[Discuss-gnuradio] gnuradio volk compilation er ror: error: ‘_mm_popcnt_u64’ was not decla red in this scope

[Ruben Merz]

Hi all,

I started a fresh build from the branch next of gnuradio (revision 
1047775464c1bb8a86e727487551e2b14abd476e).

Compilation currently fails within volk:

In file included from qa_64u_popcnt_aligned16.cc:4:
../include/volk/volk_64u_popcnt_aligned16.h: In function ‘void 
volk_64u_popcnt_aligned16_sse4_2(uint64_t*, uint64_t)’:
../include/volk/volk_64u_popcnt_aligned16.h:45: error: ‘_mm_popcnt_u64’ 
was not declared in this scope

I've tried including directly smmintrin.h in volk_64u_popcnt_aligned16.h 
but that did not work either.

My machine is using Ubuntu 10.04 LTS (32 bits version), gcc 4.4.3, 
autoconf 2.65.

CPU is an Intel quadcore i7 930.
