SYMPTOMS
If you move a project from the Intel platform to the Alpha RISC platform and attempt to add a new Alpha configuration (for example, by selecting Build|Configurations...|Add... from the Developer Studio menu) Developer Studio does not provide an option to choose "Win32(Alpha)" in the platform combo box.



CAUSE
Visual C++ RISC Edition is not a cross-development environment, but rather a native-development environment and is, therefore, not presented as a unique configuration platform. Additional platforms are only available in the Platforms combo box if they produce code that runs on a platform other than the native environment. Examples of this are the Visual C++ development environments for Apple Macintosh and Windows CE. These platform types must be built on the Intel platform, but they produce code that only runs on their respective platform architectures.



RESOLUTION
In native Visual C++ development environments, simply add a "Win32" platform and use the configuration name to identify the platform. For example, you might use the names "AlphaRelease" and "AlphaDebug" on the Alpha platform.



MORE INFORMATION
Under Visual C++ version 4.0 RISC Edition, the Win32 platform name is displayed as "Win32 (platform)". For example, "Win32 (MIPS)", "Win32 (ALPHA)", etc.

The Visual C++ 5.0 documentation incorrectly implies that the platforms will be presented in a similar manner.

An existing 4.x project that contains the Win32 (platform) form of the configuration name will retain this name when migrated to Visual C++ version 5.0.
