Hi!

Sorry for the delay in replying.  The options within Playrec when compiled on Mac have not been very thoroughly tested because I have had to rely on other people to try things out.  Therefore it is likely that not all options will necessarily work (the GUI rules out all of those that I knew would definitely not work, but doesn't mean all those available will definitely work).

Do you have a reason to get this compiling with ASIO and/or JACK or were you just trying it to see if it worked?  As you've got CoreAudio working, I believe this should be sufficient for almost all cases.

If you do have a reason to get either ASIO or JACK running then let me know and I'll try and investigate further.

Thanks,
Rob

Hi rjollos,

I had exactly the same problem when trying to compile playrec (OSX 10.5.8, Matlab 2009b, GCC 4.0, Playrec 2.1.1, Portaudio v19) with CoreAudio. After some trial and error and by reading this other post http://www.playrec.co.uk/forum/viewtopic.php?id=68  I actually found a solution that works for me.

The problem is in the linker that does not find a number of symbols which are defined in the frameworks CoreServices, CoreFoundation, AudioUnit, AudioToolbox and CoreAudio. The solution to add the 'extra_flags' from the other post was correct, but mex() must pass these flags only to the linker. So the solution is to add this code at line 108 in the file 'compile_playrec_func.m':

extra_flags = [extra_flags,{'LDFLAGS=\$LDFLAGS -framework CoreServices -framework CoreFoundation -framework AudioUnit -framework AudioToolbox -framework CoreAudio'}];

where LDFLAGS are gcc flags for the linking phase (see also this post in the Matlab forum: http://www.mathworks.de/matlabcentral/n … ead/148409 ).

Hope this is useful for you.

Cheers
Marco
