Description
This option lets you use a specific 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.
Caution
Depending on how you organize the header files listed in your sources, this option may increase compile times. To learn how to optimize compile times using the PCH options, see "Precompiled Header Files" in the User's Guide.
Alternate Options
None
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
