I'm seeing code like this

#ifdef JAVAAXDEBUG NSLog(@"%s: %@", FUNCTION, value); #endif What is the correct way to turn on a definition? #define JAVAAXDEBUG 1 Thanks Mike, What I meant was, can I do something like -DJAVAAXDEBUG when invoking make?

I'm not sure - does a Make expert know what the exact syntax is?

I'm also seeing NSLogs which are not bracketed with a define. Does NSLog always output to stdout or does it need a switch of some sort? NSLog goes to both stderr and the ASL database (which Console.app shows and lets you query). I see lots of logs in /Library/Logs. Is one of these the "Java" log?

No, Java applications are not categorically all logged together. You'll have the most success just reading stderr and ignoring the ASL database. I only mentioned it for technical completeness.
