Hi Ryan - I just did a clean uninstall, git pull, then reinstall of the current
master; I don't see this issue at all (e.g., the "dial_tone.py" example works
just fine -- though I don't know which audio interface is being used). I'm
running 10.6.8 on a MacBook Pro (early 2009 model), 64-bit kernel, using XCode
3.2.3 (Apple GCC 4.2.1 build 5664). I installed all background dependencies
using MacPorts (roughly: "sudo port install gnuradio" and then disabling all of
the GNU Radio ports, leaving just the dependencies).
If I do "nm -a /usr/local/lib/libgnuradio-audio-3.4.1git.0.dylib | grep
_Audio", I see (correctly) "U _AudioComponentFindNext" (among others). If I do
"otool -L /usr/local/lib/libgnuradio-audio-3.4.1git.0.dylib", I see (among
others in the list)
"/System/Library/Frameworks/CoreAudio.framework/Versions/A/CoreAudio" and
"/System/Library/Frameworks/AudioUnit.framework/Versions/A/AudioUnit" and
"/System/Library/Frameworks/AudioToolbox.framework/Versions/A/AudioToolbox".
Now, admittedly, I also have JACK and PortAudio installed -- so those might be
providing the libraries instead of having them linked in just for (the old)
gr-audio-osx code; I'll try testing with just the OSX audio & see what happens.
Does the provided patch (doing "+LDFLAGS = -framework AudioUnit -framework
AudioToolbox") work for you? - MLD
