Bug 434540 – emerge output for binpkg useflag mismatch is not optimal

• Status: RESOLVED FIXED
• Product: Portage Development

[Description Patrick Lauer 2012-09-10 08:25:42 UTC]

# emerge -avg opencv --nodeps

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

[ebuild     U  ] media-libs/opencv-2.4.0 [2.3.1a-r1] USE="eigen examples ffmpeg gtk jpeg openexr opengl png qt4 tiff v4l -cuda -doc -gstreamer -ieee1394 (-ipp) -jpeg2k -pch% -python -tbb% -testprograms% -xine (-sse%*) (-sse2%*) (-sse3%) (-ssse3%)" 46,052 kB

Total: 1 package (1 upgrade), Size of downloads: 46,052 kB

!!! The following binary packages have been ignored due to non matching USE:

    =media-libs/opencv-2.4.0
        use flag(s): eigen, examples, ffmpeg, openexr, v4l


Problems:
- Not copy-paste'able for package.use (format is silly)
- It doesn't give any hints if these useflags need to be enabled or disabled for binpkg to match

This is fixed in git:

Example output:

    =media-libs/opencv-2.4.0 -eigen -examples -ffmpeg -openexr -v4l
