First of all the error I am getting is of the type:

Request for member 's' of struct1.struct1::struct2, which is of non class type '__u32'

where:

struct struct1 {

struct x struct2;
struct x struct3;
struct x struct4;
};

The usage is of the form:

struct struct1 st1;
st1.struct2.s = Value;

Now my struct1 is:

struct ip_mreq_source {
  struct in_addr imr_multiaddr;
  struct in_addr imr_sourceaddr;
  struct in_addr imr_interface;
};

struct 'x' is in_addr Where:

typedef uint32_t in_addr_t;
struct in_addr
  {
    in_addr_t s_addr;
  };

element 's' is the element s_addr in in_addr.

My detailed error coming out of g++ (GCC 4.4.3) from the Android based compiler:

I am not sure what is causing the error. Any pointers would be great - no pun intended. Thanks
