Bug 432130 – x11-libs/libva-intel-driver-1.0.18-r1 fails to compile

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Karl Newman 2012-08-20 20:46:03 UTC]

Compilation fails with the following error (trimmed):

Possible mismatch with required x11-libs/libva version? (I have libva-1.1.0 installed which has subsequently been removed from the ebuilds.)

[Comment 1 Andreas Sturmlechner 2012-08-20 20:56:26 UTC]

... just why?

See this:

$ equery d libva
 * These packages depend on libva
...
x11-libs/libva-intel-driver-1.0.18-r1 (>=x11-libs/libva-1.0.16)

[Comment 2 Andreas Sturmlechner 2012-08-20 20:58:08 UTC]

Sorry, I forgot to mention that because of some upstream funnyness 1.0.16 is actually newer than 1.1.0.

[Comment 3 Karl Newman 2012-08-20 21:40:35 UTC]

Thanks, that fixed it. I emerged x11-libs/libva-1.0.16 and then x11-libs/libva-intel-driver-1.0.18-r1 emerged just fine.

I normally try to avoid downgrading (which this appeared to be) and I figured the libva-1.1.0 ebuild would be replaced or upgraded shortly following its removal, but I didn't know about the upstream version sillyness.

[Comment 4 Andreas Sturmlechner 2012-08-22 06:15:17 UTC]

I also do that sometimes, but an additional 'equery c <package>' doesn't hurt to gather some info about the nature of a mask/removal.

That's a completely awesome command. I've always hunted up the ChangeLog manually. I've been using Gentoo for 7 years and I'm still learning things... Thanks!
