Mike Fleetwood	ddd32e838c	Migrate build from intltool to gettext translation (!107) ... [0] GNOME Goal: Gettext Migration https://wiki.gnome.org/Initiatives/GnomeGoals/GettextMigration This goal from 2016 is to migrate away from using intltool to help translate especially GNOME application related files, and instead use gettext directly now that gettext can handle a lot more file formats [1][2][3]. The GNOME Goal: Gettext Migration [0] says: "With gettext 0.19.8, there is really no need anymore to use intltool or GLib's dated gettext glue (AM_GLIB_GNU_GETTEXT and glib-gettextize)." This version or later of gettext is available in the oldest supported distributions except for SLES 12: Distribution EOL gettext -V Debian 10 2022-Aug 0.19.8.1 RHEL / CentOS 7 2024-Jun 0.19.8.1 Ubuntu 18.04 LTS 2023-Apr 0.19.8.1 SLES 12 SP5 2024-Oct 0.19.2 [4][5] As SLES 12 SP5 doesn't contain GParted and SLES 15 contains GParted 0.31.0 [6] loosing the ability to compile future GParted 1.5 release on SLES 12 SP5 is acceptable. Additionally the use of intltool and the associated GLib provided macro AM_GLIB_GNU_GETTEXT was the source of the remaining warnings from autoconf 2.71 seen in Fedora 36 and Ubuntu 22.04 LTS about the use of obsolete macros: $ ./autogen.sh ... autoreconf: running: /usr/bin/autoconf --force configure.ac:59: warning: The macro `GLIB_GNU_GETTEXT' is obsolete. configure.ac:59: You should run autoupdate. aclocal.m4:426: GLIB_GNU_GETTEXT is expanded from... >> aclocal.m4:526: AM_GLIB_GNU_GETTEXT is expanded from... >> configure.ac:59: the top level configure.ac:59: warning: The macro `AC_TRY_LINK' is obsolete. configure.ac:59: You should run autoupdate. ./lib/autoconf/general.m4:2920: AC_TRY_LINK is expanded from... lib/m4sugar/m4sh.m4:692: _AS_IF_ELSE is expanded from... lib/m4sugar/m4sh.m4:699: AS_IF is expanded from... ./lib/autoconf/general.m4:2249: AC_CACHE_VAL is expanded from... ./lib/autoconf/general.m4:2270: AC_CACHE_CHECK is expanded from... aclocal.m4:111: GLIB_LC_MESSAGES is expanded from... aclocal.m4:426: GLIB_GNU_GETTEXT is expanded from... >> aclocal.m4:526: AM_GLIB_GNU_GETTEXT is expanded from... >> configure.ac:59: the top level configure.ac:59: warning: The macro `AC_TRY_LINK' is obsolete. configure.ac:59: You should run autoupdate. ... Note that use of AM_GLIB_GNU_GETTEXT was deprecated in GLib 2.47.5 released 2016-01-18 [7]. Newer versions of GLib are included in the oldest supported distributions: Distro Package containing Version glib-gettext.m4 Debian 10 libglib2.0-dev-bin 2.58.3 RHEL / CentOS 7 glib2-devel 2.56.1 Ubuntu 18.04 LTS libglib2.0-dev-bin 2.56.4 SLES 12 SP5 glib2-devel 2.48.2 Therefore perform the migration described in the GNOME wiki documents [0][1]. This involves: 1. Replacing the macros used in configure.ac; 2. Copying Makevars.template to po/Makevars and setting PO_DEPENDS_ON_POT and DIST_DEPENDS_ON_UPDATE_PO to "no"; 3. Replace @INTLTOOL_*@ macros in Makefile.am with rules to use gettext to directly translate the relevent GNOME application files; 4. Removing (_) underscore marking translation prefixes from XML tags in GNOME application files as gettext understands which tags of which files need translating. For reference are these commits in projects GNOME-System-Monitor [8], Reversi [9] and Evince [10] making the same transition. At this point "./autogen.sh && make" succeeds, at least on Ubuntu which provides the instructions gettext needs to correctly translate .policy files by default. These: /usr/share/gettext/its/polkit.its /usr/share/gettext/its/polkit.loc are included in the base policykit-1 package.
