In trying to emerge graphicsmagick, I am running into a confusing condition with its USE flags. It requires imagemagick which seems to ultimately cause emerge to block because imagemagick is already installed! If I emerge imagemagick and then change the USE flag on graphicsmagick to not require imagemagick, it works correctly.

The solution seems to me to be counterintuitive and makes me wonder whether there is something wrong with the USE logic in portage.

Code:

bopper jc # emerge imagemagick -pv

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

Calculating dependencies... done!
[ebuild   R   ] media-gfx/imagemagick-6.6.5.6  USE="X bzip2 corefonts cxx fontconfig graphviz jbig jpeg jpeg2k lcms openmp perl png raw svg tiff truetype wmf xml zlib -autotrace -djvu -fftw -fpx -gs -hdri -lqr -openexr -q32 -q8 -static-libs" VIDEO_CARDS="nvidia" 0 kB

When I try to emerge graphicsmagick, I get the following:
Code:

bopper jc # emerge graphicsmagick -pv

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

If I remove the USE flag for imagemagick from graphicsmagick, all seems to be well.

Code:

bopper portage # emerge graphicsmagick -p

imagemagick flag for graphicsmagick means:
Code:
--enable-magick-compat
     Normally GraphicsMagick installs only the 'gm' utility from which all commands may be accessed. Existing packages may be designed to invoke ImageMagick utilities (e.g. "convert"). Specify this option to install ImageMagick utility compatibility links to allow GraphicsMagick to substitute directly for ImageMagick. Take care when selecting this option since if there is an existing ImageMagick installation installed in the same directory, its utilities will be replaced when GraphicsMagick is installed.

So you can have both with this flag enabled.

Isn't it opposite ? To have both imagemagick and graphicsmagic installed, one should not use imagemagick option in graphicsmagick

There was clearly a reason that the imagemagick USE option wound up in make.conf, but it escapes me now. I doubt I would have included either if they hadn't been required for other applications.

I guess the authors of the imagemagick and graphicsmagick would care whether their package was providing a service if they replace each other. But as long as each works, I can't see that I care very much.

On the other hand, the USE flag that is required for some other application making imagemagick poisonous to graphicsmagick makes no sense and only causes trouble.

That is what package.use file is for, make.conf is for global USE flags, if you want to install some program alternative that can act and can install same binary files/links as original then you don't set that flag global.

The real cause for the problem seems to be a long list of bugs in bugzilla which are open but unresolved for months (I don't know why): All packages should actually depend on
Code:
|| ( media-gfx/imagemagick media-gfx/graphicsmagick[imagemagick] )
since media-gfx/graphicsmagick[imagemagick] should be a full replacements for imagemagick. So actually, with USE=imagemagick you should be able to uninstall imagemagick and install only graphicsmagick. For the moment, I suggest that you remove imagemagick, emerge graphicsmagick and put media-gfx/imagemagick-6.6.5.6 in your /etc/portage/profile/package.provided. This is a hack of course, but the only reasonable solution if you do not want to install two almost identical packages.

The moment seems to be still lasting...

Is there a ticket in bugzilla about that?
