Hi, I tried to compile gnuradio 3.6.3 on MacPorts with the following
command:
sudo port install gnuradio +docs +grc +orc +python27 +qtgui +sdl +swig
+uhd +wxgui configure.compiler=macports-gcc-4.7
GNU Radio was installed successfully on my quad-core Core i7, but when I
execute GNU Radio Companion signal flow, I see the following messages:
_____ Message _____
Mac OS; Clang version 4.1 ((tags/Apple/clang-421.11.66)); Boost_105100;

gr-osmosdr supported device types: file fcd rtl rtl_tcp uhd

How can I make gnuradio and volk be optimzed for Core i7? generic_orc
seems not best optimized for core i7.
Thanks in advace!
Sincerely,
Albert
