WxEuphoria on ARM

Matt,

I've been using wxEuphoria on my ARM platform but I'm having trouble capturing mouse events. Since I had to cross-compile wxWidgets as well, I tried running one of the sample programs that captures mouse events and it works fine on my device. Here is the snippet of what their code looks like: 

void BombsCanvas::OnMouseEvent(wxMouseEvent& event) 
{ 
    const int gridWidth = m_game->GetWidth(); 
    const int gridHeight = m_game->GetHeight(); 
 
    wxCoord fx, fy; 
    event.GetPosition(&fx, &fy); 
....

Now looking in wxEuphoria.cpp we have the following which seems perfectly reasonable: 

object WXEUAPI  mouse_event_position(intptr_t event) 
{ 
        s1_ptr pos = NewS1(2); 
        wxMouseEvent * e = (wxMouseEvent*) event; 
        pos->base[1] = e->GetX(); 
        pos->base[2] = e->GetY(); 
        return MAKE_SEQ( pos ); 
}

But anytime my wxEuphoria progam tries to get the position of a mouse event, I get a segementation fault. GDB returns the following: 

0x4024edfc in wxMouseEvent::GetX() const () from /usr/lib/libwxeu.so.16 
0x4024edfc <_ZNK12wxMouseEvent4GetXEv+20>:    ldr   r3,   [r3, #36]

Any thoughts on what the difference could be? I see that wxEuphoria uses a different wxMouseEvent procedure than the example ( GetX() vs. GetPosition() ), but neither method works on my device.

Thanks in advance,
Ira
