attrs-25.4.0

Optional

libevdev-1.13.6, libxkbcommon-1.13.1, libxml2-2.15.1, munit, and structlog

Installation of libei

Install libei by running the following commands: 

mkdir build &&
cd    build &&

meson setup --prefix=/usr --buildtype=release -D tests=disabled &&
ninja

This package does come with a test suite, but it requires an external dependency. If you have both munit and structlog installed, and you wish to run the test suite, run the following commands: 

meson configure -D tests=enabled &&
ninja test

Now, as the root user: 

ninja install

Command Explanations

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

-D tests=disabled: This switch avoids a dependency on munit. Remove this switch if you have munit installed and wish to run the test suite.
