Hi maintainer,
*Please* consider getting rid of this Provides. It's been causing
sporadic build failures for 18 years! graphicsmagick forked from
imagemagick over 20 years ago and it's clear that they've diverged far
too much for graphicsmagick to be a drop-in replacement. (This shouldn't
even be a surprise, considering the time frame.)
Anyways, this Provides is causing icoextract builds in experimental to
fail[1]. I am not sure why this package got picked as a build-dep by the
buildd to begin with, but even when I remove a bunch of unsupported
convert flags, I am blocked because graphicsmagick does not support
creating .ICO files while imagemagick does[2]:
$ make testapp.ico
convert testapp.png -resize 16x16 tmp-testapp-16.bmp
convert testapp.png -resize 32x32 tmp-testapp-32.bmp
convert testapp.png -resize 48x48 tmp-testapp-48.bmp
convert testapp.png tmp-testapp*.bmp testapp.ico
convert: No encode delegate for this image format (ICO).
make: *** [Makefile:15: testapp.ico] Error 1
root@86890e20afd5:/tmp/src/tests# convert testapp.png testapp.ico
convert: No encode delegate for this image format (ICO).
Policy 7.5 suggests I can work around this with a versioned
dependency[3] on imagemagick, but I don't think I should need one to
begin with. When I build-dep on something I expect to get that, or
something that's actually compatible :/
