[linux-audio-user] Error building qsampler

Hi, I just tried to build qsampler 0.1.2. Unfortunately it failed, regardless if I try to use the Gentoo ebuild or the source from sourceforge. I tried to google for the error messages but I didn't get any results so far. I get the following error: src/qsamplerDevice.cpp: In static member function `static QStringList qsamplerDevice::getDrivers(lscp_client_t*, qsamplerDevice::qsamplerDeviceType)': src/qsamplerDevice.cpp:646: error: `::lscp_list_available_audio_drivers' undeclared (first use here) src/qsamplerDevice.cpp:649: error: `::lscp_list_available_midi_drivers' undeclared (first use here) make[1]: *** [qsamplerDevice.o] Anyone did see something similar? If so, any hint would be great. BTW: I'm using qt-3.3.3. Thanks & best regards, ce
