And I still reject this as being an inappropriate workaround: you shouldn’t have to use update-alternatives to build something unless desperately needed.

Following the search you provided we come across https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/323 for the general issue and the accepted MR https://gitlab.gnome.org/GNOME/gobject-introspection/-/merge_requests/63 that was filed by Kang Kai from Wind River.

This is not the solution.  Putting the .gir into $libdir is the answer.  See, for example, the Debian G-I policy: https://salsa.debian.org/gnome-team/gobject-introspection/-/blob/debian/latest/debian/policy.txt?ref_type=heads.

The interesting question is why Debian doesn’t feel the need to do this.

Yesterday, I spent several hours trying to install GIR files into libdir instead of datadir. However, it seems this is not a straightforward task.

I sought help from the GStreamer community here:
https://gitlab.freedesktop.org/gstreamer/gstreamer/-/issues/4383

According to the owner's response:
"This is not going to work as gobject-introspection (and meson) expect it to be installed in /usr/share. This has to be fixed in gobject-introspection first."

I realize this isn’t something that I can easily accomplish, sorry.

Also what exact configuration are you replicating this in, and what is the surrounding type that contains the differing size?  I can’t replicate with qemux86 vs qemux86-64:

$ ls core2-*/gstreamer1.0/*/image/usr/share/gir-1.0/Gst-1.0.gir
core2-32-poky-linux/gstreamer1.0/1.24.12/image/usr/share/gir-1.0/Gst-1.0.gir
core2-64-poky-linux/gstreamer1.0/1.24.12/image/usr/share/gir-1.0/Gst-1.0.gir

$ diff core2-*/gstreamer1.0/*/image/usr/share/gir-1.0/Gst-1.0.gir
$

I will work on this patch on behalf of my colleague from now

reproduce steps:
1. Add in local.conf the following lines:

  MACHINE ?= "qemux86-64"

  require conf/multilib.conf

  MULTILIBS ?= "multilib:lib32"

  DEFAULTTUNE:virtclass-multilib-lib32 ?= "core2-32"

2. add lib32-gstreamer1.0-dev gstreamer1.0-dev to core-image-minimal.bb

  IMAGE_INSTALL = "packagegroup-core-boot ${CORE_IMAGE_EXTRA_INSTALL} lib32-gstreamer1.0-dev gstreamer1.0-dev "

3. $ bitbake core-image-minimal

Missing space on the beginning of the string, it should be:
MULTILIB_SCRIPTS:append = " ${PN}-dev:${datadir}/gir-1.0/Gst-1.0.gir"
