requirements------------
* If you are building completely from upstream; please install libcpupower byrunning `make install-lib` within the cpupower directory. This installs thelibcpupower.so file and symlinks needed. Otherwise, please make sure a symlinkto libcpupower.so exists in your library path from your distribution'spackages.* The SWIG program must be installed.* The Python's development libraries must be installed.
Please check that your version of SWIG is compatible with the version of Pythoninstalled on your machine by checking the SWIG changelog on their website.https://swig.org/
Note that while SWIG itself is GPL v3+ licensed; the resulting output,the bindings code: is permissively licensed + the license of libcpupower'slibrary files. For these bindings that means GPL v2.
Please see https://swig.org/legal.html and the discussion [1] for more details.

build-----
Install SWIG and the Python development files provided by your distribution.
Build the object files for libcpupower by running make in the cpupowerdirectory.
Return to the directory this README is in to run:
$ make
testing-------
Please verify the _raw_pylibcpupower.so and raw_pylibcpupower.py files havebeen created.
To run the test script:
$ python test_raw_pylibcpupower.py
developing/using the bindings directly--------------------------------------
You need to add the Python bindings directory to your $PYTHONPATH.
You would set the path in the Bash terminal or in the Bash profile:
PYTHONPATH=~/linux/tools/power/cpupower/bindings/python:$PYTHONPATH
This allows you to set a specific repo of the bindings to use.
installing/uninstalling-----------------------
Python uses a system specific site-packages folder to look up modules to importby default. You do not need to install cpupower to use the SWIG bindings.
You can install and uninstall the bindings to the site-packages with:
sudo make install
sudo make uninstall
