Re: [Discuss-gnuradio] GNU Radio Using MacPorts

Hi all,

I've tried (in Mac OS X 10.8.2, Xcode 4.5.2 with up-to-date Command Line Tools):

$ sudo port install gnuradio +grc +python27 +uhd +orc +swig configure.compiler=llvm-gcc-4.2

Everything built smoothly. Now when I do volk_profile, the sse implementations are there and accelerate some volk instructions considerably. I'm happier than a kid in a candy store :-)

Hi Carles - Thanks for the report; I'm glad it works for you!  If you installed the "gnuradio" port using XCode 4.5 or newer (maybe even 4.4 or newer), then Apple's Clang is the default compiler suite.  IIRC, Volk and Clang do not play nicely together yet; Volk (at least as of the 3.6.2 release) will enable SSE and related instructions when compiled using gcc only.  Which you can do if you want to IIRC by appending "configure.compiler=apple-gcc-4.2" to the end of your "sudo port install …" command line. Or, you could choose "llvm-gcc-4.2" instead which should also work.  I haven't tried either of these yet, so if you do I'd love to hear about what happens. - MLD
