Marcus,
Is this a new installation of Ubuntu? I’ve installed this on many
machines
using Ubuntu 10.04 and 10.10 without a problem. I’m guessing (hoping?)
that
this is related to an unknown dependency. It almost seems like you don’t
have the SSE intrinsics installed. Maybe there’s some part of a
developers’
package that you don’t have?
If you find that it’s a missing dependency, let me know and we’ll add it
to
things to look for and to install.

It’s an Athlon XP2500 machine, which apparently has SSE, but no SSE2.
That’s it, all right. volk_common.h defines a union which includes
__m128i, which is only defined in SSE2 (emmintrin.h) and higher – but
the test Volk uses for this union is only (if LV_HAS_MMX). That test
should be (if LV_HAS_SSE2). Ordinarily, on SSE2 machines, there’s an
#ifdef at the end of xmmintrin.h which includes emmintrin, where __m128i
is defined.
I don’t know what making that change will break on non-SSE2 machines;
can you try it?

Funortunately, it’s not my machine. I was asking on behalf of a
customer, who has decided to go off and
purchase a more-modern machine, which likely has “all the microcode
bells and whistles” 
But we do need to deal with this for older, non-SSE2-or-better machines.

I agree, and this looks like a mistake. Wish we had the machine to test
it
