dereferencing pointer to incomplete type

dereferencing pointer to incomplete type

[Anshuman Singh Rawat]

Hi,
This might be the wrong question for this list, but I am giving it a shot.

I got the following error while compiling some module -

Arping.xs:153: dereferencing pointer to incomplete type
make: *** [Arping.o] Error 1


Now line 153 in the source is - 

memcpy(enet_src, src_mac->ether_addr_octet,6);

where

u_char enet_src[6] = {0x00, 0x00, 0x00, 0x00, 0x00,0x00};

struct ether_addr *src_mac;


struct ether_addr
{
    u_char  ether_addr_octet[6];
};

are the definitions.

I haven't been able to figure out what the problem is.
Can anyone help me with this ?

Thanks.
Anshuman
