Version: (using KDE KDE 3.5.7) Installed from: Unspecified OS: Linux When compiling konq-plugins (from 3.5.7) with "make -j" (i.e. parallel make), I get the same error message as in this Gentoo bug: http://bugs.gentoo.org/show_bug.cgi?id=112214 I've hunted the reason to be that widget.h is not yet generated before it's needed. Simple fix is to make sure widget.h is generated first, by a simple Makefile.am trick.
Created attachment 21427 [details] Fixes parallel make problem in konq-plugins/sidebar/delicious
Obsoleted by the switch to cmake in kde4. (please reopen if the problem still exists though)
