This tutorial describes the process of creating a new C++ project where the build is automatically managed by the CDT, and running the program.</p> <p><strong>NOTE</strong>: In earlier versions of the CDT, there were two separate project types: Managed make (automatically generated a makefile) and Standard make (required the user's makefile to build). Now with CDT, you just select a project type, and that determines what build system to use.</p> <p>To create a simple "Hello World" application using CDT, perform the following general steps:</p> <ol> <li><a href="#cdt_create">Creating a project</a></li> <li><a href="#cdt_build">Reviewing the code and building the project</a></li> <li><a href="#cdt_running">Running the application</a></li> </ol> <hr> <h2> Step 1: <a name="cdt_create"></a>Creating a project</h2> <ol> <li>Select <strong>File > New > Project</strong>.<br> <br> <img src="../images/cdt_w_basic02.png" alt="Select File > New > Project menu option" width="591" height="183"> <p><br> </p> </li> <li>Select the type of project to create. For this tutorial, expand the <strong>C++</strong> folder and select <strong>C++ Project</strong> and click <strong>Next</strong>.<br> <br> <img src="../images/cdt_w_basic03a.png" alt="Select project type" width="525" height="500"><br> <br> </li> <li> <p>The <strong>C++ Project</strong> wizard opens.<br> </p> <p><img src="../images/cdt_w_basic04.png" alt="C++ project wizard" width="525" height="576"><br> <br>By default, the CDT filters the <strong>Toolchain</strong> and <strong>Project types</strong> that it displays in those lists based on the language support for the C++ Project wizard you selected for this tutorial.</p> <br> <ol style="list-style-type: lower-alpha;"> <li>In the <strong>Project name</strong> field, type a name for the project, such as <strong>HelloWorld</strong>. <p><br> </p> </li> <li>From the <strong>Project type</strong> list, expand <strong>Executable</strong> and select <strong>Hello World C++ Project</strong>. This project type provides a simple Hello World application in C++, and the makefile is automatically created by the CDT. <p><br> </p> </li> <li>Select a required toolchain from the <strong>Toolchain</strong> list. <p><br> </p> <p>A toolchain is a set of tools (such as a compiler, linker, and assembler) intended to build your project. Additional tools, such as a debugger, can be associated with a toolchain. There can be several toolchains available, depending on the compilers installed on your system.</p> <p><br> </p> </li> <li>Click <strong>Next</strong>. </li> </ol> <br> </li> <li>Specify the <strong>Basic Properties</strong> for the new project, such as your author, copyright, and source information, then click <strong>Next</strong>.<br> <br> <img src="../images/cdt_w_basic06a.png" alt="Basic properties of a project" width="525" height="576"><br> <br> </li> <li> <p>The <strong>Select Configurations</strong> page displays a list of configurations based on the project type and toolchain(s) selected earlier. <br> <br> <img src="../images/cdt_w_basic07.png" alt="Select configurations page" width="525" height="576"><br> <br> <strong>OPTIONAL</strong>: If you want to change the default project settings, click <strong>Advanced Setting</strong> to open the <a href="../reference/cdt_u_prop_all.htm">Project Properties</a> dialog for your new project allowing you change any of the project specific settings, such as includes paths, compiler options, and libraries.<br> <br> </p></li> <li><p>Click <strong>Finish</strong>.<br> </p></li> </ol> <p><strong>NOTE</strong> If the <strong>C++ perspective</strong> is not currently set as the default, you are prompted to determine if you would like to this project to be associated with the C/C++ perspective. Click <strong>Yes</strong>.<br> </p> <p>A project is created with the default settings and a full set of configurations based on the project type and toolchain you selected. You should now see the new project in <a href="../reference/cdt_u_project_explorer_view.htm">Project Explorer</a> view.</p> <p> <img src="../images/cdt_w_basic12.png" alt="New project displayed in the Project Explorer view" width="423" height="283"></p> <br> <hr> <br> <h2>Step 2: <a name="cdt_build" id="cdt_build"></a>Reviewing the code and building the project</h2> <ol> <li>From the <strong>Project Explorer</strong> view, double-click the .cpp file created for your project, for example, <span class="typewriter">HelloWorld.cpp</span>. You'll find it within the project "<span class="typewriter">src</span>" folder.<br> <br> <p>This file opens in a default editor. It contains C++ template code for the Hello World example project you selected earlier.
