I tried to compile (host has Xt with dev headers), but Webkit still doesn't compile, maybe due to it being compiled before X (I specified TinyX). checking for XtOpenDisplay in -lXt... no configure: error: X Toolkit Intrinsics library (libXt) not found make: *** [/home/dan/xenon/buildroot/output/build/webkit-r44552/.stamp_configured] Error 1
Do you still encounter this issue ? If so, could you attach your .config ? It's fairly strange to see WebKit asking for Xt. Xt is a very old toolkit that almost nobody uses these days.
