Unexpected interaction between gobject-introspection and grafts |

Hi team Guix!
I was working on packaging taffybar (https://github.com/taffybar/taffybar),
which depends on haskell-gi (https://github.com/haskell-gi/haskell-gi) -
haskell bindings for goject-introspection capable libraries. While packaging
gi-gdk, I hit this error:
--8<---------------cut here---------------start------------->8---
** (process:23): WARNING **: 00:09:56.407: Failed to load shared library
'/gnu/store/91ar3zh59n19rdn00png5r9hxp3k0y13-gtk-4.8.1/lib/libgtk-4.so.1'

such file or directory

error: in phase 'configure': uncaught exception:

However, confusingly enough the shared library that is referenced by the
typelib exists in my store (and is also included via the gtk package as a
dependency, so I would expect its available during the build). It took me a bit
to realize that the un-grafted gtk package is being used in the typelib, but
really the grafted one is needed.

In the manual "Debugging Build Failures"
(https://guix.gnu.org/manual/devel/en/html_node/Debugging-Build-Failures.html#Debugging-Build-Failures),
it notes that the build environment can be mimicked using guix shell
(explicitly specifying the '--no-grafts' options). Entering this environment
and looking more closely at the gtk package in use, it appears that its typelib
for libgtk references the .so appropriately.

So this all to say that I'm not sure whats going wrong with my build, but I
suspect it has something to do with grafting. Any help appreciated.
Here is my definition of ghc-gi-gtk (the package that causes this build failure
to become apparent):
--8<---------------cut here---------------start------------->8---
(define-public ghc-gi-gdk
(package
(name "ghc-gi-gdk")
(version "4.0.5")
(source (origin
(method url-fetch)
(uri (hackage-uri "gi-gdk" version))
(sha256
(base32
"1pa8vbm931xq3rb9xr441sccga9h1y03lzf6hp2rwkhyhs006hax"))))
(build-system haskell-build-system)
(properties '((upstream-name . "gi-gdk")))
(inputs (list gtk
gdk-pixbuf
ghc-haskell-gi-base
ghc-haskell-gi
ghc-haskell-gi-overloading
ghc-gi-cairo
ghc-gi-pango
ghc-gi-gio
ghc-gi-gdkpixbuf
ghc-gi-gobject
ghc-gi-glib))
(native-inputs (list pkg-config
gobject-introspection-cairo)) ; for GI repository
files (.gir files)
(home-page "https://github.com/haskell-gi/haskell-gi";)
(synopsis "Gdk bindings")
(description "Bindings for Gdk, autogenerated by haskell-gi.")
(license license:lgpl2.1)))
--8<---------------cut here---------------end--------------->8---
I did not include other dependencies that are not yet packaged upstream (eg.
ghc-gi-*, ...), but am happy to provide them if they are useful for
reproduction of this issue.
PS: If you noticed I'm using the package 'gobject-introspection-cairo', this is
because I found that the cairo typelibs are not included in the cairo package,
or gobject-introspection. I worked around this using the aforementioned
variant, which is defined like so:
--8<---------------cut here---------------start------------->8---
(define-public gobject-introspection-cairo
(package
(inherit gobject-introspection)
(name "gobject-introspection")
(inputs (cons* (list "cairo" cairo) (package-inputs gobject-introspection)))
(arguments
`(#:phases
(modify-phases %standard-phases
(add-before 'configure 'patch-cairo-gir
(lambda* (#:key inputs outputs #:allow-other-keys)
(let* ((out (assoc-ref outputs "out"))
(cairo (assoc-ref inputs "cairo")))
(substitute* '("gir/cairo-1.0.gir.in")
(("@CAIRO_SHARED_LIBRARY@")
(string-append cairo "/lib/@CAIRO_SHARED_LIBRARY@")))
#t))))))))
--8<---------------cut here---------------end--------------->8---
Note: this adjustment to gobject-introspection should likely make it upstream
(and was inspired by a similar change to nix (described
https://github.com/NixOS/nixpkgs/pull/34081)).

Thanks Josselin.
I haven't looked at this in some time, so I'm closing to avoid clutter.
