Olaf Hering 809b6ecb53 tools/thermal: tmon: use pkg-config also for CFLAGS
The header <panel.h> might be in /usr/include/ncursesw, which is not
part of the standard include path. This fixes compile on openSUSE.

Anand Moon b100e77f17 tools/thermal: tmon: fixed the 'make install' command
To install tmon we issue "make install" which produces bellow error.

root@odroidxu3:/usr/src/odroidxu3-4.y-testing/tools/thermal/tmon# make install
mkdir -p /usr/bin
install -m 755 -p "tmon" "/usr/bin/tmon"
mkdir -p /
install -m 644 -p "" "/"
install: cannot stat ‘’: No such file or directory
make: [install] Error 1 (ignored)

Brian Norris 96a0d99c72 tools/thermal: tmon: use pkg-config to determine library dependencies
Some distros (e.g., Arch Linux) don't package the tinfo library
separately from ncurses, so don't unconditionally include it. Instead,
use pkg-config.

The $(STATIC) ugliness is to handle the reported build case from commit
6b533269fb ("tools/thermal: tmon: fix compilation errors when building
statically"), where a developer wants to be able to build with:

  make LDFLAGS=-static

which requires an additional pkg-config flag.

Finally, support a lowest common denominator fallback (-lpanel
-lncurses) for build systems that don't have pkg-config entries for
ncurses.

Brian Norris 1b0eaa2cc2 tools/thermal: tmon: support cross-compiling
We might want to prepare CFLAGS outside of this Makefile, so don't
overwrite its initial value.

Then, support $(CROSS_COMPILE), so we can use a cross-compile toolchain.

Javi Merino 6b533269fb tools/thermal: tmon: fix compilation errors when building statically
tmon fails to build statically with the following error:

stdscr() and friends are in libtinfo (part of ncurses) so add it to
the libraries that are linked in when compiling tmon to fix it.

Jacob Pan 94f69966fa tools/thermal: Introduce tmon, a tool for thermal subsystem
Increasingly, Linux is running on thermally constrained devices. The simple
thermal relationship between processor and fan has become past for modern
computers.

As hardware vendors cope with the thermal constraints on their products,
more sensors are added, new cooling capabilities are introduced. The
complexity of the thermal relationship can grow exponentially among cooling
devices, zones, sensors, and trip points. They can also change dynamically.

To expose such relationship to the userspace, Linux generic thermal layer
introduced sysfs entry at /sys/class/thermal with a matrix of symbolic
links, trip point bindings, and device instances. To traverse such
matrix by hand is not a trivial task. Testing is also difficult in that
thermal conditions are often exception cases that hard to reach in
normal operations.

TMON is conceived as a tool to help visualize, tune, and test the
complex thermal subsystem.
