Setting up OpenFrameworks/iOS to work with RTcmix

This will use the latest (0.8.4 as of this doc) OpenFrameworks package for iOS. Hopefully this will be updated soon, because 0.8.4 OF/iOS does not support 64-bit development. I believe the iOS App Store now requires this capability for app approval, so I expect that the OF community will deliver a 64-bit-capable development environment soon.

• 1. Download the of_v0.8.4_ios_release.zip file and double-click to unzip it.
  
  
• 2. If you want, you can check the OF download by going into the [your location]/of_v0.8.4_ios_release/apps/myApps/emptyExample directory and double-clicking on the emptyExample.xcodeproj file.
  
  
• 2a. If you try to build and run the "emptyExample", it will probably fail because the 64-bit architecture is not included. You can circumvent this problem by putting these lines of code:

  extern "C"{
      size_t fwrite$UNIX2003( const void *a, size_t b, size_t c, FILE *d )
      {
          return fwrite(a, b, c, d);
      }
      char* strerror$UNIX2003( int errnum )
      {
          return strerror(errnum);
      }
      time_t mktime$UNIX2003(struct tm * a)
      {
          return mktime(a);
      }
      double strtod$UNIX2003(const char * a, char ** b) {
          return strtod(a, b);
      }
  }
  

  in the "main.mm" file right after the

  #include "ofMain.h"
  #include "ofApp.h"
  

  lines at the top of the file. This will not fix the underlying 64-bit App Store issue, but it will allow the code to run.
  
  
• 3. Now download the basicRTcmix-iOS-Xcode6.1.1.zip file and double-click to unpack it. Move the "basicRTcmix" folder to the [your location]/of_v0.8.4_ios_release/apps/myApps/" directory, so that it is at the same level as the "emptyExample" folder.
  
  
• 4. Go in an fire up the "basicRTcmix.xcodeproj" file and off you go! Note that the '64-bit workaround' lines in "main.mm" are already included. You should be able to run this on the simulator AND on your devices if you have registered them with the annoying Apple iOS Developer program.
