when I try to build volk from next branch of git, I got error during make
libtool: link: gcc -dynamiclib -Wl,-undefined -Wl,dynamic_lookup -o
.libs/libvolk_runtime.0.dylib .libs/volk_cpu_x86.o .libs/cpuid_x86_64.o

ld: duplicate symbol _volk_cpu in .libs/volk_runtime.o and .libs/volk_cpu_x86.o
collect2: ld returned 1 exit status
make[2]: *** [libvolk_runtime.la] Error 1
BTW, I did it on OSX 10.6.5
Im no expert by any means but this is usually caused when something is
defined twice in two different .c files. So looking into it it appears
that way, so I added the static keyword so that each file can use the
definition but they wont interfear with each other.
proper #ifdef should prob be used but this was quick and dirty and got
me compiled and up and running on OSX

We’re working on trying to fix this. The patch that was submitted does
not actually work. When I run it with the patch, the resulting
architectures that VOLK will build for is only the ‘generic’ one, not
all of what should be built (on my Core2Duo: generic 64 mmx sse sse2
sse3 ssse3).
I only think that I might know why at this point. It shouldn’t be hard
to fix once I get my head wrapped around it properly.

Chris,
I believe what I just pushed to the next branch should fix your
problem with VOLK. Michael D. was able to help me out by testing
it on his OSX machine. Let me know if you have any more problems.
