Setup

1. Create CMakeLists.txt

touch CMakeLists.txt

Docker Setup and uses

1. Build and run the project in dev mode

docker compose up --build

This will pull & build images and create necessary network and volumes

2. Stop containers (if needed)

docker compose stop

The containers are set to restart automatically; stop them manually if not needed

3. Restart containers

docker compose start

Start project

docker compose exec dev bash -c "cmake -S . -B build && cmake --build build && ./build/hello"

replace ./build/hello to the name of your executable (cf CMakeLists.txt last line add_executable)

docker compose exec dev bash -c "rm -rf build/*"

Command to run inside container

1. Build with Ninja (if you installed it):

cmake -S . -B build        # configure build directory
cmake --build build       # compile the project
./build/hello             # run the resulting executable

2. Keep the container open after running a command:

make -C build

3. Clean ./build folder if needed

rm -rf build/*
