libharfbuzz-gobject is always built when glib is used for harfbuzz because the ebuild has the following line: $(use_with glib gobject) However, not everybody wants to have an extra library (libharfbuzz-gobject). e.g. CrOS does not. I think we can do the following: 1. Add gobject to IUSE 2. Add the following line REQUIRED_USE="gobject? ( glib )" 3. Replace the abouve 'use_with' line with $(use_with gobject) Reproducible: Always Steps to Reproduce: 1. Enable 'glib' in harfbuzz ebuild 2. 3. Actual Results: libharfbuzz-gobject.so is created Expected Results: There should be a way to build libharfbuzz with glib but without libharfbuzz-gobject created.
Glib will always come with gobject. Making it optional in harfbuzz does not make sense as it will not lighten downloads if you keep USE=glib and it will most likely not result in a big difference in build time either.
(In reply to Gilles Dartiguelongue from comment #1) we're not worried about build times. it installs extra files which are not used and we want to shrink down the installed footprint. would USE=introspection be more appropriate here ? no idea what harfbuzz-gobject is actually used for ...
(In reply to SpanKY from comment #2) > no idea what harfbuzz-gobject is actually used for ... Actually, that's a good question. After lots of grepping and ldd, as far as I can see, the *only* thing in my gnome-3.14 install that uses harfbuzz-gobject is harfbuzz's gobject-introspection bindings. I think we should make make harfbuzz-gobject optional, controlled either by USE=introspection or a new USE=gobject flag.
I would vote for "introspection" USE
