Re: Building pa_wavplay

[Ronan Scaife]

Dear Børge and others,

3 years ago, I ported pa_wavplay to *Scilab*, which has its own 
utilities for
building mex extensions (like those in Octave). All sources for my port
are available at:

<http://elm.eeng.dcu.ie/~scaifer/pa_wavplay/index.html>

In the downloadable sources available from the above page, I think that 
most if not all
of the changes are in pawavplaySW.cpp.

AFAICR, I did NOT build a separate portaudio dll, but just included some 
of the PortAudio
source files in my own front end. Only a few (5 or 6) files from the 
portaudio distro
are needed for pa_wavplay.

You end up with just a single dll: sci_pawavplayw.dll.

It would have been nice to use mingw32 to build the dll, but I was in a 
hurry, so I used
the MS tools, like in the original pa_wavplay.

Best Wishes,
