I can't build qtmobility on Ubuntu 11.10. I tried building with qt4.7 and qt4.8, but both produced the same error:

/home/doriad/src/qtmobility/src/serviceframework/ipc/qmetaobjectbuilder.cpp: In member function 'void QtMobility::QMetaObjectBuilder::addMetaObject(const QMetaObject*, QtMobility::QMetaObjectBuilder::AddMembers)':
/home/doriad/src/qtmobility/src/serviceframework/ipc/qmetaobjectbuilder.cpp:803:65: error: invalid conversion from 'QMetaObjectExtraData::StaticMetacallFunction
