+# 只做语法检查
+
+## 例子
+
+	$ cat foo.c
+	uion {
+	  char c;
+	  int i;
+	}
+	$ gcc -fsyntax-only foo.c
+	foo.c:1:6: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘{’ token
+
+## 技巧
+
+如上所示，使用`-fsyntax-only`选项可以只做语法检查，不进行实际的编译输出。
+
+详情参见[gcc手册](https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-fsyntax-only-274)
