Manually specifying the filename and location of a PreCompiled Header (PCH) file

To manually specify the filename and location of a PCH file, use any of the following compiler command-line options:

  • --create_pch=filename

  • --pch_dir=directory

  • --use_pch=filename

If you use --create_pch or --use_pch with the --pch_dir option, the indicated filename is appended to the directory name, unless the filename is an absolute path name.

Note

If multiple options are specified on the same command line, the following rules apply:

  • --use_pch takes precedence over --pch

  • --create_pch takes precedence over all other PCH file options.
