And I didn’t find any helpful information on this and look forward for
help.
What’s more, installing GNUradio-3.7 on 32-bit Ubuntu under 64-bit
computer will meet other test failure.

Hi Howard,
Although I do not know the reason of this problem clearly, I think
installing Ubuntu 64-bit system on a 64-bit CPU processor may be a good
choice. A few months ago, I faced the same problem as you, strange
things
happened to VOLK (or something) when a 32-bit system run on a 64-bit CPU
processor. I tried a pile of methods to solve it. Unfortunately, all of
them failed. So I installed the 64-bit Ubuntu system and all things go
well.
Of course, this is not a good solution. I want to know the specific
reason
and the way to solve it either.

I /thought/ we had solved the 32-bit OS on a 64-bit platform with
VOLK, but it is a particularly nasty issue. I know our 32-bit VMs on
64-bit systems works fine now. But this problem is difficult because
it’s a fairly rare setup these days. Most things are now 64-bit
compatible, so unless you have a /very/ specific reason for using a
32-bit OS, my recommendation is to update to 64-bit. It’d still be
nice to not have this problem, but I just don’t see the benefit of a
32-bit OS these days.

Hi YiZiRui,
if this is really the case, this would constitute a bug - VOLK kernels
should work on 32bit machines too, although there might be
instructions that only appear on CPU’s that support 64bit anyway.
However, nowadays it surprises me that people install 32bit linuxes on
modern machines at all; having more than 3.2GB of RAM is rather usual
today but not (natively) possible with 32bit OSses.
With respect to make test fails: Bugs are fixed on a daily basis, and
a lot of things are happening in VOLK right now, so the fails on a
64bit machine might not really be os-dependent…
Greetings,
Marcus
