I apologise if this has been previously asked.

I am getting the following error while compiling through make: 

.../inc/intModIp.h:418: error: field 'cnc_id' has incomplete type
../inc/intModIp.h:419: error: field 'cnc_key' has incomplete type
../inc/intModIp.h:421: error: field 'fin_id' has incomplete type
../inc/intModIp.h:422: error: field 'fin_key' has incomplete type
../inc/intModIp.h:424: error: field 'remote_id' has incomplete type
../inc/intModIp.h:426: error: field 'cnc_ipsec_peer' has incomplete type
../inc/intModIp.h:427: error: field 'fin_ipsec_peer' has incomplete type
../inc/intModIp.h:428: error: field 'remote_ipsec_peer' has incomplete type
../inc/intModIp.h:430: error: field 'cnc_link' has incomplete type
../inc/intModIp.h:431: error: field 'cnc_esp' has incomplete type
../inc/intModIp.h:433: error: field 'fin_link' has incomplete type
../inc/intModIp.h:434: error: field 'fin_esp' has incomplete type

Respective code in the header file is as follows:

#if 1 || defined(SYMB_IPSEC)
    struct ipsec_state {
        int enabled;
        int active;
        int timer;
/* IPSEC_SOCKET_STATES */

        struct ipsec_id cnc_id;
        struct ipsec_priv_key cnc_key;

        struct ipsec_id fin_id;
        struct ipsec_priv_key fin_key;

        struct ipsec_id remote_id;

        struct ipsec_peer cnc_ipsec_peer;
        struct ipsec_peer fin_ipsec_peer;
        struct ipsec_peer remote_ipsec_peer;

        struct ipsec_ike_link cnc_link;
        struct ipsec_esp_sa cnc_esp;

        struct ipsec_ike_link fin_link;
        struct ipsec_esp_sa fin_esp;
    } ipsec;
#endif

could someone please help me with this. Please let me know if any other information is required.

Thanks, Sunny

问题可能是所有这些结构都是向前声明的。

标头是否包含在struct ipsec_state? 之后：

/*啊*/

struct a {
    int i;
};

/* 演示.c */

struct b {
    struct a A;
};

#include "a.h"

int main(void)
{
    return 0;
}

输出：

david@debian:~$ gcc -std=c99 -Wall -pedantic -W -Wextra -o demo demo.c
demo.c:2:11: error: field ‘A’ has incomplete type

编译器找不到声明的结构定义（ipsec_id ... ipsec_esp_sa），您可能需要包含相关的头文件

该错误的一个来源（字段类型不完整）是当您在别名（通过 typedef 定义的变量）前面使用 struct 关键字时。尝试删除 struct 关键字。

放置结构成员的指针。

struct ipsec_state {
        int enabled;
        int active;
        int timer;
/* IPSEC_SOCKET_STATES */

        struct ipsec_id *cnc_id;
        struct ipsec_priv_key *cnc_key;

        struct ipsec_id *fin_id;
        struct ipsec_priv_key *fin_key;

        struct ipsec_id *remote_id;

        struct ipsec_peer *cnc_ipsec_peer;
        struct ipsec_peer *fin_ipsec_peer;
        struct ipsec_peer *remote_ipsec_peer;

        struct ipsec_ike_link *cnc_link;
        struct ipsec_esp_sa *cnc_esp;

        struct ipsec_ike_link *fin_link;
        struct ipsec_esp_sa *fin_esp;
    } ipsec;
#endif
