Re: [Discuss-gnuradio] initial gr-audio-portaudio

[Robert McGwier]

Yes. This is an error.  To get started I just manually constructed 
portaudio.pc and started work on gr-audio-portaudio.  After we get the 
appropriate fix to Makefile.in in the portaudio build,  we should open 
gr-audio-portaudio.  It is ready for us all to beat on it and find the 
problems.
