Step 1: Install Eclipse C/C++ Development Tool (CDT)
Two ways to install CDT, depending on whether you have previously installed an Eclipse:
- If you have already installed "Eclipse for Java Developers" or other Eclipse packages, you could install the CDT plug-in as follows:
Launch Eclipse ⇒ Help ⇒ Install New Software ⇒ In "Work with" field, pull down the drop-down menu and select "Kepler - http://download.eclipse.org/releases/kepler" (or juno for Eclipse 4.2; or helios for Eclipse 3.7).
In "Name" box, expand "Programming Language" node ⇒ Check "C/C++ Development Tools" ⇒ "Next" ⇒ ... ⇒ "Finish". - If you have not install any Eclipse package, you could download "Eclipse IDE for C/C++ Developers" from http://www.eclipse.org/downloads, and unzip the downloaded file into a directory of your choice.
