Introduction to At-Spi2 Core

The At-Spi2 Core package contains a comprehensive accessibility framework for the Assistive Technologies available on the GNOME platform. This includes a set of interfaces which are implemented by other toolkits and applications.

This package is known to build and work properly using an LFS 12.1 platform.

Package Information

At-Spi2 Core Dependencies

Required

dbus-1.14.10, GLib-2.78.4, gsettings-desktop-schemas-45.0 (Runtime), and Xorg Libraries

Optional (Required if building GNOME)

gobject-introspection-1.78.1

Optional

Gi-DocGen-2023.3 and sphinx-7.2.6

Installation of At-Spi2 Core

Install At-Spi2 Core by running the following commands: 

mkdir build &&
cd    build &&

meson setup ..            \
      --prefix=/usr       \
      --buildtype=release \
      -Dsystemd_user_dir=/tmp &&
ninja

The test suite also requires the glib schemas of the package to be installed already. To test the results, install the package first, then issue: dbus-run-session ninja test. One test, atk-test, is known to timeout on some systems.

Now, as the root user: 

ninja install &&
rm /tmp/at-spi-dbus-bus.service

Command Explanations

--buildtype=release: Specify a buildtype suitable for stable releases of the package, as the default may produce unoptimized binaries.

-Dsystemd_user_dir=/tmp: This flag puts the systemd unit file in /tmp where it will be removed. SysV is unable to use this file.

-Ddocs=true: Use this switch if you want to build the documentation. Note that you must have both Gi-DocGen-2023.3 and sphinx-7.2.6 installed on your system.
