- part A – compilation and libraries:
Intro: when we write a “normal” C application, we have all the source code files. We compile and link them to a single executable file.
We can also compile our code to a library that can be included to other projects statically or dynamically.
In this task you are requested to produce a simple C executable, and a shared library that can be used by this executable. You are also requested to provide a Make file, that will help to utilize each of the sub tasks.
Subtask 1 1.1 write a “hello Ariel” program,in a separate file named “hello_Ariel” file (c and h). 1.2 write a short main “main1_1” that will include “hello_Ariel”, and use it. 1.3 write a make file to compile the code.
Subtask 2 2.1 compile “hello_ariel” as a shared object (.so) library 2.2 write a short main “main1_2” that will use this library 2.3 compile to a single executable and update the make file
Subtask 3 3.1 write a short main “main1_3”, that will load the lib file from subtask 2 in runtime. 3.2 compile the main and alter the make file.
Subtask 4 4.1 practice with tools (which functions exist, which libs are used) 4.2 alter the make file to have default build, and clean options
- part B - Processes:
You are requested to implement a aunching app, that will start a few processes. Subtask 1 Start 2 processes as nested childs of the main app. Like this: App -> process1 -> process 2.
Subtask 2 Start 2 processes with the same shared memory (like threads). Like this: 3*App
Subtask 3 Start a daemon process
Subtask 4 Modify your app, to have all the above subtasks together. Show the relevant processes tree that will reflect the tasks result.
