EXTERNAL LIBRARIES
While htop depends on most of the libraries it uses at build time
there are two noteworthy exceptions to this rule. These
exceptions both relate to data displayed in meters displayed in
the header of htop and were intentionally created as optional
runtime dependencies instead. These exceptions are described
below:
libsystemd
The bindings for libsystemd are used in the SystemD meter
to determine the number of active services and the overall
system state. Looking for the functions to determine these
information at runtime allows for builds to support these
meters without forcing the package manager to install
these libraries on systems that otherwise don't use
systemd.
Summary: no build time dependency, optional runtime
dependency on libsystemd via dynamic loading, with
systemctl(1) fallback.
libsensors
The bindings for libsensors are used for the CPU
temperature readings in the CPU usage meters if displaying
the temperature is enabled through the setup screen. In
order for htop to show these temperatures correctly
though, a proper configuration of libsensors through its
usual configuration files is assumed and that all CPU
cores correspond to temperature sensors from the coretemp
driver with core 0 corresponding to a sensor labelled
"Core 0". The package temperature may be given as "Package
id 0". If missing it is inferred as the maximum value from
the available per-core readings.
Summary: build time dependency on libsensors(3) C header
files, optional runtime dependency on libsensors(3) via
dynamic loading.
