You may want to experiment with compiler flags. Try this: cmake -DCMAKE_CXX_FLAGS:STRING="-mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -g" -DCMAKE_C_FLAGS:STRING="-mcpu=cortex-a8 -mfpu=neon -mfloat-abi=softfp -g" <gr_source_dir> -josh > > > 2011/10/20 <discuss-gnuradio-requ...@gnu.org> > > >> Message: 10 >> Date: Wed, 19 Oct 2011 18:43:32 -0700 >> From: Tom Rondeau <trondeau1...@gmail.com> >> To: GNURadio Discussion List <discuss-gnuradio@gnu.org> >> Subject: [Discuss-gnuradio] New build structure!
