Eclipse Ide C Programming

  1. Eclipse is an IDE.It will help you write applications in c/,but it will not compile your program as Eclipse does not comes with a compiler pre-configured. You need to install a compiler to run your application. Eclipse is capable to use many c/c compilers,some are: 1.Cygwin.
  2. Eclipse uses plug-ins to provide all the functionality within and on top of the run-time system. Its run-time system is based on Equinox, an implementation of the OSGi core framework specification. In addition to allowing the Eclipse Platform to be extended using other programming languages, such as C and Python, the plug-in framework allows the Eclipse Platform to work with.

Using Eclipse for C Programming George Ferguson [email protected] September 2018 Updated Summer 2020 Abstract Students are used to using the Eclipse IDE for programming in Java. This document de-scribes how to install and use Eclipse for programming in C (and C). Amazingly, it isn’t as easy as it should be.

  • What are Workspaces, perspectives, and projects?
  • Do I need to create a new workspace for each program I want to develop?

· What do I need to do to get a simple C++ program to compile and execute?
Create a Workspace (or use and existing one) .
Open the C/C++ perspective.
Create a C/C++ project.
Add files to the project.
Build the project.
Run the program.

· What are Workspaces, Perspectives and Projects?

Workspaces :
Workspaces are directories that the Eclipse IDE stores information and files associated with one or more projects, typically grouping related projects together. For example, when taking a programming class, you typically create one workspace (directory) to hold all the projects associated with that class's assignments.

Projects :
Projects contain and manage programs that are to be combined together to create a single executable program (or a library ). Typically one creates a new project for each programming task rather than re-using existing projects. If one is doing programming for a class, it is customary to create a separate project for each assignment.

Perspective :
An Eclipse perspective is a collection of windows in the IDE that are associated with a particular Eclipse progamming tool. For example, there is a Java perspective that one opens when programming in Java and a C/C++ perspective that one opens when programming in C/C++.

·Do I need to create a new workspace for each program I want to develop? Eclipse Ide C Programming
No, one creates a new project for each program, and places the new projects in an existing workspace.

This article describes how to setup Eclipse IDE for C/C++ Developers and OpenWrt SDK to build and debug programs running on LinkIt Smart 7688 development board.

After proper setup, Eclipse will be able to build, upload and attach debugger to your C/C++ program that runs on target LinkIt Smart 7688 development board. This can be pretty helpful if you are writing your own C/C++ programs.

  • LinkIt Smart 7688 or LinkIt Smart 7688 Duo development platform.
  • Mac OS X or Ubuntu Linuxmachine to run the OpenWrt SDK. If you haven't set it up yet, follow the cross compilation instructions to make sure the SDK is ready to use.
  • Eclipse IDE for C/C++ Developers.
  • Eclipse IDE requires JVM. Follow the IDE instructions to install the corresponding JVM version.
  • Install and setup SFTP on LinkIt Smart 7688 development board with opkg.
  • Install Eclipse C/C++ GCC Cross Compiler Support and Remote System explorer End-User Runtime. Newer versions of Eclipse may have these packages installed already.
  • Create an Eclipse C/C++ Cross GCC project.
  • Setup STAGING_DIR environment variable, tool command prefix, tool path and GDB tool path in the project settings.
  • Build and setup sign-in password to LinkIt Smart 7688 development board.
  • The IDE will automatically build, upload and execute the resulting binary.

Download and setup OpenWrt SDK

Follow the cross compilation guide to download and install the SDK first.

Enable SFTP on LinkIt Smart 7688 development board

First we need to prepare the board to enable the SFTP service. This allows Eclipse IDE to upload binaries and debug files to the board.

Make sure your board is connected to the internet and you have access to the system console. Enter following commands to install and enable the SFTP service.

Install and setup Eclipse IDE for C/C++ developers

Download the C/C++ package of the Eclipse IDE:

  1. Download and install Eclipse IDE for C/C++ Developers.
  2. Depending on your system, you may need to install JDK (not JRE) if the Eclipse IDE complains about incorrect JVM version.

Create and configure C project

Create a Hello World project that uses cross compilation toolchain from the LinkIt Smart 7688 OpenWrt SDK. Eclipse spring plugin.

  1. Launch the IDE, click File, then New and then Project.
  2. In the New Project wizard, select C Project and click Next.
  3. Select Hello World ANSI C Project under Executables and Cross GCC from Toolchains, as shown below.
    • If there is no Cross GCC option, install C/C++ GCC Cross Compiler Support.
      • To install the Cross Compiler Support, Navigate to Help then Install new Software.., find C/C++ GCC Cross Compiler Support (org.eclipse.cdt.build.crossgcc) and install it.
  4. Continue the steps in the wizard until you see the Cross GCC Command settings, as shown below:
  5. Click Finish and the wizard to create the project.
  6. Setup the STAGING_DIR environment variable required by OpenWrt SDK. From the menu click Project then Properties.
  7. Navigate to Environment under C/C++ Build. Here you can set additional environment variables required by the build system.
    • Variable: STAGING_DIR
    • Value: OpenWrt_SDK/staging_dir/ where OpenWrt_SDK is the path to your OpenWrt SDK directory. An example setup is shown below:

Since the code is already generated by the wizard, proceed to build the project. Click Project then Build All from the main menu. If the setup is correct, you should see a build log similar to this:

If there are compiling or linking errors, check the settings in the previous steps.

Next, configure the IDE to upload the executable file automatically and debug with gdb remotely.

  1. Make sure your computer is in the same Wi-Fi network as LinkIt Smart 7688 development board. In this example you'll use the default domain name mylinkit.local. Make sure you can access the system console with SSH.
  2. Click Run then Debug Configurations.. from the main menu.
  3. In the dialog, select C/C++ Remote Application then click New.
  4. Click New.. connection, as shown below:
    SetHost nameto mylinkit.local. Also set Default User Id to root.

  5. Define Remote Absolute File Path for C/C++ Application as /tmp/HelloWorld. You may also browse for another path.
  6. Now select the Debug tab. Set the GDB Debugger path to

    where OpenWrt_SDK is the path to the OpenWrt SDK.

  7. Click Apply then Debug. The IDE will now upload the built executable to LinkIt Smart 7688 development board through SFTP service. Enter the root password of the board, if the IDE prompts you to do so.
  8. The IDE now starts a gdbserver on the board, then connects Eclipse debug view to it. By default, it will break at the first line of the main() function.

You've now successfully built and debugged and application on Eclipse IDE with LinkIt Smart 7688 as a target device. You may use this reference application for further development.
