Set the preprocessor options for your build configuration
Option | Description |
---|---|
Do not search system directories (-nostdinc) | Do not search the standard system directories for header files. Only the directories you have specified with -I options (and the directory of the current file, if appropriate) are searched. |
Preprocess only (-E) | Stop after the preprocessing stage; do not run the compiler proper. The output is in the form of preprocessed source code, which is sent to the standard output. Input files that don’t require preprocessing are ignored. |
Defined symbols (-D) | Predefine macro |
Undefined symbols (-U) | Cancel any previous definition of macro, either built in or provided with a -D option. |
