Eclipse C++ Setup

C++/Eclipse Development Environment

  • 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 STAGINGDIR environment variable, tool command prefix, tool path and GDB tool path in the project settings.

Setup Environment Variables. These variables are setup to tell eclipse where the tool-chain and the ESP-IDF core is located. Right Click on the Project Name. Select Properties. To add the environment variables: Expand C/C Build and click on Environment; Click on the Add Button as shown below.

C++ Development

- In order to develop C++ programs, it is first necessary to install C++ compilation tools

- Such tools translate programs in the C++ language into a language that computers can understand

- The languages that computers can understand are called machine language

Eclipse c++ cdt setup

- Different computers and operating systems use different machine languages

- Our first step is to install C++ compilation tools for your particular operating system

MacOS

- To translate C++ programs on Windows, we’ll install a package called XCode

- XCode contains compilers, debuggers, and tools for C++ software development

- Download Apple XCode IDE from the Mac App Store and follow installation instructions

Windows

- To translate C++ programs on Windows, we’ll install a package called MinGW

- MinGW contains compilers, debuggers, and tools for C++ software development

- Click the following link to download MinGW: http://www.mingw.org/download/installer

- This link will prompt to download a setup program called mingw-get-setup

- Save this program to a temporary location (e.g. Desktop or Downloads folder)

- Execute the setup program (double-click on the file)

- Select Install as shown below

- Select Continue when prompted to install in C:MinGW as shown below

- Select Continue after installation finishes as shown below

- Select Basic Setup on the left column and mark each of the following packages as shown or installation

- To mark each package for installation, select Mark for Installation in the pop-window as each one is selected

- Select Installation->Apply Changes on the window menu as shown below

- Select Apply as shown below to download and install the packages

- Note this could take some time depending on the speed of your internet connection and computer

- Select Close as shown below

- Select Installation->Quit in the window below to complete the installation

Eclipse Integrated Development Environment (IDE)

- Our next step is to install a complete environment to write, compile, debug, and execute our C++ programs

- Rather than using a standard text editor (e.g. WordPad) to write C++ source files, we will use an IDE

- IDEs provide a platform combining tools such as editing, compilation, and debugging in a single system

- Some IDEs can be used to develop programs in other languages in addition to C++ (e.g. Java, Python)

- There are a variety of IDEs that support C++ development (both free open-source and proprietary)

- Examples of free C++ IDEs include Microsoft Visual Studio, Studio Code, Code::Blocks, Dev-C++, and Eclipse

- A good comparison of IDEs for C++ as well as other languages can be found here

- For this course, we will be using the Eclipse IDE (which is actually written in Java)

- Since Eclipse is written in Java, our first step is to download a Java run-time environment (or JRE)

- This allows Eclipse to run correctly on our development machines

Install Java run-time environment (JRE)

- Go to the Oracle Java site and click on the “Java Download” button

- Next, click on the “Agree and Start Free Download” button

- This link will prompt to download a setup program beginning with “jre

- Save this program to a temporary location (e.g. Desktop or Downloads folder)

- Execute the setup program (double-click on the file) and follow installation instructions

Install Eclipse Integrated Development Environment (IDE)

- Our next step is to install the Eclipse IDE

- Please read the following carefully to install the correct version of Eclipse

- NOTE: To maintain consistency for our class, we will be using a specific version ONLY

- Please follow these directions exactly and install only the version indicated

- To begin the installation process, click on Eclipse IDE for C/C++ Developers (shown below)

- Identify the operating system of your home machine from the list in the table

- Note that Eclipse is available in 32 and 64-bit versions for different operating systems

Humanscale Diffrient World Office Task Desk Chair with Adjustable Duron Arms, Black Frame Pinstripe Back and Seat Mesh and Carpet Casters - Diffrient World is Humanscale's first foray into all-mesh task seating. Designer Niels Diffrient wanted to create the most minimal, full-function task chair ever made. Diffrient world office chair. Diffrient World is Humanscale’s first foray into all-mesh task seating. With an innovative tri-panel mesh backrest that provides custom back and lumbar support and lightweight design, Diffrient World is, like all of Humanscale’s products, simple, beautiful, and functional.

- NOTE: Be sure to select the correct version of Eclipse to match the Java JRE version installed above

- Problems are likely to arise if there is a mismatch between 32/64 between Eclipse and Java installs

- Once you've identified the correct version, click on the OS link and download the file to your desktop

- After the file is downloaded, simply extract the file in the same location (e.g. Desktop)

- Unlike other installation packages, you do not need to run a setup or installer program

- A folder is extracted with the same name (e.g. eclipse-cpp-neon-3-win32-x86_64)

- Inside this folder is a single folder named eclipse with everything contained within the folder

- Shown below, this folder contains the executable (eclipse.exe) you select to run Eclipse

- Move the entire eclipse directory to any desired location on your system

- For on-campus students, copy this folder to your USB to use Eclipse in class

- You might want to create a shortcut of eclipse.exe on your desktop for easy access

Eclipse C++ Setup Mac

Launching Eclipse

- To launch the Eclipse IDE, double-click the eclipse.exe program located in the eclipse folder

- If Eclipse cannot find your Java installation (to execute the Java VM), you might see the following:

- This could also occur if there is a mismatch in bit versions (32/64) to the Java installed

- Make sure you have installed the same bit versions (32 or 64) of Java and Eclipse

- Successful execution of eclipse.exe will prompt for a workspace location to store your projects

- This workspace is simply a folder that Eclipse will use to store created projects

- For on-campus students, create a folder on your USB and use this folder as your workspace

- For on-line students, simply use the default workspace location as shown above

- First time execution may bring up the Welcome screen below (which you can return to anytime)

- The menu item Help->Welcome will show this screen

- Click the ‘X’ on the Welcome tab to remove this screen and show the IDE environment (below)

- The next step is to become familiar with the Eclipse environment and create your first program

Add C++ To Eclipse

- Read and proceed through the Eclipse C++ Help tutorial (also listed in the Schedule)
