trying portaudio example, but getting "ld: symbol(s) not found for architecture x86_64"
audio, c, linker, macos, portaudio
Solution
You need to include the Apple frameworks:
- CoreServices.framework
- CoreFoundation.framework
- AudioUnit.framework
- AudioToolbox.framework
- CoreAudio.framework
and as you already did libportaudio.a
Problem
I'm trying to use portaudio on Mac OS 10.10, but I'm getting an error when attempting to compile an example program. Here's what I've done: -./configure && make. No problems. -copied the example file "pa_devs.c", libportaudio.a, and portaudio.h into a separate directory called Test1 -tried to compile it ``` gcc -o Test1 pa_devs.c libportaudio.a -lm ``` -got this error: ``` Undefined symbols for architecture x86_64: "_AudioConvertHostTimeToNanos", referenced from: _GetStreamTime in libportaudio.a(pa_mac_core.o) _AudioIOProc in libportaudio.a(pa_mac_core.o) "_AudioConverterDispose", referenced from: _CloseStream in libportaudio.a(pa_mac_core.o) "_AudioConverterFillBuffer", referenced from: _AudioIOProc in libportaudio.a(pa_mac_core.o) "_AudioConverterNew", referenced from: _OpenAndSetupOneAudioUnit in libportaudio.a(pa_mac_core.o) "_AudioConverterReset", referenced from: _StartStream in libportaudio.a(pa_mac_core.o) "_AudioConverterSetProperty", referenced from: _OpenAndSetupOneAudioUnit in libportaudio.a(pa_mac_core.o) "_AudioDeviceAddPropertyListener", referenced from: _OpenAndSetupOneAudioUnit in libportaudio.a(pa_mac_core.o) _SetupDevicePropertyListeners in libportaudio.a(pa_mac_core.o) _AudioDeviceSetPropertyNowAndWaitForChange in libportaudio.a(pa_mac_core_utilities.o) "_AudioDeviceGetProperty", referenced from: _PaMacCore_GetChannelName in libportaudio.a(pa_mac_core.o) _PaMacCore_GetBufferSizeRange in libportaudio.a(pa_mac_core.o) _PaMacCore_Initialize in libportaudio.a(pa_mac_core.o) _OpenStream in libportaudio.a(pa_mac_core.o) _AudioDevicePropertyActualSampleRateListenerProc in libportaudio.a(pa_mac_core.o) _AudioDevicePropertyGenericListenerProc in libportaudio.a(pa_mac_core.o) _CalculateFixedDeviceLatency in libportaudio.a(pa_mac_core.o) ...

Any advice?
