structure inside structure - c++ Error
- by gamadeus
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
