See demo.mov for example of how to run the application (instructions below).

The repository contains two applications:

• img_provider_cpp is a C++ application that reads images from the file and sends them to image processor over the shared memory.
• processor_rust is the image processor that processes the image and writes the result (most common colour) to the shared memory.

Pre-requisites (locations to download provided for mac OS)

1. Install clang if not already available (clang --version to check if available, if not use xcode-select --install on mac OS).
2. Install rust: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh. See https://www.rust-lang.org/tools/install.

To run:

1. Open two terminal windows, go to cd processor_rust in the first and cd img_provider_cpp in the second.
2. Build processor_rust from processor_rust terminal: cargo build.
3. Create build dir from img_provider_cpp: mkdir build.
4. Build img_provider_cpp from img_provider_cpp terminal: clang++ main.cc -o build/image_provider.out.
5. Run processor_rust from processor_rust terminal (it must be launched first as it initializes the shared memory): cargo run.
6. Run img_provider_cpp: ./build/image_provider.out.

Rust application uses libc external dependency that is downloaded when you build the project.
