2.6.6 MacOS X additional notes

These random notes might be useful for OS X users.

Qt

On MacOS X and when using Qt-4.3.0 or higher, you must add:

     export QMAKESPEC=/usr/local/Qt4.3/mkspecs/macx-g++/

to your ~/.profile or ~/.bash_profile and then close (and re-open) your terminal window before compiling Marsyas.

Recording audio

When trying to record audio, the sample rate must be specified explicitly:

     pnet->addMarSystem(mng.create("AudioSource", "srcRec"));
     pnet->updctrl("mrs_real/israte", 44100.0);
     pnet->updctrl("AudioSource/srcRec/mrs_bool/initAudio", true);
MATLAB

These instructions have been tested on OS X 10.5.8 and MATLAB_R2009a.

  1. MATLAB and X11 for OS X must be installed
  2. The naming conventions of MATLAB are a messy so the CMake configuration assumes that either the MATLAB environment variable is set or looks for MATLAB in /Applications/MATLAB_R2009a.app
  3. Compile Marsyas and enable the WITH_MATLAB option. If MATLAB can not be located you will get an error message. Try setting the MATLAB enviornment variable and if that does not work then attempt to set the paths to the MATLAB-related variables manually.
  4. You will need to edit your .bash_profile with the following lines:
              export MATLAB="/Applications/MATLAB_R2009a.app"
              export DYLD_LIBRARY_PATH=$MATLAB/bin/maci/:$MATLAB/sys/os/maci/:$DYLD_LIBRARY_PATH
    
  5. try out mudbox -t MATLABengine. MATLAB should open and various benchmarks and communication between Marsyas and MATLAB should happen. If not email the mailing lists for some help.
