How to display My Current System IP Address...???

[maveric]

Hi.. All,

I am developing an application in which i need to communicate with and transmit data using TCP protocol...
For that i need IP Address...
So my question is how to get my Ip address...
i tried using this....
QHostAddress ( quint32 ip4Addr ) for getting... Ip address of my system...

but it returned some linker error...

These are the linker errors... (which i couldnt debug them...)

rfswitchmainwindow.obj : error LNK2019: unresolved external symbol "__declspec (dllimport) public: __thiscall QHostAddress::QHostAddress(class QHostAddress const &) " (__imp_??0QHostAddress@@QAE@ABV0@@Z) referenced in function "private: void __thiscall QList<class QHostAddress>::node_copy(struct QList<class QHostAddress>::Node *,struct QList<class QHostAddress>::Node *,struct QList<class QHostAddress>::Node*) " (?node_copy@?$QList@VQHostAddress@@@@AAEXPAUNode@1 @00@Z)

so can any one tell me where i am going wrong...?
