Pybind11 allows for Python embedding within C++ code (and creating C++ bindings for Python). NexRes relies on Pybind11 to call Python code from C++.
This code was tested on Ubuntu 20.04.4 LTS. Python 3.10.8 was installed using brew in the location /home/ubuntu/.linuxbrew/bin/python3. Using brew helps simplify the linking process during compilation. This location is referenced in nexres/.bazelrc
build --action_env=PYTHON_BIN_PATH="/home/ubuntu/.linuxbrew/bin/python3"
Make sure you have the python libraries installed. These are used when the binary is run.
sudo apt-get install python3.10-dev
Calls example Python code. Provides an example of reading in the file print_sample.py into a string and executing the string as Python code. Also provides an example of importing a Python module into C++ and calling one of its functions.
Make sure to execute the code from within this directory as when importing the “validator_example” module the code searches the same directory.
