You can investigate if the analyzer is triggered on your code by adding a function with a bug in it and analyzing the code base.
Ex: Add the following function and run XCode->Product->Analyze:
int foo(int x) {
  if (x == 0)
    return 5/x;
  return 10/x;
}

I am not sure exactly how you are analyzing from command line, but the error you are getting is probably due to mismatched versions of XCode and the analyzer.

There is also an option in the XCode Build settings called "Run Static Analyzer", which would enable the analyzes during the build.
