Hi Saul, Should we fix the conversion warning in this situation? Or just keep option '-fpermissive' as where it is. If choose to fix the conversion warning, there is already a patch in oe-core to fix this: http://qt.gitorious.org/qt-mobility/qt-mobility/commit/f102053b28009b3094b0e5777177208afa6097c5 If not, I will close this bug.
