The cryptic error message is about an unexpected character, namely
(specifications->manifest ’ <- this backtick
It needs to be the ascii >'<.
If you fix that, you get new errors.
If you read the info page "Writing manifests", you'll see you have to
use the package names like when using `guix package -i musescore` etc.
when using specifications->manifest.
guix search musescore would show you under `name:`, that the musescore
package (in guix) is named in lowercase. Also OBS Studio is called obs,
vlc is called vlc etc.
But you can not add cmdline args like --with-branch.
For that you need to instead create a new package definition for
musescore version 3.6.2. The info page gives you an example, which you
just adjust. Using guix edit musescore you see how musescore is defined.
You can notice, there is a version field. So lets create a new package
with adjusted version:
(define musescore-3.6.2
(package
(inherit musescore)
(version "3.6.2")))
;; We create this manifest from a _package_, and not from a
;; _specification_ (which is just something like a string "musescore")
(packages->manifest (list musescore-3.6.2))
So now putting everything together:
;; Manifest Musik Programme
(use-modules (gnu packages music)
(guix packages))
(define musescore-3.6.2
(package
(inherit musescore)
(version "3.6.2")))
;; combine both manifest lists:
(concatenate-manifests
(list
(packages->manifest (list musescore-3.6.2))
(specifications->manifest '("ardour" "audacious" "audacity" "obs"
"vlc"))))
