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: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
