I have been including the quicktime framework in one of my programs. Since installing QuickTime 6.0.2, whenever I compile after cleaning the program, I receive warnings in every class I have. These are the warnings:
/System/Library/Frameworks/QuickTime.framework/Headers/QuickTime.h:20: warning: could not use precompiled header '/System/Library/Frameworks/Carbon.framework/Headers/Carbon-gcc3.p', because:

/System/Library/Frameworks/QuickTime.framework/Headers/QuickTime.h:20: warning: 'CarbonSound/CarbonSound.h' has different date than in precomp

Everything works fine when it runs but having errors everytime is annoying. Also, I am including QuickTime just for this function:
void playSound(void)
{
NSString * soundPath;
NSMovie * movie;
NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults];
float volume = [defaults floatForKey:SoundLevelKey];
soundPath = [[[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"Contents/Resources/Alert.aiff"] stringByExpandingTildeInPath];
movie = [[NSMovie alloc] initWithURL:[NSURL fileURLWithPath:soundPath] byReference:YES];
if(movie != nil) {
SetMovieVolume([movie QTMovie], volume);
StartMovie([movie QTMovie]);
while (!IsMovieDone([movie QTMovie])) continue;
}
[movie release];
}

This plays a simple beep and allows to set the volume. Perhaps there is a better way to do this because the volume isn't consistent. The is the application is here. Disregard the terrible graphics and such...Thanks for any help.

Installing QuickTime 6.0.2 invalidates the precompiled headers. Run sudo fixPrecomps and you won't get those warnings anymore (your compile times will be faster, too).


Also, an unrelated tip... you might do well to replace this line:

Code:
soundPath = [[[[NSBundle mainBundle] bundlePath] stringByAppendingPathComponent:@"Contents/Resources/Alert.aiff"] stringByExpandingTildeInPath];

with this:

Code:
soundPath = [[NSBundle mainBundle] pathForResource:@"Alert" ofType:@"aiff"]

It's shorter, guaranteed to give you an absolute path, and will still work if Apple changes the bundle layout.

Kind of silly there's no -setVolume: on NSSound, eh?

Thanks, that fixed all the warnings. It would be a lot easier if NSSound let you set the volume...
