14行最后的；应该改为，号吧

[booirror]

这个错误很明显啊 4个警告，1个错误 showtty.c:14:24: error: expected ‘}’ before ‘;’ token 表示14行第24字符有错 你回头看看，这里确实不应该是";"号，而应该是","

[worldy]

#include <stdio.h> #include <termios.h> #include <stdlib.h> #include <unistd.h> struct flaginfo { int fl_value; char* fl_name; }; struct flaginfo local_flags[]= { {ISIG, "Enble signal"},//每个数据单元必须使用大括号 {ICANON, "Cannonical input (erase and kill)"}, {ECHO, "Enable echo"}; {ECHOE, "Echo ERASE as BS-SPACE-BS"}, {ECHOK, "Echo KILL by starting new line"}, {0, NULL} }; ....

[worldy]

另外， {ECHO, "Enable echo"}; 后面应该是,

[To_be_sky]

这个应该应该蛮简单的，看错误信息就知道了； showtty.c:14:24: error: expected ‘}’ before ‘;’ token 很明显应该是“，”。

[yulitingfeng]

呵 呵。。。

[光流溢彩]

 {ECHO, "Enable echo"};

如果;是你要的内容的话  需要写成  {ECHO, "Enable echo"}\;

引用 3 楼 worldy 的回复:

#include <stdio.h> #include <termios.h> #include <stdlib.h> #include <unistd.h> struct flaginfo { int fl_value; char* fl_name; }; struct flaginfo local_flags[]= { {ISIG, "Enble signal"},//每个数据单元必须使用大括号 {ICANON, "Cannonical input (erase and kill)"}, {ECHO, "Enable echo"}; {ECHOE, "Echo ERASE as BS-SPACE-BS"}, {ECHOK, "Echo KILL by starting new line"}, {0, NULL} }; ....

原来是这问题，那个分号错误不是主要问题
