The goals of this project are:

Specific steps

Prepare an Ubuntu development image

  1. Install Virtual Box.
  2. Download ubuntu-16.04.6-server-i386.iso, the ISO (image of a CD or DVD) for ubuntu 16.04.6 server version, 32-bit (i386).
  3. Install the ISO on a Virtual Box virtual machine.
    1. Start Virtual Box, select New, and fill out the panel with any name, Linux, Ubuntu 32. (not really important)
    2. On the next several panels, select: 2G RAM; create virtual hard disk; VDI; dynamic; and 32G.
    3. You will be returned to the main panel, with the new image "Powered Off". Start it with the green arrow.
    4. You are prompted for the ISO image. Use the folder icon (small and to the right of the pull down) to navigate to your image, select and start.
    5. The purple screens are the Ubuntu installer. Take defaults. Use the TAB if the mouse does not yet work.
    6. Choose a machine name and a username.
    7. You will need to TAB (or mouse) choose YES to write the partition and format the filesystem. No proxy.
    8. Add Open SSH Server to the packages to install. Yes to install GRUB.
    9. Reboot and log in.
  4. Log into virtual ubuntu image (terminal) and update all software then install needed packages: sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get install subversion
    sudo apt-get install build-essential
    reboot
Special notes:

Discussion

The provided helloworld.c is the template. Please modify to satisfy the test case. The Makefile provided has the default target to build the binary. The test target redirects output to the helloworld.out file and then compares the captured output to the reference output give in helloworld.ref. Differences will be reported. If the match, the diff program is silent.

The clean target removes build and test products. Never commit products! Commit only sources (in this project — Makefile, helloworld.c and helloworld.ref). Points off for committing build products.
