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:

Toggle snippet (7 lines)

** (process:23): WARNING **: 00:09:56.407: Failed to load shared library '/gnu/store/91ar3zh59n19rdn00png5r9hxp3k0y13-gtk-4.8.1/lib/libgtk-4.so.1' referenced by the typelib: libgtk-4.so.1: cannot open shared object file: No such file or directory

Could not resolve symbol "gdk_device_pad_get_type" in namespace "Gdk-4.0"

CallStack (from HasCallStack):

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.

Toggle snippet (8 lines)

? guix build --no-grafts gtk

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.

Toggle snippet (7 lines)

? guix shell --no-grafts -L . -C -D ghc-gi-gdk binutils

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):

Toggle snippet (31 lines)(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

    (build-system haskell-build-system)
    (properties '((upstream-name . "gi-gdk")))
    (inputs (list gtk
                  gdk-pixbuf
                  ghc-haskell-gi-base

                  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)))

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:

Toggle snippet (18 lines)(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))))))))

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)).

These errors can also be caused by dependent libraries not being found,

or linker errors, etc. I would suggest to run `ldd` on the .so itself

(from glibc), and see what the output is.

Grafts are applied after all packages have been built, so it is normal

that the build environment would see and use the ungrafted gtk.

Best,

Josselin Poiret

Hi Josselin,

Thanks for your quick reply. It appears that all dynamic libraries referenced by libgtk.so are correctly referenced (and not missing):

You'll noticed linux-vdso.so.1 doesn't reference a file but afaik this is expected as its a virtual library provided by the kernel.

This doesn't appear to be the case. Did I miss something?

Yes, but that makes the error all the more confusing; the original error says that it can't find "/gnu/store/91ar3zh59n19rdn00png5r9hxp3k0y13-gtk-4.8.1/lib/libgtk-4.so.1", however this is the ungrafted gtk package, so it SHOULD (afaik) exist throughout the build. Further, when I enter a simulated build environment, the file does indeed exist.

Thanks again for you ongoing help and support!

Hi Collin and Josselin,

I haven't fully read this thread but wanted to chime in with work I did

but never finalized to upstream here. In short, I did get taffybar to

build and run if I recall. There was a lot of fussing with versions,

some Haskell packages that were broken/undergoing some breaking changes

at the time...I don't remember the details, sorry.

https://gitlab.com/podiki/guix-pod/-/blob/main/taffybar.scm

Checking now taffybar does not build (some dependent package failing,

looks like needs an input change) but ghc-gi-gdk does. This should be

the bulk of the work you need beyond polishing (linting, license checks,

all that). It is a lot of packages, many are the autogenerated

haskell-gi packages as I'm sure you are familiar.

On the gobject-introspection front, I do remember needing some tinkering

there for cairo, and ended up using what was suggested here:

https://issues.guix.gnu.org/49122#4

I haven't used Taffybar much since I went back to my lisp land (StumpWM)

but hopefully this is helpful. Some Haskell experts can chime in with

other details or polishing once it builds.

Let me know if you need help parsing this early and rough packaging I

did, though I think it shouldn't take much to get it to build again

(famous last words, I know).

John

Hi John,

Thanks for taking the time to chime in, much appreciated!

I took a look at your repo and found that our definition of ghc-gi-gdk is almost exactly the same (sans some historical differences (eg, using gtk (v4) vs gtk+)).

Interesting! Sadly I rediscovered this and provided a very similar solution in the first message of this bug report (with the help of a similar issue in nix). imho we should adjust the goject-introspection package to include working cairo typelib files.

I'll take a closer look this evening whether or not there is some other difference that could be causing the reported build failure.

Definitely useful insight, thanks again John!

I don't foresee any issues with understanding whats going on (similarly, famous last works ?) but if I have any questions I'll let you know in this thread.

Further, when I enter a simulated build environment, the file does indeed exist.

The ENOFILE can happen while loading _any_ dependency of the required
lib, and will be propagated back.  Since the file seems to exist in the
development environment as you mentioned, my guess is that some
dependency somewhere seems to be missing somehow.  You could try
manually running the `./configure` script or equivalent that's failing,
with LD_DEBUG=libs set in the environment (or even =all), and seeing if
that error still happens/what the error is precisely.  If it doesn't
happen, this would be even more suspicious.

Best,
