segfault at creation-class after cross-compilation for Windows


I try to create a prorgam using SFML 2.0 for Windows, using a Gentoo Linux with mingw32.

I don't want to recompile SFML and all it's dependencies, so i've downloaded a compiled version from the official site (version 32 bits - SJLJ)

I have compiled my code, and executed it on wine, but it segfault when i try to instanciate a class from SFML. I have tried using static or dynamic version of SFML, nothing change.

Using debug mode, it seem that the this value is not correctly initialized on SFML classes.

my compilation flags:

CXXFLAGS = -W -Wall -ggdb3 -ISFML-2.0-rc/include -DSFML_STATIC
LDFLAGS  = -LSFML-2.0-rc/lib -static-libgcc -static-libstdc++ -mwindows      \
           -lsfml-window-s-d -lsfml-graphics-s-d -lsfml-system-s-d -lws2_32


#include <SFML/Window.hpp>

int main() {
  sf::VideoMode vm(800, 600);

  return 0;

wine error:

wine: Unhandled page fault on write access to 0x00000320 at address 0x4021e9 (thread 0026), starting debugger...

VideoMode.cpp:50 refer to the end of contructor, like with others SFML classes i've tried to use.

The this variable is not correctly initialised:

 =>0 0x004021e9 VideoMode+0x9(this=0x320, modeWidth=0x258, ...

this take the value of the first param, and all others values are shifted (fisrt arg has the second value, ...)

I've tested with severals classes with the same result.

From wich may be the problem ?
I've thought a difference between calling conventions, but i'm not sure.

It appears that you init the VideoMode for SFML in a wrong way, instead, try to create a Window object with a VideoMode as first parameter, like in the forward example :

sf::Window App(sf::VideoMode(800, 600, 32), "SFML Window");

I guess turorials should be helpful from here, but it could explain why just allocating a VideoMode from raw is causing segfault.
