README.md

If you don't want/can't install VMWare Player & just want to GCC with Docker.

Install Docker

• Install Docker by grabbing it from the official site. Pick your OS:
  • For Linux, follow this guide
  • For macOS, see this guide
  • For Windows (g-d forbid), see this guide
• Make sure docker compose is installed too. It comes with Docker Desktop on Windows/macOS. On Linux, if it’s missing, get it from here.

Start the Container

• Clone this repo
• Put your C files in the internal folder in the repo.
• (Optional): Alter the .env file in the repo’s root directory with:

  USERNAME=your_username
  PASSWORD=your_password

• Open a terminal in the repo directory and run:

docker compose up -d

This starts the container in the background.

Get Inside

• To work in the container, run:

docker exec -it openu bash

• Now you’re in! Use the terminal like normal—your files from internal are at /root.

Uni wants us to compile using -ansi -pedantic -Wall flags, e.g:

gcc -g -ansi -pedantic -Wall test.c -o test

Notes

• The container’s named openu and uses GCC an older version (5.4) that the Uni uses by default. You can change that in the Dockerfile. If you do decide to use an older version though - Note that installing packages through apt might not work (old repo URLs), so make sure the RUN directive for installing is commented.
• Your internal/${USERNAME} folder maps to /home/${USERNAME} inside the container.
• Timezone’s set to Jerusalem.
• Check gcc --version inside to confirm it’s the version you want.
• If you mess up, check the Docker docs/just rebuild the container with

docker compose up --build --force-recreate -d

• To stop & remove the container, use

docker compose down

(I'd recommend you check out Docker/Podman if you're unfamiliar with it)

Thanks to KfearO for pointing out Ubuntu/dev env versioning!
