Subject: [bug#49227] [PATCH 1/3] build: qt-build-system: Allow users to override/extend XDG_DATA_DIRS.
Date: Fri, 25 Jun 2021 14:08:21 -0400	[thread overview]
Message-ID: <20210625180823.10382-1-maxim.cournoyer@gmail.com> (raw)
In-Reply-To: <20210625180414.10045-1-maxim.cournoyer@gmail.com>

Before this change, XDG_DATA_DIRS was wrapped using '=, which meant that it
wouldn't pick up extra icons from the user's profile, for example.  When
enabling gtk+ theming support in qtbase, that led to crashes due to GTK not
finding icons from even the hicolor icon theme fallback (which is assumed to
exist).

* guix/build/qt-build-system.scm (variables-for-wrapping): Specify an extra
'wrap-type' information per variable that gets passed to the wrap-program
procedure.  Set the XDG_DATA_DIRS variable wrapping type to 'suffix', which
allows the user to both extend and override its value.
