本文分析了使用GCC编译C语言程序时遇到的一个常见错误：忘记在结构体定义末尾添加分号导致的编译失败。通过具体的例子，详细解释了如何定位问题并修复。

C语言编译 gcc -c my_struct.c 报错：my_struct.c:3:1: 错误：expected ‘;’, identifier or ‘(’ before ‘int’ int mai

原因：是因为我在头文件订单struct student {}的时候忘记在最后加;分号了

c/c++: 编译错误：error: expected expression before ‘)‘ token & expected ‘；‘, ‘,‘ or ‘)‘ before ‘=‘ token

error: expected expression before ‘)’ token 含义：在括号前期望一个表达式，意味着目前括号去没有表达式。可能的原因是函数调用，在最后的括号前多了一个逗号。 578 …/route.c: In function ‘routes’: 579 /home/sb/log.h:198:35: error: expected expression before ‘)’ token, 在这里函数：log_print是一个可以接收可变参数的一个函数； 580 log_pri

今天我在写程序的时候出现了这个问题，就是在mmu.c里面的每一个函数入口行数都会报这个错，然后我仔细检查了每一行的符号是不是缺分号，还是缺逗号，各种方法找了半小时。。。。。 最后发现是在头文件声明的时候没有加分号而导致的 总结一下，这个错误一般是符号错误，编译器一般都可以定义到你需要的那一行，但是当出现多行的时候，你就需要检查一下头文件了 ...

我们遇到了编译错误，主要问题在于： 1. 重复定义了 `IFNAMSIZ` 和 `struct ifreq`，因为系统头文件 `<net/if.h>` 已经定义了它们。 2. 在定义 `struct ifreq` 时，结构体内部的成员命名与系统头文件中的不一致。 3....

今天早上在编译工程的时候，总是会报出expected identifier or ‘(’ before***的错误，查看了代码没有任何问题，后来又在网上找原因受到启发，原来是我的代码里有未被识别的字符，将那段字符注释掉就可以了，还好是小问题，写出来记录下自己曾经踩过的坑，防止再次出错。

在工作中，有时候需要编译现有的代码，在经过千难万险调试后编译，会出现恼人的 expected identifier before ‘(’ token提示。 比如在一个枚举类型中，会告诉你某行有这种错误。这是相当让人摸不到头脑的。 又或者，在一个宏定义语句中出现这种错误。 一般来说，出现这种情况，是语句中有些定义的名字发生了冲突。简单的就是改名处理。   如果确定是宏定义的名称冲突了，有
