Re: [Discuss-gnuradio] building GNU Radio from tarball on Mac Os X with gcc-4.7

[Michael Dickens]

Hi Arturo - You're getting further than I am :) .  I've just tried doing the 
build using MacPorts gcc-4.7 and gcc-4.6, with the 3.6.4.2 release as well as 
the latest maint and master branches.  Every one of them errors out as follows:

volk/lib/volk_cpu.c:54:no such instruction: `xgetbv'
make[2]: *** [volk/lib/CMakeFiles/volk.dir/volk_cpu.c.o] Error 1
make[1]: *** [volk/lib/CMakeFiles/volk.dir/all] Error 2
make: *** [all] Error 2

So, apparently these versions of GCC (4.6.4 and 4.7.3), at least on MacPorts, 
do not recognize the 'xgetbv' instruction.  We've had this issue in the past 
with OSX compilers, but obviously it has not been resolved.

Do you know how you got past this error?  Or, did you just not get it? - MLD
