Hi Guys.
This is a bit of a newbiee question, but ive googled for ages and still no luck. When I comile all my souce files it works fine, its when I link it that it stuffs up. It comes up with these errors.
The trouble is that I've tried almost everything. Dont know how to use DUMPBIN, ive triedCode:winmain.obj : error LNK2001: unresolved external symbol "void __fastcall Game_Run(struct HWND__ *)" (?Game_Run@@YIXPAUHWND__@@@Z) winmain.obj : error LNK2001: unresolved external symbol "int __fastcall Game_Init(struct HWND__ *)" (?Game_Init@@YIHPAUHWND__@@@Z) Debug/Trans_Sprite.exe : fatal error LNK1120: 2 unresolved externals Error executing link.exe.etc but it wont workCode:extern "C" ...
Heres my code
And the header file that has the prototypes for those functionsCode:// Beging Game Programing // Chapter 7 // winmain.cpp -- windows code framework // header files #include <d3d9.h> #include <d3dx9.h> #include <time.h> #include <stdio.h> #include "dxgraphics.h" #include "game.h" //windows event call back function LRESULT WINAPI WinProc( HWND hWnd, UINT msg, WPARAM wParam, LPARAM lParam ) { switch ( msg ) { case WM_DESTROY: //release the direct 3d device if (d3ddev != NULL) d3ddev->Release(); //release the direct 3d object if (d3d != NULL) d3d->Release(); //call the 'front end' shut-down function Game_End(hWnd); // tell windows to kill this program PostQuitMessage(0); return 0; } return DefWindowProc (hWnd, msg, wParam, lParam); } //helper function to set up the window properties ATOM MyRegisterClass(HINSTANCE hInstance) { //create the window class structure WNDCLASSEX wc; wc.cbSize = sizeof(WNDCLASSEX); //fill the struct with info wc.style = CS_HREDRAW | CS_VREDRAW; wc.lpfnWndProc = (WNDPROC)WinProc; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hInstance = hInstance; wc.hIcon = NULL; wc.hCursor = LoadCursor(NULL, IDC_ARROW); wc.hbrBackground = (HBRUSH)GetStockObject(BLACK_BRUSH); wc.lpszMenuName = NULL; wc.lpszClassName = APPTITLE; wc.hIconSm = NULL; //set up the window with the class info return RegisterClassEx(&wc); } //entry point for a windows program int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { MSG msg; HWND hWnd; //Register the class MyRegisterClass(hInstance); //set up the screen in windowed or full-screen mode?
