Article
02/04/2013

This walkthrough demonstrates how to use MSBuild to build a Visual C++ project at a command prompt. You will learn how to create the C++ source files and an XML-based project file for a Visual C++ console application. After building the project, you will learn how to customize the build process.

This walkthrough illustrates the following tasks:

Creating the C++ source files for your project.
Creating the XML MSBuild project file.
Using MSBuild to build your project.
Using MSBuild to customize your project.

Prerequisites

You need the following to complete this walkthrough:

Visual Studio 2010
A general understanding of the MSBuild system.

Creating the C++ Source Files

In this walkthrough you will create a project that has a source file and a header file. The source file main.cpp contains the main function for the console application. The header file main.h contains code to include the iostream header file. You can create these C++ files by using Visual Studio or a text editor.

To create the C++ source files for your project

Create a directory for your project.

Create a file that is named main.cpp and add the following code to this file:

// main.cpp : the application source code.
#include <iostream>
#include "main.h"
int main()
{
   std::cout << "Hello, from MSBuild!\n";
   return 0;
}

Create a file that is named main.h and add the following code to this file:

// main.h: the application header code.
/* Additional source code to include. */

Creating the XML MSBuild Project File

An MSBuild project file is an XML file that contains a project root element (<Project>). In the following example project, the <Project> element contains seven child elements:

Three item group tags (<ItemGroup>) that specify project configuration and platform, source file name, and header file name.
Three import tags (<Import>) that specify the location of Microsoft Visual C++ settings.
A property group tag (<PropertyGroup>) that specifies project settings.

To create the MSBuild project file

Use a text editor to create a project file that is named myproject.vcxproj, and then add the following root <Project> element. Insert the elements in the following procedure steps between the root <Project> tags:
```
<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="https://schemas.microsoft.com/developer/msbuild/2003">
</Project>
```

Add the following two <ProjectConfiguration> child elements in an <ItemGroup> element. The child element specifies debug and release configurations for a 32-bit Windows operating system:

<ItemGroup>
   <ProjectConfiguration Include="Debug|Win32">
      <Configuration>Debug</Configuration>
      <Platform>Win32</Platform>
   </ProjectConfiguration>
   <ProjectConfiguration Include="Release|Win32">
      <Configuration>Release</Configuration>
      <Platform>Win32</Platform>
   </ProjectConfiguration>
</ItemGroup>

Add the following <Import/> element that specifies the path of the default C++ settings for this project:
```
<Import Project="$(VCTargetsPath)\Microsoft.Cpp.default.props" />
```

Add the following property group element (<PropertyGroup>) that specifies two project properties:

<PropertyGroup>
   <ConfigurationType>Application</ConfigurationType>
   <ShowAllFiles>false</ShowAllFiles>
</PropertyGroup>

Add the following <Import/> element that specifies the path of the current C++ settings for this project:
```
<Import Project="$(VCTargetsPath)\Microsoft.Cpp.props" />
```
Add the following <ClCompile> child element in an <ImportGroup> element. The child element specifies the name of the C/C++ source file to compile:
```
<ItemGroup>
   <ClCompile Include="main.cpp" />
</ItemGroup>
```
Add the following <ClInclude> child element in an <ImportGroup> element. The child element specifies the name of the header file for the C/C++ source file:
```
<ItemGroup>
   <ClInclude Include="main.h" />
</ItemGroup>
```
Add the following <Import> element that specifies the path of the file that defines the target for this project:
```
<Import Project="$(VCTargetsPath)\Microsoft.Cpp.Targets" />
```

Complete Project File

The following code shows the complete project file that you created in the previous procedure.

<Project DefaultTargets="Build" ToolsVersion="4.0" xmlns="https://schemas.microsoft.com/developer/msbuild/2003">
  <ItemGroup>
    <ProjectConfiguration Include="Debug|Win32">
      <Configuration>Debug</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
    <ProjectConfiguration Include="Release|Win32">
      <Configuration>Release</Configuration>
      <Platform>Win32</Platform>
    </ProjectConfiguration>
  </ItemGroup>
  <Import Project="$(VCTargetsPath)\Microsoft.Cpp.default.props" />
  <PropertyGroup>
    <ConfigurationType>Application</ConfigurationType>
    <ShowAllFiles>false</ShowAllFiles>
  </PropertyGroup>
  <Import Project="$(VCTargetsPath)/Microsoft.Cpp.props" />
  <ItemGroup>
    <ClCompile Include="main.cpp" />
  </ItemGroup>
  <ItemGroup>
    <ClInclude Include="main.h" />
  </ItemGroup>
  <Import Project="$(VCTargetsPath)\Microsoft.Cpp.Targets" />
</Project>

Using MSBuild to Build Your Project

Type the following command at the command prompt to build your console application:

msbuild myproject.vcxproj /p:configuration=debug

MSBuild creates a directory for the output files, and then compiles and links your project to generate the Myproject.exe program. After the build process finishes, use the following command to run the application:

myproject

The application should display "Hello, from MSBuild!" in the console window.

Customizing Your Project

MSBuild enables you to execute predefined build targets, apply user-defined properties, and use custom tools, events, and build steps. This section illustrates the following tasks:

Using MSBuild with build targets.
Using MSBuild with build properties.
Using MSBuild with different toolsets.
Adding MSBuild customizations.

Using MSBuild with Build Targets

A build target is a named set of predefined or user-defined commands that can be executed during the build. Use the target command-line option (/t) to specify a build target. In the case of the myproject example project, the predefined clean target deletes all files in the debug folder and creates a new log file.

At the command prompt, type the following command to clean myproject.

msbuild myproject.vcxproj /t:clean

Using MSBuild with Build Properties

The property command-line option (/p) enables you to override a property in your project build file. In the myproject example project, the release or debug build configuration is specified by the Configuration property. And the operating system that is intended to run the built application is specified by the Platform property.

At the command prompt, type the following command to create a debug build of the myproject application that is intended to run on 32-bit Windows.

msbuild myproject.vcxproj /p:configuration=debug /p:platform=win32

Assume that the myproject example project also defines a configuration for 64-bit Windows, and another configuration for a custom operating system named myplatform.

At the command prompt, type the following command to create a release build that runs on 64-bit Windows.

msbuild myproject.vcxproj /p:configuration=release /p:platform=x64

At the command prompt, type the following command to create a release build for myplatform.

msbuild myproject.vcxproj /p:configuration=release /p:platform=myplatform

Using MSBuild with a Different Toolset

If you have both the Visual C++ 9.0 and 10.0 libraries (toolsets) installed, MSBuild can build applications for either Visual C++ 9.0 or 10.0. To specify the Visual C++ 9.0 toolset, add the following property group element to the Myproject.vcxproj project file after the Microsoft.Cpp.props <Import /> element:

<PropertyGroup>
    <PlatformToolset>v90</PlatformToolset>
</PropertyGroup>

To rebuild your project with the Visual C++ 9.0 toolset, type either of the following commands:

msbuild myproject.vcxproj /p:PlatformToolset=v90 /t:rebuild 
msbuild myproject.vcxproj /t:rebuild

Adding MSBuild Customizations

MSBuild provides various ways to customize your build process. The following topics show how to add custom build steps, tools, and events to your MSBuild project:
