Installation of Tracker-miners

[Note]

Note

If you plan to run the tests, some timeouts are too short when using spinning disks. There are two places where timeouts are used: first, individual tests inside a group of tests have a default timeout of 10s. This can be changed by setting the environment variable TRACKER_TESTS_AWAIT_TIMEOUT to the desired value when running the tests (see below). Second, a global timeout for a group of tests is fixed at configuration time. The default value in the functional-tests directory (other directories have only short lived tests) may be increased with the following command (replace 200 with a value suitable for your machine):

sed -i s/120/200/ tests/functional-tests/meson.build

First, fix some crashes introduced by gstreamer-1.22.9:

sed -i '/ALLOW_RULE (shutdown);/a ALLOW_RULE (getsockopt);' src/libtracker-miners-common/tracker-seccomp.c

Install Tracker-miners by running the following commands:

mkdir build &&
cd    build &&

meson setup --prefix=/usr                 \
            --buildtype=release           \
            -Dsystemd_user_services=false \
            -Dman=false                   \
            ..                            &&
ninja

To test the results, issue (adjust the individual test timeout to a value suitable for your machine, see the note above):

dbus-run-session env TRACKER_TESTS_AWAIT_TIMEOUT=20 ninja test &&
rm -rf ~/tracker-tests
[Note]

Note

The tests create files in the user directory (up to 24 MB), so they have to be removed afterwards.

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.

-Dman=false: This switch prevents the build process from generating man pages. Omit this switch if you have asciidoc-10.2.0 installed and wish to generate and install the man pages.

-Dsystemd_user_services=false: This switch prevents the build process from installing systemd units since they are useless on SysV systems.

-Dseccomp=false: This option disables the seccomp system call filter. On some architectures, such as i686 and ARM, the functions that tracker-miners uses are not guarded properly, and tracker-miners will get killed with a SIGSYS as a result.

-Dminer_rss=false: Use this option if you have not installed the recommended dependency libgrss.

-Dbattery_detection=none: Use this option if you have not installed the recommended dependency upower. Do not use this option if your system has a battery (laptop battery or UPS), or tracker miners may waste the battery power and lifespan when the A/C power is unavailable.
