2. Introduction

3. What is eclipse?
●
Eclipse is an integrated development
environment (IDE). It contains a base workspace
and an extensible plug-in system for customizing
the environment.
●
Eclipse is a Java-based application and, as such,
requires a Java runtime environment (JRE) in
order to run.

4. Contents
1. Steps to Install eclipse
● Method 1: Download from external links
● Method 2: Install from Ubuntu repos using apt
2. Setting the IDE for C Programming
● Choosing the perspective
● Changing Editor settings
● Selecting compiler
3. Creating a C Project
● Adding a new project
● Adding source (and header files)
● Editing source file
● Build the project
● Run & view the output
● Adding linker flags (say thread library)
● Passing CLI arguments
4. Debugging

5. Installation
●
Regardless of your operating system, you will
need to install some Java virtual machine (JVM).
●
You may either install a Java Runtime
Environment (JRE), or a Java Development Kit
(JDK).
●
If you aren't planning to use Eclipse for Java
development and want to save some disk space,
install a JRE.

6. JRE/JDK Sources
Installation in Linux systems
●
Most probably these packages will be installed
in your OS. In that case you can skip this step.
Methods to install JDK/JRE
Method 1
●
Download package from any of the following link
and install it
●
IBM JDK, OpenJDK and Oracle JDK
●
Download jdk/jre-xuversion-linux-x64/586.tar.gz
from anyone of the given links.
●
Unpack the tar.gz file and install the JDK/JRE
to /usr/jre or /usr/jdk folder

7. JRE/JDK Sources
Ubuntu & rpm based Linux
Method 2
For Ubuntu
●
From command line enter the command
sudo apt-get install openjdk-7-jdk or jre
For rpm based Linux
●
Download 32bit or 64bit rpm file from previous links
●
From command line
rpm -ivh jre-8uversion-linux-i586.rpm

8. Steps to Install
eclipse
Method 1(For Ubuntu)
●
From command line enter the command
sudo apt-get install eclipse-cdt
Method 2(From external links)
●
Download Eclipse IDE for C/C++ Developers
(CDT) from the here
●
tar -zxvf eclipse.XX.YY.tar.gz
●
cp -r eclipse.XX.YY /opt
Create a symlink in /usr/local/bin using
●
cd /usr/local/bin
●
ln -s /opt/eclipse/eclipse

9. Starting Eclipse

10. Getting started
●
To start Eclipse,Type eclipse in terminal and
enter.
●
The system will prompt you for a workspace.
The workspace is the location in your file
system in which Eclipse stores its
configuration and potentially other
resources, like projects.
$ eclipse &

11. Choosing
workspace
●
Select an empty directory and click the OK button.

12. Welcome window
● Close the welcome window

13. Start window
● After closing you will get a similar window

14. Setting the IDE for
C Programming

15. Choosing the
Perspective
●
A perspective is a visual container for a set of
views and editors (C/C++ , Java, XML, Android...)
●
You can switch Perspectives via the Window →
Open Perspective → Other... menu entry.

16. Continue...
● Select C/C++ from the window

17. Preferences
Settings
We need to change mainly two preferences
1.To change the editor preferences, select from the
menu Window → Preferences → General → Editors
→ Text editors
2.New CDT project
To change the editor preferences, select from the
menu Window → Preferences → C/C++ → New
C/C++ project

18. Continue...

19. Changing editor
settings
● Please check boxes as showing in below screenshot

20. Selecting
compiler
●
In new CDT project , select empty project from
project type and select Linux GCC from tool-
chain. Then press Make tool-chain preferred

21. Creating a C Project

22. Adding new
project
● To start a new project, right click on Project
explorer window and select New→C project or
press Ctrl + n from keyboard.
● Enter name for the project.

23. Adding source
● After creating project include folder will
automaticatlly created.
●
For adding files to the project click on the C+
button as shown below, or File menu -> New or
right click on project, from the navigation pane
select new
● Enter a name for the file.

24. Editing
Source file
● After adding file you can the file opened as given
below.
● Now you can start editing the source file.
● After editing press Cntrl + s to save.

25. Build the
Project
● To Build/make/compile project, click on the hammer
button as given below or press Cntrl + b or right
click on project folder and select 'Build Project'.
● In the console window you can see 'Build finished'
or errors if any (Fig 2).
● Binaries will be created in your folder

26. Run & output
● To run the executable file click on the play button
as shown below (Fig 1) or press Cntrl + F11 or
right click on project folder and select Run as →
Local C/C++ application.
● You can see the output of you project in the console
window (Fig 2).

27. Adding linker
flags
● To add linker flags right click on project, select
properties.
● Select C/C++ Build → Settings → GCC C linker →
Libraries
● Click Add button and enter the name of library to
link. Eg: For libpthread.so library enter pthread

28. Passing CLI
Arguments
● To pass command line arguments right click on
project, select Run as → Run configuration
● Select arguments and enter all arguments to pass

29. Debugging

30. How to debug
●
Debugging in eclipse is very easy
●
Select project you want to debug
●
Press F11 or click on debug button
●
It will change perspective automatically to
debug

31. Debug windows
●
In debug we can see one more window for
variables, breakpoints ,register values etc.
●
You have some buttons to control (step into, step
over,step return, restart, terminate. etc) the
execution while debugging.

32. Variable values
●
While debugging, in code window current
executing line will be highlighted.
●
You can see changing variables in yellow BG

33. Breakpoints
●
We can create breakpoints by double click on
border of the line.
●
A small dot will appear on border of that line.
