After adding the line
#import <DTPerformanceSession/DTSignalFlag.h>
I get 'libproc.h file not found'. This file is not on my mac. I have tried googling it and it appears is should be included with Xcode. I have tried upgrading xcode from 4.3 to 4.4 and still the same error.
I am trying to use the following line in my game loop.
DTSendSignalFlag("com.mycompany.mytracepoints.app.point", DT_POINT_SIGNAL, TRUE);
I have included the DTPerformanceSession.framework Am I missing something?
