| OFF | The compiler does not create or use precompiled headers unless you tell it to do so. |
This option tells the compiler where to find or create a file (PCH) for precompiled headers.
This option can be used with the -pch, -create_pch, and -use-pch 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.
None
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
