Unable to compile for GNU Radio 3.8 on Ubuntu 22.04

Hello,

I am trying to set up a ground station that depends on GNU Radio 3.8 (some custom OOT modules have not been ported yet).

Since I'd like to avoid being stuck on Ubuntu 20.04, I am compiling GNU Radio 3.8 from source on 22.04. This is all running in a docker container on an amd64 host. I will include relevant parts of the Dockerfile below. From what I can tell, the program is being built successfully.

Unfortunately I am unable to compile gr-satellites on 22.04 with my self-compiled GNU Radio, it worked just fine on 20.04 with the GNU Radio version from the repository. It appears that the compiler is unable to find Volk?

The VolkConfig.cmake files seem to be in the correct location:

root@826ea153cfd1:/usr/local/lib/cmake/volk# ls
VolkConfig.cmake  VolkConfigVersion.cmake  VolkTargets-release.cmake  VolkTargets.cmake

I can also see libvolk.so and libvolk.so.2.0 in /usr/local/lib.

I have to admit that I'm not very familiar with C, I don't really understand how the build scripts work, so I'm thankful for any help.

As promised, here is my Dockerfile:

Have you checked that volk/volk_alloc.hh is installed somewhere (maybe in /usr/local/include)? If that's the case, then it looks like gcc isn't getting the right -I flag for the include path (say -I/usr/local/include), though I don't know why cmake isn't setting that up correctly, given that it doesn't complain that it hasn't found Volk.

Hi, thanks for your reply!

The folder /usr/local/include/volk/ exists, but interestingly volk_alloc.hh is missing. Instead, I see a volk_malloc.h. Is this a case of incompatible versions/dependencies?

Apparently volk_alloc.hh first appeared in Volk 2.1.0. In the main-3.8 branch of GNU Radio, the volk submodule points to Volk 2.0.0, so that's probably the version of Volk that you've built and installed. On the other hand, Ubuntu 20.04 ships with Volk 2.2.1, so that's the reason why the CI of the maint-3.8 branch of gr-satellites, which builds against Ubuntu 20.04's GNU Radio and Volk isn't hitting this problem.

That's interesting. So what's the best way to proceed now? Can I just manually move the volk submodule to 2.2.1 before compiling? Or do you have any other suggestions for running on 22.04? (The only reason I'm compiling from source is because I cannot find a PPA for GR 3.8, I don't need the flexibility of compiling myself)

My advice would really be to move away from GNU Radio 3.8 and use GNU Radio 3.10 instead, because GR 3.8 is unmaintained and outdated. Whatever OOT modules that you're using that depend on 3.8 should be ported to 3.10. Otherwise they're just technical debt.

But if you really want to stick with GR 3.8, then pointing the volk submodule to whatever version you want to use seems a valid approach. It's been a long time I don't use GR 3.8, but I can't think of a reason why it shouldn't work with even the latest stable release of Volk.

I fully agree, I'd also like to move on from 3.8. Unfortunately it's not my project and I have no experience with the development of OOT modules. I'm just tasked with making it work.

For now, I've updated volk to 2.1 (I was having some issues with a later version) and it's compiling now. Thanks for your help!

For reference:

cd volk
git fetch --tags && git checkout v2.1.0
