Exercise: Build Multiple Packages Using Separate Install Targets

Task

In this exercise, you are required to create multiple binary packages (calculate-average and calculate-average-data) from one source package (calculate-average) using separate install targets.

• You are given a scores file with the content consisting of numbers on each line.

• You are also given a calculate-average.c file, which reads the numbers from the scores file and calculates their average. If the scores file is empty, it prints a message informing the user of that and displays the message No file found if no such file exists.

To complete the task, you need to perform the following steps:

1. In the Makefile, add statements to install the files calculate-average and scores separately to the location where they are expected to be found by dh_builddeb.

2. Make the necessary changes, if any in the control and rules files of the calculate-average/debian directory to build the packages calculate-average and calculate-average-data.

3. In the debian/rules file, override the dh_auto_install step to call make install_binary and make install_data with the appropriate install targets and the locations where the files can be found by dh_builddeb.

After these file modifications, perform the following steps:

1. Build and install the calculate-average-data package and then the calculate-average package.

2. If your package is built successfully, typing calculate-average will display an average of the scores present in the file scores.
