Error building PPSSPP with QT frontend

[maz_1]

system:opensuse 12.3 x86-64
I build PPSSPPQt.pro with qt creater 2.6.2,and it interrupts with such errors:
/home/ling/ppsspp/native/base/QtMain.h:9: error:QAudioOutput: No such file or directory
Is there a missing dependency?There is already QAudioOutput.h under /usr/include/QtMultimedia/.
