What about `git status`? Is the worktree in a consistent state? Thispatch file was removed in August 2017 [0] and nothing should refer to itanymore.

Thank you Leo.
I deleted ./gnu/packages/qemu.go and re-ran make.
Make failed to regenerate ./gnu/packages/qemu.go
So now I am really confused.

The 'gnu/packages/qemu.scm' file was removed from Guix in July 2017,with commit 59132b800093e486e4d81aed6b837e9ac76aa86c. The QEMU packageswere moved into 'gnu/packages/virtualization.scm'.
I'm not an Autotools expert, but in cases like this I usually try `makeclean && ./configure --localstatedir=/var && make`. Did you trysomething like that yet?

Thanks Leo.
I did a new git pull and a clean build as you suggested (please see thegrep of the make.log below for details)
Now when I try 'guix system build sys.scm I get ...
guix system: error: failed to load 'sys.scm':ice-9/boot-9.scm:2795:6: In procedure resolve-interface:ice-9/boot-9.scm:2795:6: no code for module (gnu packages qemu)
... please see details further below. Obviously something is calling'gnu/packages/qemu.scm' but I don't understand what.

Can you post your sys.scm? It sounds like you might have a references to(gnu packages qemu) listed there.

Yes Efraim, that was it. Actually, Leo mentioned that qemu had moved(above) but I failed to realize the implication for the config file.

The usability of Guix configurations
(name . Guix-devel)(address . guix-devel@gnu.org)
868tfjw4is.fsf@gmail.com
My system recently broke when I did an upgrade. I reported what Ithought was a bug (bug#29072) but it turned out that, because qemupackage code had been moved, my system configuration had become broken;-(
Confronted with my situation, helpful developers said "The package codewas moved in commit xxx" (Leo) and "maybe you have a mistake in yourconfig (Efraim)."
Once I understood what had happened I wondered, "Gee, I have been usingguix for 18 months so why didn't I figure this out myself." ;-)
But a less committed user might say, "Wow, Guix breaks at random, errormessages are hard to understand, and support is difficult." :-(
ISTM this raises issues and questions about Guix configurationusability:
Guix config errors are reported as raw scheme errors which are notuser-friendly, except, perhaps, to guile users ;-) Could we improve thissituation by adding config troubleshooting guidance to the doc?
Guix config errors consume meaningful amounts of user and supporteffort. I say this because a) it took quite a few iterations to figureout what was wrong in my situation, and b) google search for '"no codefor module" guix' finds 613 hits, which will no doubt grow linearly withnumber of Guix users unless something is done. So I wonder, could anerror handler that translates into more user-friendly terms reduce userfrustration, increase the rate of user self help, reduce support load,and effectively pay for itself?
Are the current Guix config errors usable by the average GNU/Linuxdistribution user? If not, don't they need to be improved before we callit 1.0? Does this mean that package code must not be moved after 1.0?
Finally: Should I close bug#29072? ;-)

I'm sorry that my comment was not enough on its own!

Good point.

Yes, we do try to add helpful error messages, although obviously thereis a lot more work to be done.
As far as I can tell, the issue was related to the fact that you areusing Guix by building it from source and re-using the same builddirectory, which may contain stale compiled .go files. In this case,there was a leftover qemu.go, which shadowed the correct file,virtualization.go.
This is a useful development technique but not how Guix is supposed tobe deployed and updated. `guix pull && guix package --upgrade` is stillwhat we recommend and support.
If you want to deploy Guix by building it "by hand", I recommend using afresh Git checkout and directory each time you build it. That way, youcan be sure to avoid this class of error (stale module references inleftover .go files), which is well-known to the seasoned Guix developersbut totally confounding for everyone else.

That would be awesome!

Based on how much time it's possible to spend on IRC helping people, I'dsay there is lots of room for improvement in this area.
Toggle quote (2 lines)> Does this mean that package code must not be moved after 1.0?
A couple thoughts... it would be nice if the GuixSD configurationexample templates used a filename agnostic method of resolving moduleimports. I'm not a strong enough Schemer to evaluate the situation orsuggest a solution, but I think that the filenames should not berelevant at that level. Perhaps one could use'specification->package+output',as demonstrated in the documentation of package manifests:
https://www.gnu.org/software/guix/manual/html_node/Invoking-guix-package.html

The problem of the missing QEMU patch is resolved. The broader issue ofconfusing error messages could be continued here, or elsewhere. It's upto you :)

Hey Leo,
Please understand that don't mean this as a complaint your reply, whichwas helpful and I was very happy to receive.
I am just trying to step back and think about the bigger picture.

I didn't mean this point critically. Rather as a statement of fact. WhenI said ...
Toggle quote (3 lines)>> Could we improve this situation by adding config troubleshooting>> guidance to the doc?
... I was thinking something like ...
vvvvvvvvvvvvvvvvvv
Troubleshooting your config file:
If you get an error like:
ice-9/boot-9.scm:[...] no code for module (gnu packages <package name>)
You have either specified a package name that does not exist, or your(use-package-modules <package module names>) does not contain the nameof a package module that contains the definition of <package name>.
You can determine which, if any, module contains a package definition byyada yada yada
^^^^^^^^^^^^^^^^^^
... thinking that then there would be a search hit in the doc for 'nocode for module' which might enable some users to understand what theyare doing wrong.
WDYT? - George

It should be noted that you were using a “developer setup”, specificallyrunning Guix from a checkout with ./pre-inst-env and all.
The issue with the stale module wouldn’t happen with “guix pull”, whichis the recommended “user setup.”
While I agree the situation is not ideal, I think we have to admit thatdevelopers can always shoot themselves in the foot, and that was one wayof doing it. ;-)
Thoughts?
