<h2>Tutorial: Creating a simple application</h2>
|
|
|
15 |
|
|
|
16 |
<p>In this tutorial, you will use the CDT to create a simple 'Hello World' application.
|
|
|
17 |
This tutorial describes the process of creating a new C++ project where the build is
|
|
|
18 |
automatically managed by the CDT, and running the program.</p>
|
|
|
19 |
|
|
|
20 |
<p>Note: In earlier versions of the CDT, there were two separate project types:
|
|
|
21 |
Managed make (automatically generated a makefile)
|
|
|
22 |
and Standard make (required the user's makefile to build).
|
|
|
23 |
Now with CDT, you now select a project type, and that determines what build system will be used.</p>
|
|
|
24 |
|
|
|
25 |
<p>To create a simple "Hello World" application using the CDT, you will perform the following steps:</p>
|
|
|
26 |
|
|
|
27 |
<h3> Step 1: Creating a project</h3>
|
|
|
28 |
<ol>
|
|
|
29 |
<li>Select <b>File > New > Project</b>.</p>
|
|
|
30 |
<p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic02.png')">Click here to see an illustration (displayed in a separate window)</a>.</p><br></li>
|
|
|
31 |
|
|
|
32 |
<li>Select the type of project to create. For this tutorial, expand the <b>C++</b> folder and select <b>C++ Project</b> and click <b>Next</b>.
|
|
|
33 |
<p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic03a.png')">Click here to see an illustration.</a><br></p>
|
|
|
34 |
<p><br>The <b>C++ Project</b> wizard opens.</p>
|
|
|
35 |
<a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic04.png')">Click here to see an illustration.</a><br></p>
|
|
|
36 |
<p><br>By default, the CDT filters the <b>Toolchain</b> and <b>Project types</b> that it displays in those lists based on the language support for the C++ Project wizard you selected for this tutorial.</p>
|
|
|
37 |
</li><br>
|
|
|
38 |
<li><p>In the <b>Project name</b> field, type a name for the project, such as <b>Hello World</b>.</p>
|
|
|
39 |
<br>
|
|
|
40 |
<li><p>From the <b>Project types</b> list, expand <b>Executable</b> and select <b>Hello World C++ Project</b>. This project type provides a simple Hello World application in C++, and the makefile is automatically created by the CDT.</p>
|
|
|
41 |
<br>
|
|
|
42 |
<li><p>Select a required toolchain from the <b>Toolchain</b> list.</p>
|
|
|
43 |
<br>
|
|
|
44 |
<p>A toolchain is a set of tools (such as a compiler, linker, and assembler) intended to build your project.
|
|
|
45 |
Additional tools, such as a debugger, can be associated with a toolchain.
|
|
|
46 |
There can be several toolchains available, depending on the compilers installed on your system.</p>
|
|
|
47 |
<br>
|
|
|
48 |
<li><p>Click <b>Next</b>.</p>
|
|
|
49 |
<br>
|
|
|
50 |
<p>The Select Configurations window displays a list of configurations based on the project type and toolchain(s) you selected earlier.
|
|
|
51 |
<br>
|
|
|
52 |
<a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic07.png')">Click here to see an illustration.</a></p>
|
|
|
53 |
<br>
|
|
|
54 |
<li><p>Optional: If you want to change the default project settings, click <b>Advanced Settings</b>.</p>
|
|
|
55 |
<br>
|
|
|
56 |
<p>This opens the project properties dialog for your new project allowing you change any of the project specific settings,
|
|
|
57 |
such as includes paths, compiler options, and libraries.</p>
|
|
|
58 |
<p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic21.png')">Click here to see an illustration.</a></p>
|
|
|
59 |
<br>
|
|
|
60 |
<li>If you clicked <b>Next</b> at Step 6, you can specify the basic properties for the new project, such as your name, copyright, and source information.</p>
|
|
|
61 |
<p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic22.png')">Click here to see an illustration.</a></p>
|
|
|
62 |
<br>
|
|
|
63 |
<li><p>Click <b>Finish</b>.</p>
|
|
|
64 |
<br>
|
|
|
65 |
<li><p>If the <b>C++ perspective</b> is not currently set as the default, you are prompted to determined if you would like to this project to be associated with the C/C++ perspective. Click <b>Yes</b>.
|
|
|
66 |
<br><p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_cpp_perspectx.png')">Click here to see an illustration.</a></p>
|
|
|
67 |
<br>
|
|
|
68 |
<p>A project is created with the default settings and a full set of configurations based on the project type and toolchain you selected.
|
|
|
69 |
You should now see the new project in C/C++ Projects view.</p>
|
|
|
70 |
<p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic12.png')">Click here to see an illustration.</a></p>
|
|
|
71 |
<br>
|
|
|
72 |
</ol>
|
|
|
73 |
|
|
|
74 |
<h3>Step 2: Reviewing the code and building the project</h3>
|
|
|
75 |
<ol>
|
|
|
76 |
<li>From the Project Explorer in the C++ Projects View, double-click the .cpp file that was created for your project, for example, <tt>Hello World.cpp</tt>.
|
|
|
77 |
<p>Note that the file may be within a folder inside the project, e.g. the "src" folder.</p>
|
|
|
78 |
<p>This file opens in a default editor. It contains C++ template code for the Hello World example project you selected earlier.</p>
|
|
|
79 |
<br>
|
|
|
80 |
<p><b>Note:</b> You can specify a different editor, and add or modify existing code templates in <b>Window > Preferences</b>.</p><p>In addition, the <b>Outline</b> view has also been populated
|
|
|
81 |
with objects created from your code.</p> <p><a href="javascript:void(0)" onClick="newWin('../images/cdt_w_basic13.png')">Click here to see an illustration.</a></p>
|
|
|
82 |
</li>
|
|
|
83 |
<li>Optional: You can type additional code in this file, and then save the changes by clicking <span
|
|
|
84 |
style="font-weight: bold;">File > Save</span>, or pressing <b>CTRL+S</b>.
|
|
|
85 |
|
|
|
86 |
<p><br>Next, you will need to build your project before you can run it.</p><br></li>
|
|
|
87 |
<li>Build your project by pressing <b>CTRL+B</b>, or select the project from the Project Explorer tab in the C++ Projects view and select <b>File > Build Project</b>.</p>
|
|
|
88 |
<p><br><b>Note:</b> If a build generates any errors or warnings, you can see those in the Problems view. If you encounter difficulty, see the topics <a href="../concepts/cdt_c_build_over.htm">Building C/C++ projects</a> and <a href="../concepts/cdt_c_before_you_begin.htm">Before you begin</a><br>.</p></li>
|
|
|
89 |
<li>Read through the build messages in the <b>Console</b> view.
|
|
|
90 |
The project should build successfully.</p>
|
|
|
91 |
<br>
|
|
|
92 |
<p>You will also see the <b>Outline</b> view has also been populated
|
|
|
93 |
with objects created from your code. If you select an item from the <b>Outline</b> view, the
|
|
|
94 |
corresponding text in the editor is highlighted.</p><br>
|
|
|
95 |
</ol>
|
|
|
96 |
|
|
|
97 |
<h3>Step 3: Running the application</h3>
|
|
|
98 |
|
|
|
99 |
<p>To run your application:</p>
|
|
|
100 |
<ol>
|
|
|
101 |
<li>Within the C/C++ Perspective, click <b>Run > Run Configurations...</b>.<p><br></p></li>
|
|
|
102 |
<li>Select <b>C/C++ Application</b>.<p><br></p></li>
|
|
|
103 |
<li>Click <b>New</b>.<p><br></p></li>
|
|
|
104 |
|
|
|
105 |
<p>A new Run Configuration is created. Its name and path to the executable are provided by the project ('Hello World' in our case).
|
|
|
106 |
|
|
|
107 |
<li>Click <b>Run</b>.<p><br></p>
|
|
|
108 |
|
|
|
109 |
<p>Now, you should see the Hello World application running in the <b>Console</b> view.
|
|
|
110 |
The <b>Console</b> also shows which application is running in a title bar.</p><br></li>
|
|
|
111 |
|
|
|
112 |
<li>You can click the other views to see the information that they contain.
|
|
|
113 |
</ol>
