Hi,

I've got a little issue porting my app (Qt4.1) under window.
All works fine while I'm compiling under linux (gcc4 ; kdevelop ; qt 4.1) but I've got compilation error trying to compile the SAME sources under windows (g++, Qt 4.1).

The error seems to be coming while the linking phase, and only for QTcpSocket class :

I've got that kind of g++ command :

Any idea ?
