Eclipse is widely used to develop applications using Java, PHP, and C/C++ as the programming languages. It's one of the most popular open-source IDE among the developers. This tutorial provides all the steps required to install Eclipse for C/C++ Developers to develop applications in C or C++.

In this tutorial, we will discuss how to install Eclipse for C++ or C development on the popular Linux distribution i.e. Ubuntu. It provides several features for C/C++ development including IntelliSense, Debugging, etc. This tutorial provides all the steps required to install Eclipse on Ubuntu 18.04 LTS, though the steps should be similar for other Linux systems.

It assumes that Java is already installed on the system. You may also be interested in How To Install OpenJDK 12 On Ubuntu and How To Install Java 11 On Ubuntu.

Notes: It assumes that GCC is already installed on the system. You may also be interested in How To Install GCC On Ubuntu 18.04 LTS to install the latest GCC on the popular Debian based Linux distribution - Ubuntu.

Step 1 - Download Eclipse

Open the Eclipse Packages Page to view the various packages distributed by the Eclipse Foundation. It shows the package for C/C++ as shown in Fig 1.

Click on the Download Button to start the download. You may also choose other mirror sites as listed on the Downloads Page.

Step 2 - Install Eclipse

In this step, we will install Eclipse for C/C++ Developers using the zip downloaded in the previous step. Extract the download to your preferred location having sufficient space on the disk. The extract will look like the one as shown in Fig 3.

Step 3 - Desktop Shortcut

In this step, we will create the desktop shortcut to execute it from the desktop using the executable available in the bin directory.

We will install the GNOME panel and use the same to create a desktop shortcut to execute the Eclipse installed by us in previous steps.

# Refresh Packages Index
sudo apt-get update

# Install GNOME Panel
sudo apt-get install --no-install-recommends gnome-panel

# Create Desktop icon
gnome-desktop-item-edit ~/Desktop/ --create-new

Now configure the Eclipse installation as shown in Fig 4. We will use the Eclipse icon available in the root of the installation directory.

Step 4 - Launch Eclipse

Now execute the Eclipse using the executable. In case you execute it using the desktop shortcut, it will ask for system permission as shown in Fig 5.

Step 5 - Getting started with C++ - Hello World

In this step, we will create the hello.cpp file and update it to print Hello World on the Console. Right-click on the File, hover over the New Option and click on the Project Option. It will show options to create a C++ Project. Click on the C/C++ Project option to start creating the project.

The New Project Dialog will show options to choose Project Type as shown in Fig 10.

Step 6 - Getting started with C - Hello World

In this step, we will create the hello.c file and update it to print Hello World on the Console.

Create a C Project with the name HelloC following the same steps as we did for C++ Project. Also, create a file hello.c with the source code as shown in Fig 16.

Follow the same steps as we did with HelloCPP Project to build and execute it as Local Application. It will show the output as shown in Fig 17 and Fig 18.
