It doesn't seem that x11-libs/gdk-pixbuf USE=X does anything other than provide the gdk-pixbuf-xlib-2.0.pc package and the related library out of gdk-pixbuf source trees contrib/ directory. However various packages, including gtk+:2 and gtk+:3 USE depend on it. But I don't see usage of that library anywhere - which makes sense, because it's a library for usage by pure xlib applications for image decoding and such. I think we should: * Try to see that there are no missing gdk-pixbuf X USE deps on packages that actually need gdk-pixbuf-xlib * Remove IUSE default from gdk-pixbuf * Remove wrong gdk-pixbuf[X] dependencies from many other packages than gtk+ (I found libreoffice from what I have installed, and it doesn't seem to link to it at least) - many of them are probably just historical from gdk-pixbuf having been inside gtk+ before, and it being a gtk+[X] before for obvious reasons. * Remove technically wrong gdk-pixbuf[X] dependency on the gtk+ SLOT if my claims are correct; this assumes point 1 is somewhat well done, as some consumers of gdk-pixbuf-xlib might have depended on it indirectly with gtk+[X] Comments, acks?

Ack. I should be easy to do, maybe Tranquillity could have a look at it.
Information for depend bugs to help figure out if it's really needed dep or not: gdk-pixbuf USE=X builds the extra library libgdk_pixbuf_xlib-2.0.so.0 and provides the gdk-pixbuf-xlib-2.0.pc pkg-config package. The extra library defines the following public functions: gdk_pixbuf_xlib_get_from_drawable gdk_pixbuf_xlib_init gdk_pixbuf_xlib_init_with_depth gdk_pixbuf_xlib_render_pixmap_and_mask gdk_pixbuf_xlib_render_threshold_alpha gdk_pixbuf_xlib_render_to_drawable gdk_pixbuf_xlib_render_to_drawable_alpha xlib_draw_gray_image xlib_draw_indexed_image xlib_draw_rgb_32_image xlib_draw_rgb_image xlib_draw_rgb_image_dithalign xlib_rgb_cmap_free xlib_rgb_cmap_new xlib_rgb_ditherable xlib_rgb_gc_set_background xlib_rgb_gc_set_foreground xlib_rgb_get_cmap xlib_rgb_get_depth xlib_rgb_get_display xlib_rgb_get_screen xlib_rgb_get_visual xlib_rgb_get_visual_info xlib_rgb_init xlib_rgb_init_with_depth xlib_rgb_set_install xlib_rgb_set_min_colors xlib_rgb_set_verbose xlib_rgb_xpixel_from_rgb
I've removed gdk-pixbuf[X] depend from gtk+:2 and gtk+:3 latest ~arch revisions after reviewing all the gtk+[X] using packages in main tree to not be using any gdk_pixbuf_xlib stuff. I have not reviewed (besides the filed w3m bug that just happened to show up as a preserved-lib) any of the gdk-pixbuf dependencies, if they have an unnecessary USE=X depend or are missing it, so this bug itself as a tracker and that reviewing work remains open - we just never had a gtk+ bug on the subject matter that blocks this tracker.
The xlib bits are now in an archived repository: https://gitlab.gnome.org/Archive/gdk-pixbuf-xlib
(In reply to Matt Turner from comment #5) > The xlib bits are now in an archived repository: > https://gitlab.gnome.org/Archive/gdk-pixbuf-xlib My expectation is that some of the dependencies on gdk-pixbuf[X] are unnecessary, and some are clearly still correct and needed. We should fix the incorrect dependencies and then probably package gdk-pixbuf-xlib separately for the real consumers.
