Hi All I have been studying c++ for over a year now and have decided to dable a bit in the games side of things, I have bought a book call GAME PROGRAMMING IN C++: START TO FINISH, by Erik Yuzwa. It is an asteriod game. I have tried to run a sample program on my computer that uses SDL see below. I have linked up the peon engine that I am using to my compiler (VC2008) and the SDL also but this error occurs: 1>MSVCRTD.lib(cinitexe.obj) : warning LNK4098: defaultlib 'msvcrt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library Do you have any ideas on how I can solve this. /** * This source code is part of the samples for "Game Programming in C++: Start to Finish". * * This example SDL code will load up a bitmap image of the SDL logo, and just display * it in a window for you. It's very bare bones. * * @Author : Erik Yuzwa * @Date : 09/01/2005 * @Version: 1.0 */ #include <SDL.h> int main(int argc, char* argv[]) { //initialize SDL and the video subsystem if(SDL_Init( SDL_INIT_VIDEO ) < 0) return -1; //create an SDL_Surface object which represents the //game window SDL_Surface* screen = SDL_SetVideoMode(640, 480, 0, 0); //signal SDL to change the text of the main window //to "Hello World" SDL_WM_SetCaption("Hello World", "Hello World"); //load the SDL logo bitmap to a temporary surface SDL_Surface* temp = SDL_LoadBMP("data\\textures\\sdl_logo.bmp"); //create the working SDL_Surface which matches the //display format of the temporary surface SDL_Surface* bg = SDL_DisplayFormat(temp); //free the memory allocated to the temporary SDL_Surface SDL_FreeSurface(temp); SDL_Event event; bool quit = false; //This is the main message loop of the game while(!quit) { //check the message queue for an event if (SDL_PollEvent(&event)) { //if an event was found switch (event.type) { //check to see if the window was closed via the "x button" case SDL_QUIT: //set the quit flag to true quit = true; break; //check the keyboard to see if the ESC key was pressed case SDL_KEYDOWN: switch (event.key.keysym.sym) { case SDLK_ESCAPE: //set our quit flag to true quit = true; break; } break; } } //draw the background sprite SDL_BlitSurface(bg, NULL, screen, NULL); //update the current window SDL_UpdateRect(screen, 0, 0, 0, 0); } //free the allocated memory for the background surface SDL_FreeSurface(bg); //quit SDL and allow it to clean up everything SDL_Quit(); //return control to Windows with no errors return 0; } PS: I have encountered a number of errors trying to run this simple program and have managed to solve them all but this one I am stumped. Vista what I am using wasn't out when the book was published in 2005 but there is a mention of it and the author was aware if this helps.
