Description Constantine Kardaris 2009-04-20 09:29:35 UTC

Seems like emerge -DNu silently drops packages with changed use flags when other packages depend on even a single of those use flags.

There shouldn't be a blockage warning msg instead?

thnx

We'll need a specific example. What you're describing doesn't sound possible. Maybe you've mistaken some other cause for this "silent dropping" thing that you describe.

I see, the problem is only triggered when you have an installed package which satisfies the USE dependency that would not be satisfied if the same package were rebuilt.

Sorry not sure I understand.  I'm seeing the same problem with:

media-video/mplayer -jack

Doesn't show up in emerge -DN world.  What dependency won't be satisfied if mplayer is rebuilt without jack?

If the package which requires it is already installed, this should show it as and unsatisfied dependency:

  emerge -p --complete-graph media-video/mplayer

If the package which requires it is not installed yet, then it's harder to find. One way to find it would be to uninstall the existing mplayer package and then run emerge -DNu world.

I did all that but I still don't see any dependencies?  See attached...

It seems like you have a different problem. Maybe you just need to add it to your world file:

  emerge --noreplace mplayer

That must have been it.  Thanks.
