Preparing build tree...

<outbase> = /home/tjmaciei/obj/qt/qt5-clang/qtbase

Creating qmake...
.........................................................................................Done.


Qt is now configured for building. Just run 'gmake'.
Once everything is built, Qt is installed.
You should not run 'gmake install'.

Prior to reconfiguration, make sure you remove any leftovers from
the previous build.
