How Can I Build Faster? 

This topic contains tips for reducing the amount of time it takes to build a project.

• Reduce the number of header files Visual C++ must include and check for every build.

• Use precompiled headers. See /Y (Precompiled Headers) for more information.

• When calling cl.exe directly, do not invoke the compiler once for every source file; pass all source files to cl.exe in the same invocation to create .obj files.

• Use minimal rebuild; see /Gm for more information.

• Use incremental linking; see /INCREMENTAL for more information.

• Use #pragma once, when appropriate. For example, if your headers use include guards.

• Dynamically link to the CRT; see /MD for more information.

Additional topics include:

• Faster Builds and Smaller Header Files

• Excluding Files When Dependency Checking
