Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.

Package Information

At-Spi2 Core Dependencies

Required

dbus-1.14.10, GLib-2.82.4 (GObject Introspection required for GNOME), gsettings-desktop-schemas-47.1 (Runtime), and Xorg Libraries

Optional

Gi-DocGen-2024.1 and sphinx-8.1.3

Installation of At-Spi2 Core

Install At-Spi2 Core by running the following commands: 

mkdir build &&
cd    build &&

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

Now, as the root user: 

ninja install

The test suite requires the glib schemas of the package to be installed already. The tests also need to run in a graphical environment. Now that the package is installed, test the results by issuing: dbus-run-session ninja test.

Command Explanations

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