Subject: Build failure with installed guix that does not happen with pre-inst-env

Dear Guix experts,

When updating my Guix installation after three weeks of absence, I
noticed a build failure:

   $ guix pull –commit=de596e99549d7764f370ab2ed3b756f620b1f23d
   $ guix build racket

   guix package: error: racket-fix-xform-issue.patch: patch not found

However, that patch file is there:

   $ ls -l .config/guix/latest/gnu/packages/patches/racket-fix-xform-issue.patch 
   -r--r--r-- 10 root root 2520 janv.  1  1970 .config/guix/latest/gnu/packages/patches/racket-fix-xform-issue.patch

Moreover, the same build works fine when I check out the same commit and
use pre-inst-env:

   $ cd ~/Development/guix
   $ guix environment guix
   $ git pull
   $ git checkout de596e99549d7764f370ab2ed3b756f620b1f23d
   $ ./bootstrap
   $ ./configure --localstatedir=/var
   $ make
   $ ./pre-inst-env guix build racket

I suspect that this is somehow caused by the new implementation of "guix
pull", but I don't know how I would go about debugging this, so I defer
to the experts.

Konrad.

Hi Konrad,

thanks for the precise error report.

Could it be the case that in your `guix build ...` you are not using
the guix you pulled?

What does `guix --version` say?

Where does `which guix` point to?

It should point to

~/.config/guix/current/bin/guix

I suspect you have an older version of Guix (i.e. "before the new
implementation") in your $PATH with a higher precedence (more to the
beginning of the $PATH variable). See what `echo $PATH` says. If that
is the case, adapt your path.

HTH,

Björn

Thanks for your quick reply!

It points to $HOME/.guix-profile/bin/guix, and since I have the package
"guix" installed in my profile, that looks OK to me. At the very least I
am used to it: guix has always been in my profile, and has always worked
well that way.

But I do see how this could cause various failures after a guix pull,
because the guix in my profile has to work with the updated stuff the
pull has placed under ~/.config. So perhaps the real mystery is that I
haven't had any trouble before. And I wonder what strategy to adopt to
avoid it - remove guix from my profile? There was a good reason to
install it last year, but I don't remember what it was. If installing
guix into a profile is not a good idea, perhaps the guix package should
disappear or be renamed to something that indicates its true purpose?

BTW, since I updated my profile with the pre-inst-env guix, I now also
have a new guix in my profile and the build failure has disappeared.

Konrad.

You're experiencing the change to the (not so) new guix pull. Now a
complete guix is installed in ~/.config/guix/current. The guix
installed in your profile doesn't look for packages in that directory,
but uses its own definitions. This has a side-effect: whenever you try
to update your profile, not only does your guix not use the newer guix,
but the only guix package it knows of is a least 1 commit *before* your
current guix, hence downgrading guix (and package definitions) at every
update.

Make sure you uninstall guix from your profile and add
~/.config/guix/current/bin to your PATH. Then you should be able to use
the freshly pulled guix.

Hi Julien,

I missed your reply because it arrived while I was on vacation, so I was
made aware of it only by the message about the bug being closed.

Thanks for your clear explanation, I will uninstall guix from my
profile!

Konrad.
