Field has incomplete type error

In my C-code I've got a tcpsock.c and tcpsock.h file. The tpcsock.c file include's the tcpsock.h file. This socketcode is used in a connmgr.c (which includes tcpsock.c). In the C file I've got two structs, which are defined as follows:

struct tcpsock{
   long cookie;
   int sd;
   char * ip_addr;
   int port;
};

struct conn{
   struct tcpsock_t socket;
   long last_active;
};

In the header file I have the following code:

typedef struct tcpsock tcpsock_t;
typedef struct conn conn_t;

When I try to compile this, I'm getting the following error:

In file included from connmgr.c:12:0:
lib/tcpsock.c:78:22: error: field ‘socket’ has incomplete type
struct tcpsock_t socket;
                 ^

I've been searching everywhere but wasn't able to find a solution, so I hope anyone here can help me. Thanks in advance!

typedef struct tcpsock tcpsock_t; defines tcpsock_t as a struct tcpsock. Hence, your struct definition must look like this:

struct conn{
   tcpsock_t socket;
   long last_active;
};
