Heyya.
(SOLVED IN TERMS OF RUNNING BINARY)
Note from several updates - this is more turning up to be a oddball connected to the build methods of ethminer - with the combination of oddball of the AMD GPU PRO and OpenCL implementation connected to it…
(Converting this to a trial-and-error-thread-please-assist-if-you-want-thread, in case someone else ends up with the same issues…)
Been trying this morning and over lunch to smack the AMD GPU PRO drivers with OpenCL onto my Ubuntu 20.04 machine (Yes… I need that or at least something that fires off OpenCL). Reason, running ethminer.
# lsb_release -a
No LSB modules are available.

Backstory would be that I want to play with mining. I’ve targeted ethermine since it was a breeze to get running with my Nvidia-cards and CUDA.
However, it’s not a walk in the park with the AMD portion.
Standard packages, even adding on some that’s already in the standard repo will error out (well, ethminer 0.18/0.19 will -

So, of course I did some google-foo, and ended up with the ‘latest’ AMD driver for my RX580. (20.45 at time of writing) - actual install-params was headless and pro…

However, compiling the dkms-component explodes… (usually, all explodes but dkms-components triggers it…)
$ uname -r
5.8.0-43-generic
After som mashing - I’ve managed to “partially” get it right, (it’s a looong time banging on it and ended up removing for no real reason most of the other stale kernels and reinstalling 5.8.0-43
apt-get install --reinstall linux-image-$(uname -r) linux-modules-$(uname -r) linux-modules-extra-$(uname -r) linux-headers-$(uname -r)
Now, it got a bit more happy - but, the first error is back (instead of just "can’t find a proper gpu to use…).

There’s a long threat I found that goes back a while with the 5.4 Kernel of Ubuntu 20.04,
Last entry confused me quite a bit…
In short - does anyone sit on any kind of pointers? 
I thought the fighting drivers-days were over, but … wrong I was…
(OpenCL … really… this much trouble?)
Odd part - clinfo does print out statements… Perhaps it’s just the software I am trying to run that has the real issues?

Starting to look very much like the build of the binary I am trying to run has some serious issues and has hard AMD OpenCL binary that creates the scenario - I am trying to put my head into building it myself and will either kill this thread if I can figure out that it is the cause, or just see if it’s a joint issue…
(ethminer project link;
Release ethminer 0.18.0 · ethereum-mining/ethminer · GitHub )
Issue created at;
Issue cleared, as far as compiling and running it goes.
As always - thank you Arch Linux users, your documentation is amazing.
https://wiki.archlinux.org/index.php/AMDGPU
This means that after cloning the ethminer repo, and not just downloading the “source” compressed files, compiling works. What I used what to kill off the AMD binary included (and turned off CUDA).
So far final words:
I see this still as a problem but not actively looked at. There’s major issues with AMDGPU Pro as we know. Resolving this lies in the hands of AMD.
Developers going the partially great and partially lazy-turtle route will make things really hard. Including other git repos and forcing an init on those repos before building is just for me awkward. The AMD binary includes (to be dug out as far as I am capable) is an issue for ethminer.
I hope you all can get some useful information from all this.
Thank you for reading :).
