Re: [Discuss-gnuradio] More On Ticket 141

[Michael Dickens]

Got it!  It's the line:

swig_CXXFLAGS="-g1 -O1"

in "gnuradio/configure.ac".  Changing this to "-O2" does the trick.   
I've created a branch at < http://gnuradio.org/svn/gnuradio/branches/ 
developers/michaelld/t141 > with the change.  I don't think it will  
affect any other os except Darwin ... hope I got the syntax correct.   
It works for me.  Here's the svn diff:
