Bug 835698 – gnome-base/gnome-control-center-41.4 can't build with gnome-bluetooth-42.0, which is req'd by gnome-shell-42.0

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Jay Faulkner 2022-03-20 22:38:50 UTC]

I went to update my system today, and went through a troubleshooting journey:

- gnome-shell-42.0 would not build against stable gnome-bluetooth-3.34.5, so I ~amd64 keyword gnome-bluetooth, install it, and the new gnome-shell
- Now, with world fully updated (emerge -uUD @world does nothing), I get messages about preserved libraries -- the gnome-bluetooth libraries used by gnome-control-center, so I `emerge @preserved-rebuild` and discover the bug reflected in the summary: gnome-control-center-41.4, the latest one in the gentoo repo, will not build with the newer gnome-bluetooth.

So users are stuck, workarounds are:
- mask gnome-shell 42.0
or 
- leave the preserved libraries for gnome-control-center

Reproducible: Always

Steps to Reproduce:
1. Install latest unstable gnome-shell and gnome-bluetooth
2. Attempt to rebuild latest unstable gnome-control-center
Actual Results:  
Run-time dependency gnome-bluetooth-1.0 found: NO (tried pkgconfig and cmake)

meson.build:251:2: ERROR: Dependency "gnome-bluetooth-1.0" not found, tried pkgconfig and cmake



Expected Results:  
A successful build.

A similar error occurred with stable gnome-bluetooth (which gnome-control-center builds successfully against) when building gnome-shell-42.0 -- except it couldn't find `gnome-bluetooth-3.0`. Installing gnome-bluetooth-42.0 package resolved this issue.
