typedef 结构错误：应为“;”

Question

#pragma once
typedef struct __attribute__((packed)) {
} msg_gps_time_t;

I have this code and it gives the following error: expected a ';' The code is expected to work since i got it from a 3rd party as part of a tutorial.

Answer 1

It should be:

typedef struct  {
} __attribute__((packed)) msg_gps_time_t;

The attribute has to come after the structure declaration.
