Reduce dependency on scrollkeeper (#743318)
Scrollkeeper and the associated OMF catalog files are used by the GNOME 2 version of yelp to display the GParted help manual. To see how this works try the following command: yelp ghelp:gparted GNOME version 3 and higher yelp do not require scrollkeeper or the OMF catalog files to properly display the GParted help manual. And in fact GNOME 3 deprecated the GNOME 2 method of building and installing GNOME help documents altogether; including use of GNOME_DOC_INIT autoconf macro, the gnome-doc-utils package and use of scrollkeeper. [GNOME 3] GNOME Goal: Port To New Documentation Infrastructure https://wiki.gnome.org/Initiatives/GnomeGoals/NewDocumentationInfrastructure Further, the next release of Debian, Debian 10 (Buster), will be removing the scrollkeeper / rarian package. rarian: Don't release with Buster https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=885657 GParted is still a GNOME 2 app using GNOME 2 documentation build system using autoconf GNOME_DOC_INIT macro. [GNOME 2] Migrating your documentation to gnome-doc-utils https://wiki.gnome.org/Projects/GnomeDocUtils/MigrationHowTo This is needed to build GParted documentation on still supported GNOME 2 distributions RHEL / CentOS 6. So avoid requiring deprecated scrollkeeper on GNOME 3 by automatically disabling scrollkeeper database updates when the scrollkeeper-update command is not available. Executable | Configure option used | Use scrollkeeper scrollkeeper-update | on command line | when building help exists? | | for GParted? --------------------+------------------------+------------------- Yes | <none> | Yes Yes | --enable-scrollkeeper | Yes Yes | --disable-scrollkeeper | No | | No | <any> | No Note that because GParted is still using the GNOME 2 documentation build system it still builds and installs OMF files. It is just that they are not required with GNOME 3 yelp and this commit automatically disables updating the scrollkeeper database when the scrollkeeper-update command is not available.
