VCCLCompilerTool Interface

  • Article

The VCCLCompilerTool object exposes the functionality of the C++ compiler options. See Compiler Options for more information about compiler options.

Namespace:  Microsoft.VisualStudio.VCProjectEngine
Assembly:  Microsoft.VisualStudio.VCProjectEngine (in Microsoft.VisualStudio.VCProjectEngine.dll)

Remarks

The following new compiler options were added in Visual Studio 2005:

The following compiler options were removed in Visual Studio 2005:

  • /Op

  • /G6, /G7, and /GB

Examples

The following example demonstrates how to use the EnablePREfast and AdditionalOptions properties to set the /analyze:WX- switch. (Both properties are required to do this.) Specifying /analyze:WX- means that code analysis warnings will not be treated as errors when compiling with /WX. For more information, see /analyze (Enterprise Code Analysis).

To run this example, enter and run this example as outlined in How to: Compile and Run the Automation Object Model Code Examples. Then, in the new instance of Visual Studio, load a Visual C++ project and use the Add-in Manager to activate the add-in.
