Description Alexandre Rostovtsev (RETIRED) gentoo-dev 2014-05-04 05:54:24 UTC 
When trying to build uevt-2.3-r1 with vala-0.24:

/usr/bin/valac-0.24 --vapidir=../vapi --basedir=.. --pkg=libnotify --pkg gio-2.0 --pkg gtk+-2.0 --pkg vsystem --pkg configh  -C uevt.vala uevt-udisks.vala uevt-upower.vala udisks-interfaces.vala upower-interfaces.vala logger.vala config.vala utils.vala uevt-notify.vala disks-systray.vala power-systray.vala cpu-systray.vala configurator.vala power-infos.vala uevt-backlight.vala
uevt-notify.vala:54.9-54.20: error: `Notification' is an ambiguous reference between `GLib.Notification' and `Notify.Notification'
        Notification notif = new Notification(head, Markup.escape_text(body), icon);
        ^^^^^^^^^^^^
Compilation failed: 1 error(s), 0 warning(s)


I've worked around this by adding VALA_MAX_API_VERSION to the uevt ebuild (as a prerequisite for updating vala.eclass for 0.24). However, since uevt's upstream seems inactive and there is no fix in their git repository, you may want to apply a patch since old vala versions might go away at some point.

The fix should be similar to http://cgit.freedesktop.org/systemd/systemd-ui/commit/?id=282a352dff49c13e185d826af2a248b55988bc32

That helped.

Fixed in Portage and unrestricted the vala dependency again.
