That doesn't really help with Qt configuration - you can't change any of that at the image level. The way to set this properly is to look at how qt4.inc is structured - note that the -phonon / -no-phonon option for example is set through a variable QT_PHONON. There are several different ways you could set this: 1) Use a bbappend on the qt4-x11-free recipe that sets QT_PHONON = "-no-phonon" 2) Set it from your distro config (or some include file from there) using QT_PHONON_pn-qt4-x11-free = "-no-phonon" 3) Since this variable specifically is being set in the .inc file with ?= and is reasonably well namespaced (i.e. has a name which is unlikely to clash with variables used in other recipes for a different purpose), you could alternatively just set it from your distro config simply as QT_PHONON = "-no-phonon" Cheers, Paul -- Paul Eggleton Intel Open Source Technology Centre -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
