Bug 193335 – media-sound/alsa-utils-1.0.14 w/ USE=midi needs alsa-lib w/ USE=midi

• Product: Portage Development
• Status: RESOLVED DUPLICATE

[Description Mark 2007-09-21 15:44:14 UTC]

Just recently during a kdelibs (see bug #188151) I found I needed to enable midi. I had built my alsa packages without it.

So I edited /etc/portage/package.use and added two lines for the alsa packages that were installed:
media-libs/alsa-lib midi
media-sound/alsa-utils midi

The did:
# emerge --newuse world

These are the packages that would be merged, in order:

As you can see it's a real awkward dependency, it needs alsa-lib to be re-merged with the new flag first and then alsa-utils after.

I have made this as an enhancement rather than a bug because I'm not sure how portage should respond to this.

Reproducible: Didn't try

Steps to Reproduce:
1. Emerge alsa without midi support
2. Add midi flag to alsa
3. Re-emerge alsa

Actual Results:  
Fails to emerge alsa

Expected Results:  
Expected alsa to install

Obviously this was easy to work around, I just needed to re-merge alsa-lib on its own and then continue with the rebuild.

Yeah, re-emerge alsa-lib w/ USE=midi. What's exactly your request/defect here? No, portage won't do it for you.
