Enable the following options in the kernel configuration and recompile the kernel if necessary:
General Setup --->
[*] Namespaces support ---> [CONFIG_NAMESPACES]
[*] User namespace [CONFIG_USER_NS]First, remove an unneeded dependency from a test:
sed '/parse_version/d' -i src/linux/integration-test.py
Install UPower by running the following commands:
mkdir build &&
cd build &&
meson --prefix=/usr \
--buildtype=release \
-Dgtk-doc=false \
-Dman=false \
.. &&
ninja
To test the results, issue: LC_ALL=C ninja test. Some checks may not pass due to missing files. Test suite should be run from a local GUI session started with dbus-launch.
Now, as the root user:
ninja install
