[maemo-developers] Undefined Symbol when using QAudioPluginLoader

[From: Andras Toth]

Hello,

I am trying the example "audiooutput" of Qt Mobility API 1.0.2. On Qt emulator 
it runs fine (I can hear the sound), however when I try to run it on the 
device (Nokia N900 with PR1.2 installed), I get the following error message:


QAudioPluginLoader: Failed to load plugin:  
"/usr/lib/qt4/plugins/audio/libn900audio.so" "Cannot load library 
/usr/lib/qt4/plugins/audio/libn900audio.so: 
(/usr/lib/qt4/plugins/audio/libn900audio.so: undefined symbol: 
_ZNK18QAudioEnginePlugin10metaObjectEv)" 

ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM 
Default format not supported - trying to use nearest 
ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM 
...
(the same message repeats many times)
...
ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM 
state =  2 


Am I missing something (e.g. a library), or is it a bug? I've tried Googling 
for some time, but did not find anything useful...

Regards,

András
