Tells the compiler to check only for correct syntax.

## Syntax

Linux: | -syntax-only

macOS: | -syntax-only

Windows: | /syntax-only

## Arguments

None

## Default

OFF | Normal compilation is performed.

## Description

This option tells the compiler to check only for correct syntax. It lets you do a quick syntax check of your source file.

Compilation stops after the source file has been parsed. No code is generated, no object file is produced, and some error checking done by the optimizer is bypassed.

Warnings and messages appear on stderr.

## IDE Equivalent

None

## Alternate Options

Linux: -y, -fsyntax-only, -syntax (this is a deprecated option)

macOS: -y, -fsyntax-only

Windows: /Zs
