Ok, I'm trying to compile some C++ source with BlitzMax as I'm doing a little experimenting with DirectX. The C++ code compiles fine in C++ but when Imported into BlitzMax I get the error: Undefined Reference to Direct3DCreate9@4. <-- Bah No thats no a real E-Mail address...
I'm thinking this is because there's a missing Lib or something but I'm using other Direct3D commands and they aren't exibiting the same behavious. Unless it breaks the complimation at the first undefined reference. I have tried using: #pragma comment(lib, "libd3d9.a") with no luck at all.
What do I do, Im lost :( BTW Here's the code:
main.cpp
#include "d3d9.h"
struct D3DWindow
{
WNDCLASS wClass;
HINSTANCE hInstance;
};
struct D3DDevice
{
IDirect3D9 *m_Object;
IDirect3DDevice9 *m_Device;
HWND hWnd;
};
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
D3DDevice Device;
D3DWindow Window;
bool App_Run;
void iMessagePump(void)
{
MSG Msg;
while(PeekMessage(&Msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
}
void iCleanup(void)
{
if(Device.m_Device)
Device.m_Device->Release();
if(Device.m_Object)
Device.m_Object->Release();
if(Device.hWnd)
DestroyWindow(Device.hWnd);
}
void iGraphics3D(int Width, int Height, int Depth, int Fullscreen)
{
DWORD Style;
if(Fullscreen)
Style = WS_POPUP | WS_VISIBLE;
else
Style = WS_OVERLAPPED | WS_SYSMENU | WS_VISIBLE;
Window.hInstance = GetModuleHandle(0);
Window.wClass.style = CS_OWNDC;
Window.wClass.cbClsExtra = 0;
Window.wClass.cbWndExtra = 0;
Window.wClass.hInstance = Window.hInstance;
Window.wClass.hIcon = LoadIcon(NULL,IDI_APPLICATION);
Window.wClass.hCursor = LoadCursor(NULL,IDC_ARROW);
Window.wClass.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH);
Window.wClass.lpszMenuName = NULL;
Window.wClass.lpszClassName = "Engine";
Window.wClass.lpfnWndProc = WndProc;
RegisterClass(&Window.wClass);
Device.m_Object = Direct3DCreate9(D3D_SDK_VERSION);
Device.hWnd = CreateWindow("Engine", "Test", Style, 150, 150, Width, Height, NULL, NULL, Window.hInstance, NULL);
D3DPRESENT_PARAMETERS dParam;
ZeroMemory(&dParam, sizeof(dParam));
dParam.BackBufferCount = 1;
dParam.MultiSampleType = D3DMULTISAMPLE_NONE;
dParam.MultiSampleQuality = 0;
dParam.SwapEffect = D3DSWAPEFFECT_DISCARD;
dParam.Flags = 0;
dParam.hDeviceWindow = Device.hWnd;

dParam.EnableAutoDepthStencil = false;
if(Fullscreen)
{
dParam.BackBufferWidth = Width;
dParam.BackBufferHeight = Height;
dParam.Windowed = false;
ShowCursor(false);
}
else
dParam.Windowed = true;
Device.m_Object->CreateDevice(D3DADAPTER_DEFAULT, D3DDEVTYPE_HAL, Device.hWnd, D3DCREATE_HARDWARE_VERTEXPROCESSING, &dParam, &Device.m_Device);
App_Run = true;
if(Device.m_Object = NULL)
App_Run = false;
if(Device.m_Device == NULL)
App_Run = false;
}
void iRenderWorld()
{
Device.m_Device->Clear(0, NULL, D3DCLEAR_TARGET, 0x00000000, 1.0, 0);
Device.m_Device->BeginScene();
Device.m_Device->EndScene();
}
void iFlip(bool VWait = true)
{
Device.m_Device->Present(NULL, NULL, NULL, NULL);
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT Message, WPARAM wParam, LPARAM lParam)
{
switch(Message)
{
case WM_PAINT:
break;
case WM_DESTROY:
App_Run = false;
break;
case WM_KEYDOWN:
App_Run = false;
break;
}
return DefWindowProc(hWnd, Message, wParam, lParam);
}
test.bmx
Import "main.cpp"
Extern
Function iGraphics3D(Width, Height, Depth, Fullscreen)
Function iMessagePump()
Function iCleanup()
Function iRenderWorld()
Function iFlip(VSync:Int)
End Extern
iGraphics3D(800, 600, 32, 0)
I'm also getting another error: undefined reference to `iGraphics3D' but Im assuming thats because its failing to link the Direct3DCreate9 function.
Also, Here are the libraries I am using. They are a Direct convert from the Visual Studio lib style library format into MinGW compatible .a format.
Thanks in Advance.
