Hello Guix users!
Recently I had an issue when I did a `guix pull`, so I tried `guix pull
--no-substitutes`. My understanding is, that substitutes are platform specific
pre-built binaries, which one can download from the guix servers, instead of
building them oneself. (Please correct me, if this is wrong.) So I thought, that
most time would be spent compiling things and hopefully compiling many things in
parallel as much as possible, to speed up the whole process. However, guix
seemed stuck at some "build phase". I waited for like 2h or so, but it was still
at that build phase. Is this normal? How long does it usually take to run with
no substitutes? I guess it also depends on what one has in ones profile, so here
is my output of `guix pacakge -i`:

Ultimately I canceled the build phase thing and removed a package that caused a
problem to get `guix pull` to work. Would be great to have some estimate though,
whether building without substitute should take around an hour and was simply
stuck somewhere, or takes a day, or maybe even more than a day, so that I could
leave my machine running over night to let it finish. Is it even realistic to
run a pull with --no-substitutes with a 16 core machine, or is that a workload,
which is more oriented towards some powerful server hardware?
Sorry to be this vague about which build phase it was stuck at. I did not copy
the output yesterday and did not screenshot it. I could try again, if needed.
Best regards,
Zelphir

Being similarly vague, I think you did the right thing. Something was
definitely stuck. I also abort such runs from time to time.
On my seven-year old desktop computer with eight cores—but possibly
using just one—I just saw the timing below.
Kind regards

OK, that's a house number. Next time I get a duration above 30 minutes or so, I
might send a less vague report : )
Thanks!

It will take a lot longer to download and build, rather than use
substitutions.
Each package is built one after another, Guix doesn't build them in
parallel AFAIK. If one of the packages in a transaction doesn't build
then the transaction will fail unless you provide the `--keep-going` switch.
Sounds like one of the packages failed to build - so none of the
packages were updated.
It should tell you right in the output which one is failing and give you
a log.
How long it takes a package to compile depends on the size of the
package, the capabilities of your system and how much of your system
you've allowed Guix to use. I find the options for guix build --max-jobs
very useful.
It's pretty variable how long things take: at one extreme Chromium takes
over 10 hours to compile on my poor laptop!
When a build fails the easiest way to see what is happening is to view
the log and go into the environment to see what's happening:
$ guix build --no-substitutes --keep-failed <package>
The section on 'Debugging Build Failures' is particularly useful [0]
I generally do what you suggest and build the smallest subset of
packages myself if there is no other choice (no substitute) - otherwise
I'm just wasting resources - though building Chromium once was fun!
Best of luck,
Futurile
