libevdev 1.13.4
Introduction to libevdev
The libevdev package contains
common functions for Xorg input drivers.
This package is known to build and work properly using an LFS
12.4 platform.
Package Information
libevdev Dependencies
Optional
Doxygen-1.14.0, Valgrind-3.25.1 (optional for tests), and
check (required for
tests)
Kernel
Configuration
Enable the following options in the kernel configuration and
recompile the kernel if necessary:
Device Drivers --->
Input device support --->
-*- Generic input layer (needed for keyboard, mouse, ...) [INPUT]
<*/M> Event interface [INPUT_EVDEV]
If you want to test this package with full coverage, the
following options are needed as well:
Device Drivers --->
Input device support --->
-*- Generic input layer (needed for keyboard, mouse, ...) [INPUT]
[*] Miscellaneous devices ---> [INPUT_MISC]
<*/M> User level driver support [INPUT_UINPUT]
If you build this as a module, it needs to be inserted before the
test suite runs.
Installation of libevdev
Install libevdev by running the
following commands:
mkdir build &&
cd build &&
meson setup .. \
--prefix=$XORG_PREFIX \
--buildtype=release \
-D documentation=disabled \
-D tests=disabled &&
ninja
The test suite requires Check
that we've removed from LFS.
Now, as the root user:
ninja install
Command Explanations
-D tests=disabled: This
allows the package to compile if Check is not installed. We've removed
Check from LFS.

contains a Generic Linux input driver for the Xorg X server. It
handles keyboard, mouse, touchpads and wacom devices, though for
touchpad and wacom advanced handling, additional drivers are
required.
This package is known to build and work properly using an LFS

libinput-1.29.0
Introduction to Libinput
libinput is a library that
handles input devices for display servers and other applications
that need to directly deal with input devices.
This package is known to build and work properly using an LFS
12.4 platform.
Package Information
libinput Dependencies
Required
libevdev-1.13.4 and mtdev-1.1.7
Optional
Valgrind-3.25.1 (to run the tests),
GTK-3.24.50 (to build the GUI event viewer),
libunwind-1.8.2 (required for tests),
libwacom-2.16.1, Doxygen-1.14.0, Graphviz-13.1.2, recommonmark-0.7.1, and sphinx_rtd_theme-3.0.2 (required to
build documentation), pyparsing-3.2.3 (for one non-root test),
pytest-8.4.1 (for another non-root
test), and check (for another
non-root test)
Kernel
Configuration for Running the Libinput Test Suite
Although libinput works with the same kernel configuration used
by libevdev-1.13.4, its standard and more
expansive test suite requires the presence of /dev/uinput (as well as both Valgrind-3.25.1 and libunwind-1.8.2).
If you wish to run the standard test suite, enable the following
option in the kernel configuration and recompile the kernel if
necessary:
Device Drivers --->
Input device support --->
-*- Generic input layer (needed for keyboard, mouse, ...) [INPUT]
[*] Miscellaneous devices ---> [INPUT_MISC]
<*/M> User level driver support [INPUT_UINPUT]
If you build this as a module, it needs to be inserted before the
test suite runs.
Installation of Libinput
Install libinput by running the
following commands:
mkdir build &&
cd build &&
meson setup .. \
--prefix=$XORG_PREFIX \
--buildtype=release \
-D debug-gui=false \
-D tests=false \
-D libwacom=false \
-D udev-dir=/usr/lib/udev &&
ninja
To test the package, issue: meson
configure -D tests=true && ninja test.
Many tests are skipped unless running the test suite as the
root user. To run those tests, as
the root user issue: meson test --suite=root.
Now, as the root user:
ninja install
If you have passed -D
documentation=true to meson, you can install the
generated documentation by running the following commands as the
root user:
install -v -dm755 /usr/share/doc/libinput-1.29.0/html &&
cp -rv Documentation/* /usr/share/doc/libinput-1.29.0/html
Command Explanations
--buildtype=release:
Specify a buildtype suitable for stable releases of the package,
as the default may produce unoptimized binaries.
-D debug-gui=false: This
switch disables creation of a visual debug helper for libinput.
Remove if you want it, and you have GTK-3.24.50 installed.
-D tests=false: This
switch disables compilation of the standard test suite. Even with
the tests defined as false, you can still run the first six minor
tests as a regular user, but one will be skipped if pyparsing-3.2.3 is not installed, and
another one if pytest-8.4.1 is not installed.
-D libwacom=false: Remove
this option if you have libwacom-2.16.1 installed, or if you are
installing GNOME.
-D
udev-dir=/usr/lib/udev: In case that the value of
XORG_PREFIX is not set to /usr, this option prevents the package from
installing Udev rules and helpers into $XORG_PREFIX/lib/udev which is not searched by
Udev daemon. This option is not needed for systems with
XORG_PREFIX set to /usr, but does no harm.
-D documentation=true: This switch
enables generation of the documentation. Add it if you want to
generate the documentation. See the optional dependencies
required to build documentation.
