run ninja again, that'll disable the debug gui that requires gtk. I'll push out a fix to check for the right gtk version as soon as the test suite run finishes.
