Technical requirements

In order to let you try the programs immediately, we've set up a Docker image that has all the tools and libraries we'll need throughout the book. This is based on Ubuntu 19.04.

In order to set this up, follow these steps:

1. Download and install the Docker Engine from www.docker.com.
2. Pull the image from Docker Hub: docker pull kasperondocker/system_programming_cookbook:latest.
3. The image should now be available. Type in the following command to view the image: docker images.
4. You should have at least this image now: kasperondocker/system_programming_cookbook.
5. Run the Docker image with an interactive shell, with the help of the following command: docker run -it --cap-add sys_ptrace kasperondocker/system_programming_cookbook:latest /bin/bash.
6. The shell on the running container is now available. Run root@39a5a8934370/# cd /BOOK/ to get all the programs developed, by chapters.

The --cap-add sys_ptrace argument is needed to allow GDB in the Docker container to set breakpoints, which, by default, Docker does not allow.
