A sample project which creates a shared object (.so) library on linux using Rust programming language and calls it's function from another rust program.

Shared Object (.so) File :-

In simple words, a '.so' file on linux is what a 'dll' on windows.

It is a library that is linked to the executable but it is not embedded inside executable like static library (.a),so it will be loaded only when the executable is loaded.

For System Requirements please refer 'Application_Requirements.txt'

How to run the project.

1. Clone the repository.

2. Navigate inside project folder 'addition_library' from terminal.

3. Build this Library project using following command -
   cargo build

4. Navigate inside project folder 'addition_client' from terminal.

5. Build and run this binary project using following commands -

   cargo build

   cargo run

Application is tested on Ubuntu 20.04.5 LTS with WSL2 on Windows 10, working well.

Tested on Ubuntu 22.04.2 LTS using github actions, working well.

Output :-

1. Build Library project :
