Bug 504068 – dev-python/pygobject:3 should RDEPEND on x11-libs/cairo

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Arfrever Frehtes Taifersar Arahesis 2014-03-10 11:54:12 UTC]

dev-python/pygobject:3 currently has unconditional DEPEND="x11-libs/cairo[glib]" and no run-time dependency on x11-libs/cairo.

Based on my testing of all ebuilds, the correct dependencies should be:
  In =dev-python/pygobject-3.2*:
    DEPEND="cairo? ( x11-libs/cairo )"
    RDEPEND="cairo? ( x11-libs/cairo )"
  In >=dev-python/pygobject-3.4:
    DEPEND="cairo? ( x11-libs/cairo[glib] )"
    RDEPEND="cairo? ( x11-libs/cairo )"

I think the unconditionnal DEPEND is here for unittests. But maybe that constraint was removed by now ?

[Comment 2 Arfrever Frehtes Taifersar Arahesis 2014-03-11 01:36:34 UTC]

All ebuilds of dev-python/pygobject:3 already set REQUIRED_USE="test? ( cairo )".

pygobject-3.3.x and 3.4.0 had a hard build-time dependency on cairo, even if tests were disabled.

This was a mistake that upstream fixed in 3.4.1, but I forgot to update our ebuilds, sorry :/

(In reply to Alexandre Rostovtsev from comment #4)

It is incomplete.

1. Installed files are linked against libcairo.so.2 from x11-libs/cairo:
$ scanelf -qF "%F: %n" $(qlist dev-python/pygobject-3 | sort) | grep libcairo
/usr/lib64/python2.6/site-packages/gi/_gi_cairo.so: libglib-2.0.so.0,libcairo.so.2,libpthread.so.0,libc.so.6
/usr/lib64/python2.7/site-packages/gi/_gi_cairo.so: libglib-2.0.so.0,libcairo.so.2,libpthread.so.0,libc.so.6
/usr/lib64/python3.1/site-packages/gi/_gi_cairo.so: libglib-2.0.so.0,libcairo.so.2,libpthread.so.0,libc.so.6
/usr/lib64/python3.2/site-packages/gi/_gi_cairo.cpython-32.so: libglib-2.0.so.0,libcairo.so.2,libpthread.so.0,libc.so.6
/usr/lib64/python3.3/site-packages/gi/_gi_cairo.cpython-33.so: libglib-2.0.so.0,libcairo.so.2,libpthread.so.0,libc.so.6
/usr/lib64/python3.4/site-packages/gi/_gi_cairo.cpython-34.so: libglib-2.0.so.0,libcairo.so.2,libpthread.so.0,libc.so.6

2. libcairo-gobject.so.2 (provided by x11-libs/cairo[glib]) is used at build time even with USE="cairo -test".

Good point.
