Description Morgan Wesström 2008-10-22 23:18:10 UTC

media-libs/urt-3.1b-r1 with USE="gif" depends on media-libs/giflib.
media-libs/giflib-4.1.6-r1 with USE="rle" depends on media-libs/urt.
Creates a circular dependency while emerging media-video/vlc with both USE flags set.

Reproducible: Always

Steps to Reproduce:
1. Unmerge media-libs/giflib and/or media-libs/urt if they're installed. 
2. Set USE-flags gif and rle in /etc/make.conf
3. emerge vlc

Actual Results:  
Emerge stops with an error about circular dependency between media-libs/giflib and media-libs/urt.

Expected Results:  
Clean install of media-video/vlc.

Workaround is to first emerge -1 --nodeps giflib. Then it's possible to emerge vlc.

Comment 1 Morgan Wesström 2008-10-22 23:53:54 UTC

Some additional info and clarifications:
The libraries depend on each other to build (DEPEND).

Vlc triggers this because it depends on ffmpeg and ffmpeg with USE="imlib" depends on imlib2 and imlib2 with USE="gif" depends on giflib.

duplicate of bug #175808

To fix your problem, emerge the two ebuilds seperatly with a few flags turned OFF, then turn them on. Emerge -va1 foo, will help NOT inserting the ebuild in world (usefull if you want to avoid having simple deps in your world).

Please, close your bug.
