Build Flow¶

Building and Deploying Python code with native shared libraries a continuously involving ordeal, hence I have provided the equivalent CMake/Makefile command in comments to be relatable to C++. Internally Cmake and Make are invoked. The build-flow currently uses setuptools, which is deprecated in Python 3.12.

Install Dependencies¶

See requirements.txt

Environment Variables¶

Variable	Default Value	Description
SKNRF_DIR	import site ; site.getsitepackages()[0]	Python SKNRF Module Directory
CONDA_PREFIX	/usr/local	C++ Sysroot
VISA_LIB	@py	Visa Library Location

Release Build¶

sudo python3 setup.py clean                              # sudo make clean
python3 setup.py config                                  # cmake ..
python3 setup.py build                                   # make
sudo python3 setup.py install                            # sudo make install

Example¶

python3 ${SKNRF_DIR}/sknrf/main.py

Tests¶

cd ${SKNRF_DIR}/sknrf ; nosetests --config=nose.cfg

Runtime Configuration¶

${SKNRF_DIR}/sknrf/sknrf.yml contains runtime configuration settings. Beware of Environment Variables set in this file.
