Subject: [bug#76899] Request for merging "c++-team" branch
Date: Fri, 25 Jul 2025 16:15:24 +0200

Hello,

this branch is now first in line.
Could you rebase it on master, possible a commit known (in an hour or two)
to data.qa.guix.gnu.org, or for the time being just commit
   eb7fb3c59d8de06ef942dce55ceb9565917e7ddb
which is the merge of qt-team?

And maybe add the commit of https://codeberg.org/guix/guix/pulls/1569 on top.

Right now QA shows a lot of blocked packages:
   https://qa.guix.gnu.org/branch/c++-team

And CI failed with this message, inside
   https://ci.guix.gnu.org/eval/2073835/log/raw

(exception unbound-variable (value #f) (value "Unbound variable: ~S") (value (cmake-next)) (value #f))
builder for `/gnu/store/sfff5zisrfw5r5s8dw5gsdwm413jdkr7-guix-package-cache.drv' failed to produce output path `/gnu/store/5b2bcrf30gh2q3rpzinq6ri1sxb1lnp1-guix-package-cache'
cannot build derivation `/gnu/store/dzz0dd83pz4gx76rbhzp7zdz9b0x1354-profile.drv': 1 dependencies couldn't be built

I wonder if this indicates a problem with the branch, cmake-next is
definitely a package related to changes in this branch:
grep cmake-next gnu/packages/*.scm
gnu/packages/video.scm:      #:cmake cmake-next                ;needs cmake >= 3.28
gnu/packages/xdisorg.scm:      #:cmake cmake-next
So I think this is a place where cmake-next used to be used, but
it does not exist anymore.

See this commit:

I think this is a place where textual git rebases do work, but are not
semantically correct; we will need a fixup to the commit that removes
cmake-next to handle these two packages.

Thanks,

Andreas
