Installation of At-Spi2 Core

Install At-Spi2 Core by running the following commands:

mkdir build &&

A session bus address, normally available in an Xorg terminal, is necessary to run the tests. 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: ninja test.

Now, as the root user:

ninja install
