pch-use

Tells the compiler to use a precompiled header file.

Syntax

Linux OS and OS X:

-pch-use filename

Windows OS:

None

filename

Is the name of the precompiled header file to use. A space must appear before the file name. It can include a path.

OFF	The compiler does not create or use precompiled headers unless you tell it to do so.

This option tells the compiler to use a precompiled header (PCH) file.

It is supported for multiple source files when all source files use the same .pchi file.

This option cannot be used in the same compilation as the -pch-create option.

To learn how to optimize compile times using the PCH options, see "Using Precompiled Header Files" in the User's Guide.

On Windows* OS*, option -pch-use is equivalent to the /Yu option.

None

Linux and OS X: None

Windows: /Yu

Consider the following command line:

icpc -pch-use /pch/source32.pchi source.cpp

It produces the following output:

"source.cpp": using precompiled header file /pch/source32.pchi
