Yeah something is unexpected.
--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix build llvm-cling -d --no-grafts \
| xargs guix drv-show | recsel -p outputs
outputs:
+
/gnu/store/m1z5257hj5vwc2rl47wkpf0wmr6x0bq2-llvm-cling-18-20240227-01-opt-viewer
[opt-viewer]
+ /gnu/store/bg3xs25xyllpzw322sqcc8ipw9q8lph6-llvm-cling-18-20240227-01
[out]
--8<---------------cut here---------------end--------------->8---
But from ’guix repl’
--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> ,pp (package-outputs llvm-cling-2)
$6 = ("out")
--8<---------------cut here---------------end--------------->8---
And the package arguments reads:
--8<---------------cut here---------------start------------->8---
scheme@(guix-user)> ,pp (package-arguments llvm-cling-2)
$5 = (#:configure-flags
#<gexp gnu/packages/llvm.scm:586:6 7f6a06421150>

Concretely,
/gnu/store/rhb3lmkbp5d92c0x0sxkmfwbpbs4b4hp-llvm-cling-18-20240227-01-builder
reads,
--8<---------------cut here---------------start------------->8---
(define %outputs
(list
(cons "out"
((@
(guile)
getenv)
"out"))))
(define %output
(assoc-ref %outputs "out"))

#:phases
(modify-phases
(modify-phases %standard-phases
(add-after

(lambda*

"/share")))
(mkdir-p opt-viewer-share)

(delete

Therefore, the bug comes from an incorrect derivation (drv) file. It
contains an output that it should not.
Well, I have not investigated further… Probably an issue with code
staging (what is evaluated when).
Cheers,
