pch-use
Tells the compiler to use a precompiled header file.
Syntax
Linux and macOS: |
-pch-use filename |
Windows: |
None |
Arguments
filename |
Is the name of the precompiled header file to use. A space must appear before the file name. It can include a path. |
Default
OFF |
The compiler does not create or use precompiled headers unless you tell it to do so. |
Description
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* systems, option -pch-use is equivalent to the /Yu option.
IDE Equivalent
Alternate Options
Linux and macOS: None
Windows: /Yu
Example
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
