Tells the compiler to create a precompiled header file.

Syntax

Linux:
None
macOS:
None
Windows:
/Yc
[
filename
]
Arguments
filename
Is the name of a C/C++ header file, which is included in the source file using an #include preprocessor directive.
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 create a precompiled header (PCH) file. It is supported only for single source file compilations.
When
filename
is specified, the compiler creates a precompiled header file from the headers in the C/C++ program up to and including the C/C++ header specified.
If you do not specify
filename
, the compiler compiles all code up to the end of the source file, or to the point in the source file where a hdrstop occurs. The default name for the resulting file is the name of the source file with extension .pchi.
This option cannot be used in the same compilation as the
/Yu
option.
On Linux* and
macOS*
, option
/Yc
is equivalent to the
-pch-create
option.
Alternate Options
Linux and
macOS*
:
-pch-create
