• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Kostadin Shishmanov 2022-12-07 19:40:17 UTC]

media-libs/fdk-aac is ignoring -Werror=odr in both CFLAGS and LDFLAGS during the linking phase

[Comment 1 Kostadin Shishmanov 2022-12-07 19:40:38 UTC]

Created attachment 840829 [details, diff]
patch from irc

[Comment 2 Sam James 2022-12-07 19:48:44 UTC]

We'll need to both patch sys-devel/libtool (and send it upstream, although our other patches are still pending) and then add it into elt-patches.
