Description
This option tells the compiler where to find or create a file (PCH) for precompiled headers.
This option can be used with the -pch, -pch-create, and -pch-use options.
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 -pch-dir /pch source32.cpp
It produces the following output:
"source32.cpp": creating precompiled header file /pch/source32.pchi
