What version of the product are you using? On what operating system?

   Windows XP
   Python 3.3

Please provide any additional information below.

I have since installed Python 2.4 
(http://www.python.org/download/releases/2.4.4/ ) and Python 2.7 (). This work 
better, but I still get errors ...

Hi, I am not sure if the code for google-styleguide is still being maintained - 
there seems to be low activity. I do not want to push this issue if it is 
unrealistic that it will be fixed - I know most of these projects are supported 
by people busy on their own work!

I am wondering if my problem is due to a bad installation of tools or Python?

I am having the exact same problem here, using Win7 and r99 (the latest 
revision) of the python scripts and Python 3.3.
Additionally, the cpplint.py script itself produces an empty output when run on 
any file.

Same here. Linux works fine, while Windows gives empty output.

Wrong version python for cpplint.py. Version 2.7 works fine, while version 3.4 
does not. One of functions I found not supported is the xrange.

change

comment the line in the main() function where sys.stderr is reasigned

.itervalues() to .values()
.iteritems() to .items()
xrange(..) to range(..)

redefine GetLineWidth
def GetLineWidth(line):
  return len(line)
