Visual Studio 2005
This topic describes how to set up C++ applications to target 64-bit platforms using project configurations available in the Visual Studio Integrated Development Environment (IDE).
To develop 64-bit applications you must install one or both of the Visual C++ 64-bit compilers, otherwise 64-bit project configurations will not be available in the IDE. See Installing Visual Studio 64-bit Components for information.
Note |
64-bit tools are not available on Visual C++ Express Edition by default. To enable 64-bit tools on Visual C++ Express Edition, install the .NET Framework SDK in addition to Visual C++ Express Edition. Otherwise, an error occurs when you attempt to configure a project to target a 64-bit platform using Visual C++ Express Edition. |
The first procedure describes how to change the active project configuration to target 64-bit platforms using the Visual Studio IDE. The second procedure describes how to migrate Win32 project settings into a 64-bit project configuration.
To set up C++ applications to target 64-bit platforms
- Open the C++ project that you want to configure to target a 64-bit platform.
- Open the property pages for that project. For more information, see How to: Open Project Property Pages.
Note |
For .NET projects, make sure the Configuration Properties node, or one of its child nodes, is selected in the <Projectname> Property Pages dialog box. Otherwise, the Configuration Manager button remains disabled. |
- Click Configuration Manager to open the Configuration Manager Dialog Box.
- Click the Active Solution Platform list, and then select the <New…> option to open the New Solution Platform Dialog Box.
- Click the Type or select the new platform drop-down arrow, and then select a 64-bit platform.
Note |
In the New Solution Platform dialog box, you can copy existing project settings into the new 64-bit project configuration using the Copy settings from option. |
- Click OK. The platform you selected in the preceding step will appear under Active Solution Platform in the Configuration Manager dialog box.
- Click Close in the Configuration Manager dialog box, and then click OK in the <Projectname> Property Pages dialog box.
To copy Win32 project settings into a 64-bit project configuration
- When the New Solution Platform dialog box is open while you set up your project to target a 64-bit platform, click the Copy settings from drop-down arrow, and then select Win32. The following project settings are automatically updated on the project level:
- /MACHINE (Specify Target Platform) is set to /MACHINE:IA64 or /MACHINE:X64.
- Register Output is turned OFF. For more information, see Linker Property Pages.
- Target Environment is set to /env x64 or /env ia64. For more information, see MIDL Property Pages: General.
- Validate Parameters is cleared and reset to the default value. For more information, see MIDL Property Pages: Advanced.
- If Debug Information Format was set to /ZI in the Win32 project configuration, then it is set to /Zi in the 64-bit project configuration. For more information, see /Z7, /Zi, /ZI (Debug Information Format).
- Values of WIN32 are replaced by WIN64 for /D (Preprocessor Definitions).
Note |
None of these project properties are changed if they are overridden on the file level. |
