Comment # 3 on bug 1205043 from Stefan Hundhammer

BTW your dependency problems list already contains one possible route to go:
Downgrade all those libboost packages from the newer version 75_0 (which does
not come with Leap 15.4) to version 66_0 (which is the Leap 15.4 default).

But probably you installed that newer libboost for a reason. Now you have to
make a decision WHAT you want to break: That other project that you installed
libboost 75_0 for, or all those Leap 15.4 packages.

I found it a lot less headaches to keep the working machine (my desktop) and my
development system (where I build software) apart. If you don't, sooner or
later you will break compatibility between them, and you end up with a
half-broken system.

That used to be the inevitable fate of a software developer, but in this day
and age, virtual machines or containers (docker etc.) come to the rescue.
