The UPower package provides an interface for enumerating power devices, listening to device events, and querying history and statistics. Any application or service on the system can access the org.freedesktop.UPower service via the system message bus.

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.

Enable the following options in the kernel configuration and recompile the kernel if necessary:
General setup ---> -*- Namespaces support ---> [NAMESPACES] [*] User namespace [USER_NS]
Install UPower by running the following commands:
mkdir build &&
cd build &&
meson setup .. \
--prefix=/usr \
--buildtype=release \
-D gtk-doc=false \
-D man=false &&
ninja
To test the results, issue: LC_ALL=C
ninja test. The test suite should be run from a
local GUI session started with dbus-launch. On 32-bit machines, one
test will fail due to rounding errors: Tests.test_battery_energy_charge_mixed. On some
systems, two tests relating to the headphone hotplug feature are
known to fail. Those can be safely ignored since the functionality
still works.
Now, as the root user:
ninja install
-D gtk-doc=false: Prevents
building the documentation. Remove this if you have GTK-Doc installed and wish to build the
documentation.
-D man=false: Prevents
building the manual pages. Remove this if you have libxslt-1.1.43 and
docbook-xsl-nons-1.79.2 installed and
wish to build the manual pages.
