Run Examples

We have provided a Makefile to facilitate running examples for the supported languages.

Before running the examples, please ensure that all dependencies are installed. Each language has its own dedicated README file located in its respective subdirectory. These README files contain detailed instructions for installing dependencies and running the examples. Alternatively, you can also simply execute make build for downloading, installing and building for all languages.

Note, these examples and commands were tested solely on Ubuntu 22.04 and may require tuning for other operating systems.
