Hi devs, I realized that kdelibs version 3.5.12 still has a bug which hit me very recently with 3.5.10 on Mac OS X Lion. The linker was obviously less forgiving concerning undeclared external functions caused due to missing header files, like stdio.h. Please check out http://trac.macports.org/ticket/30314 and see the patch at http://trac.macports.org/browser/trunk/dports/kde/kdelibs3/files/patch-stdi… which made building possible on Lion. Since it's of general platform-independent interest I thought I better post this here as well. Greets, Marko
