Eclipse is an open-source Integrated Development Environment (IDE) supported by IBM. The mother site is @ www.eclipse.org. Eclipse is popular for Java project development. It also supports C/C++, PHP, Python, Perl, and other web project developments via extensible plug-ins. Eclipse is cross-platform and runs under Windows, Linux and Mac OS.

How to Install Eclipse C/C++ Development Tool (CDT) 8.1.2 for Eclipse 4.2.2 (Juno)

Eclipse has installed the Android Development Tools. After restart, eclipse will ask the path for Android SDK installation or you can allow eclipse to install Android SDK on default path. To check the successful installation, click on Window menu in eclipse. Eclipse IDE Kepler; SR2; Eclipse Standard 4.3.2; Eclipse Installer; Eclipse Packages; Eclipse Developer Builds. 2021-09 M1; This package was released on. Eclipse Web Tools Platform (WTP) 3.5 now supports the development of Java EE 7 applications. Stardust 1.0 provides a complete Business Process Management (BPM) suite of tools and runtimes. Orion 3.0 includes significant usability features and easier deployment to Java applications servers. Business Intelligence and Reporting Tools (BIRT. But there are two other thing: an up-to-date nightly build of the new Eclipse version Luna which will be released with Java 8 support and a patch for the current Eclipse version Kepler! Since it is sometimes (= always) hard to find the correct Eclipse version on eclipse dot org or anything useful at all, here is how to do it. In Eclipse, import the project created by running ant eclipse by selecting File - Import - General - 'Existing Projects into Workspace' and then browsing to the kepler directory created above, hit Finish. The build may take 10-15 minutes, see Bug 4191. KarDoclet.java uses doclet code from tools.jar.

Step 0: Install MinGW GCC or Cygwin GCC

To use Eclipse for C/C++ programming, you need a C/C++ compiler. On Windows, you could install either MinGW GCC or Cygwin GCC. Choose MinGW if you are not sure, because MinGW is lighter and easier to install, but having less features.

MinGW GCC: Read 'How to Install MinGW'.
Cygwin GCC: Read 'How to Install Cygwin'. Make sure that you select 'gcc', 'g++', 'gdb', and 'make' packages under the 'Devel' (Development) category - these packages are not part of the default installation.

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.

Step 2: Configuration

You do NOT need to do any configuration, as long as the Cygwin or MinGW binaries are included in the PATH environment variable. CDT searches the PATH to discover the C/C++ compilers.

Writing your First C/C++ Program in Eclipse

C++ Program

Step 0: Launch Eclipse

Start Eclipse by running 'eclipse.exe' in the Eclipse installed directory.
Choose an appropriate directory for your workspace (i.e., where you would like to save your works).
If the 'welcome' screen shows up, close it by clicking the 'close' button.

Step 1: Create a new C++ Project

For each C++ application, you need to create a project to keep all the source codes, object files, executable files, and relevant resources.

To create a new C++ project:

Eclipse Kepler Download

Choose 'File' menu ⇒ 'New' ⇒ Project.. ⇒ C/C++ ⇒ C++ project.
The 'C++ Project' dialog pops up.
1. In 'Project name' field, enter 'FirstProject'.
2. In 'Project Types' box, select 'Executable' ⇒ 'Empty Project'.
3. In 'Toolchains' box, choose your compiler, e.g., 'Cygwin GCC' or 'MinGW GCC' ⇒ Next.
The 'Select Configurations' dialog appears. Select both 'Debug' and 'Release' ⇒ Finish.

Step 2: Write a Hello-world C++ Program

In the 'Project Explorer' (leftmost panel) ⇒ Right-click on 'FirstProject' (or use the 'File' menu) ⇒ New ⇒ Source File.
The 'New Source File' dialog pops up.
1. In 'Source file' field, enter 'Hello.cpp'.
2. Click 'Finish'.
The source file 'Hello.cpp' opens on the editor panel (double-click on 'test.cpp' to open if necessary). Enter the following codes:

If 'Unresolved Inclusion Error'

If error 'unresolved inclusion' appears next to #include statement, the 'include paths for headers' are not set properly. Select 'Project' menu ⇒ Properties ⇒ C/C++ General ⇒ Paths and Symbols ⇒ In 'Includes' tab:

For Cygwin GCC:

'Add' the following directories to 'GNU C', where $CYGWIN_HOME is your Cygwin installed directory:
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xinclude
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xinclude-fixed
- $CYGWIN_HOMEusrinclude
- $CYGWIN_HOMEusrincludew32api
'Add' the following directories to 'GNU C++', where $CYGWIN_HOME is your Cygwin installed directory:
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xincludec++
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xincludec++i686-pc-cygwin
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xincludec++backward
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xinclude
- $CYGWIN_HOMElibgcci686-pc-cygwin4.5.xinclude-fixed
- $CYGWIN_HOMEusrinclude
- $CYGWIN_HOMEusrincludew32api

For MinGW GCC:

'Add' the following directories to 'GNU C', where $MINGW_HOME is your MinGW installed directory:
- $MINGW_HOMElibgccmingw324.6.xinclude
- $MINGW_HOMEinclude
- $MINGW_HOMElibgccmingw324.6.xinclude-fixed
'Add' the following directories to 'GNU C++', where $MINGW_HOME is your Cygwin installed directory:
- $MINGW_HOMElibgccmingw324.6.xincludec++
- $MINGW_HOMElibgccmingw324.6.xincludec++mingw32
- $MINGW_HOMElibgccmingw324.6.xincludec++backward
- $MINGW_HOMElibgccmingw324.6.xinclude
- $MINGW_HOMEinclude
- $MINGW_HOMElibgccmingw324.6.xinclude-fixed

NOTE: To find the header paths, you can do a search on headers such as 'stdio.h' (for C) and 'iostream' (for C++) under the Cygwin or MinGW installed directory.

Note: If you encounter 'error while loading shared libraries' during link. Install 'libmpfr4' in cygwin.

Step 3: Compile/Build

Right-click on the 'FirstProject' (or use the 'Project' menu) ⇒ choose 'Build Project' to compile and link the program.

Step 4: Run

To run the program, right-click on the 'FirstProject' (or anywhere on the source 'test.cpp', or select the 'Run' menu) ⇒ Run As ⇒ Local C/C++ Application ⇒ (If ask, choose Cygwin's gdb debugger) ⇒ The output 'Hello, world!' appears on the 'Console' panel.

NOTE: You need to create a new C++ project for EACH of your programming problems. This is messy for writing toy programs!

C Program

Follow the same steps as above. Create a 'C Project' (instead of 'C++ Project'). Try the following Hello-world program (called 'Hello.c').

C++ Program with Makefile

In the previous examples, we use so-called managed-make where Eclipse automatica
