gcc compiler options on MAC OSX

[Scott Driscoll]

Hi, I got the same problems trying to compile the PD plugins under OS X 
(10.4.5) and tried both of the command lines suggested below. 

gcc -bundle -undefined suppress -flat_namespace -o aubio.pd_darwin *.o 

gave me a aubio.pd_darwin (20Kb) that I placed the in the Contents/Resources/Extra directory, but Pd couldn't create any of the objects.  

gcc -bundle -bundle_loader /Applications/Pd-extended.app/Contents/MacOS/Pd -flat_namespace -o aubio.pd_darwin *.o

gave me the following error:

/usr/bin/ld: Undefined symbols:
_post
_aubio_onsetdetection
_aubio_peakpick_pimrt
_aubio_pvoc_do
_aubio_silence_detection
_class_addmethod
_class_domainsignalin
_class_new
_dsp_add
etc...

I'm fairly unfamiliar with building / linking code and using Make files, so I could be making some basic mistakes.  Appreciate any advice or modified Make files that might work for OS X.
