Trouble building (32-bit Linux, volk-related?)

Hi all,

I’m having trouble building gnuradio from git on my 32-bit Ubuntu 10.10
machine. The error I’m getting is:

$ make

I successfully built and installed from git late last year without any
problems, so my first thought was that I had old code lying around
screwing things up so I deleted my whole gnuradio source tree and git cloned a new one to no avail. I also get the same error if I git checkout any of the v3.5 tags so I don’t think it’s a recent code
change that’s broken things.

I assume this means there’s something wrong with my system - does anyone
have suggestions as where to look?

Thanks,
Ian Cullinan

What version of Orc is installed on your system?

I just pushed a fix for this. Cmake now tests for the version number and
autotools has been updated to check for the same version number.

Ok, now CMake builds volk without orc support and it seems to work.
Given that there isn’t an updated orc package for Ubuntu 10.10, what’s
the recommended course of action?

a) Live without orc support. Does it make much of a difference on x86?
The build-gnuradio script does not install or check for liborc.

b) Install orc from source. Messy, and causes problems if you later
install a package with a dependency on liborc.

c) Install a newer liborc package from a PPA. A quick search of
Launchpad didn’t find any.

d) Get a newer distro. Personally I’m not ready to deal with this yet,
and I suspect many users feel the same way because Ubuntu 10.10 is the
last pre-Unity version.

Thanks,

Ian

That may not be an acceptable version of orc, given that volk seems to
be using some features not in 0.4.6. I might recommend this change:

diff --git a/volk/cmake/FindORC.cmake b/volk/cmake/FindORC.cmake
index 8d8c2d1…1c4c417 100644

Perhaps your URL is typo’d, or you pasted the URL from the wrong tab

Many of the volk kernels have SSE* implementations. So for x86, orc
doesnt give much benefit. But on a platform like arm, orc gives you neon
optimized routines where there were no neon specific kernels
implemented.

b) Install orc from source. Messy, and causes problems if you later
install a package with a dependency on liborc.

c) Install a newer liborc package from a PPA. A quick search of
Launchpad didn’t find any.

You may just be able to snag the liborc debian package from ubuntu
11.10. It only requires libc6, so it should be a harmless package
upgrade.

d) Get a newer distro. Personally I’m not ready to deal with this yet,
and I suspect many users feel the same way because Ubuntu 10.10 is the
last pre-Unity version.

One of the problems is that Orc is still new and went through quite a
bit
of churn last year. There hasn’t been an update in a while, so it looks
like things are maybe stabilizing. But we obviously needed some newer
features, so we had to push the acceptable version number up.

a) Live without orc support. Does it make much of a difference on x86?

Yeah, on x86 machines, you’ll be fine.

b) Install orc from source. Messy, and causes problems if you later
install a package with a dependency on liborc.

I put a link to the download page at:
http://gnuradio.org/redmine/projects/gnuradio/wiki/Volk

I do this on my 10.10 machine.

c) Install a newer liborc package from a PPA. A quick search of
Launchpad didn’t find any.

d) Get a newer distro. Personally I’m not ready to deal with this yet,
and I suspect many users feel the same way because Ubuntu 10.10 is the

Ubuntu 11.10 uses Orc 0.4.14. And you can remove/replace Unity and make
it
use Gnome 2.

Thanks,
