Hi, kde4-config can tell me the location of its library and include dir: hammer:~$ /opt/kdelibs/bin/kde4-config --install lib /opt/kdelibs/lib/ hammer:~$ /opt/kdelibs/bin/kde4-config --install include /opt/kdelibs/include/ But kde4-config --types mentions none of both, although kde4-config has the code to document both. The reason is that KGlobal::dirs()->allTypes() doesn't contain these two directories. So, what's the right fix ? Add lib and include to allTypes() or just add the output of these two options to kdelibs/kdecore/kde-config.cpp ? Alex
