Right, for Qt/E if you are displaying any text you'll need to explicitly install the package for this since nothing depends upon it. You can install the qt4-embedded-fonts package which brings in all fonts that are distributed with Qt, or alternatively you can install only the fonts you want (qt4- embedded-fonts-ttf-vera, etc.) > Pretty sure I need the first 3, but not sure about the rest.

Note however if you start changing some of the build-time configuration options for Qt you may be able to disable a few things you don't need. Have a look at Qt's configuration options [1]. You can see exactly which options are being used to build Qt with: bitbake -e | grep "^QT_CONFIG_FLAGS=" If you search for QT_CONFIG_FLAGS under meta/recipes-qt/qt4/ you'll see how this variable gets set. > I guess also at some point we might want to switch to Qt5.
