Hi everybody, I'm new to game / graphics programming and have started to dabble with SDL and OpenGL. So to start off with a very simple program I'm trying to load a BMP with SDL_LoadBMP (windows with Visual Studio 2008) I'm includiing the full source here (very short :) ) #include <sdl/sdl.h> #include <stdio.h> SDL_Surface* screen = NULL; SDL_Surface* img = NULL; SDL_Event myevent; bool quit=false; int main(int argc, char *argv[]) { atexit(SDL_Quit); if (SDL_Init(SDL_INIT_VIDEO) == -1) {printf("SDL init failed"); exit(1);} img = SDL_LoadBMP("woods.bmp"); //simple 640x480x24bpp bmp if (!img) { printf("Couldn't load bmp \n",SDL_GetError()); exit(1); }; //and just here my prgram crashes with "couldn't load bmp" SDL_GL_SetAttribute( SDL_GL_DOUBLEBUFFER, 1 ); screen = SDL_SetVideoMode(1024,768,32,SDL_OPENGL | SDL_FULLSCREEN); if (screen == NULL) {fprintf(stderr,"Video mode failed"); exit(1); } while (!quit) { SDL_PollEvent(&myevent); switch (myevent.type) {case SDL_KEYDOWN: switch (myevent.key.keysym.sym) {case SDLK_ESCAPE : quit = true; break; }; break; }; }; SDL_FreeSurface(img); SDL_Quit(); }

Try using the SDL 'get error' function to determine what exactly went wrong (it may just be that you don't have the file in the right location).

Also, use [source][/source] tags when posting code.

The most probable reason is that the program can't find the bitmap file.

Remember that Visual Studio's debugger, by default, starts the application in the same path as the project file, not under the debug or release folder. Of course, you can change that in project's settings.

Of course, you can also try to run the executable from outside Visual Studio. Then you should place the executable and the bitmap in the same folder.
