  1. Thank you! I didn't think that they would rename/replace that many functions.   After reading your post i searched for SDL2 beginner tutorials and found this one: http://www.opengl.org/wiki/Tutorial1:_Creating_a_Cross_Platform_OpenGL_3.2_Context_in_SDL_(C_/_SDL)   Now everything is working fine.
  2. I recently started programming an engine using SDL 1.2.15 and OpenGl. Now i tried to use Nvidia Nsight as shader debugger, but it needs a higher OpenGl version. Since SDL 1.2 doesn't support changing the OpenGl version i simply tried to use SDL 2.   I exchanged the library and include paths and changed the linker input to SDL2.lib and SDL2main.lib. (+OpenGL32.lib and glu32.lib) Now the problem is that some methods and constants of SDL are marked as undefined.   Just to check i created a new project with the code below with 2 configurations, SDL 1.2 and SDL 2. Like in the other project SDL 1.2 is working and SDL 2 not.   #include "SDL.h" #include "SDL_opengl.h" #include <stdio.h> #include <stdlib.h> #define WIDTH 800 #define HEIGHT 600 static void repaint() { glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); SDL_GL_SwapBuffers(); } static void setup_sdl() { const SDL_VideoInfo* video; int flags = 0; if ( SDL_Init(SDL_INIT_VIDEO) < 0 ) { fprintf(stderr, "Couldn't initialize SDL: %s\n", SDL_GetError()); exit(1); } atexit(SDL_Quit); video = SDL_GetVideoInfo( ); if( video == NULL ) { fprintf(stderr, "Couldn't get video information: %s\n", SDL_GetError()); exit(1); } /* Set the minimum requirements for the OpenGL window */ SDL_GL_SetAttribute(SDL_GL_RED_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_BLUE_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_ALPHA_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_DEPTH_SIZE, 16); SDL_GL_SetAttribute(SDL_GL_BUFFER_SIZE, 32); SDL_GL_SetAttribute(SDL_GL_ACCUM_RED_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_ACCUM_GREEN_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_ACCUM_BLUE_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_ACCUM_ALPHA_SIZE, 8); SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1 ); if( SDL_SetVideoMode( WIDTH, HEIGHT, video->vfmt->BitsPerPixel, SDL_OPENGL ) == 0 ) { fprintf(stderr, "Couldn't set video mode: %s\n", SDL_GetError()); exit(1); } } static void setup_opengl() { float aspect = (float)WIDTH / (float)HEIGHT; glViewport(0, 0, WIDTH, HEIGHT); glMatrixMode(GL_PROJECTION); glLoadIdentity(); gluPerspective(60.0, aspect, 0.1, 10000.0); glMatrixMode(GL_MODELVIEW); glClearColor(0, 0, 0, 0); glEnable(GL_DEPTH_TEST); glEnable(GL_CULL_FACE); glCullFace(GL_BACK); } static void main_loop() { SDL_Event event; while (1) { while( SDL_PollEvent( &event ) ) { switch( event.type ) { case SDL_QUIT: exit (0); break; } } repaint(); } } int main(int argc, char* argv[]) { setup_sdl(); setup_opengl(); main_loop(); return 0; }   Undefined items: SDL_GL_SwapBuffers SDL_VideoInfo SDL_GetVideoInfo SDL_SetVideoMode SDL_OPENGL  gluPerspective SDL_GL_SWAP_CONTROL SDL_WM_GrabInput SDL_GRAB_ON gluErrorString   I'm really clueless why some functions and constants are working and some are not.   Additional Info: I'm using Visual Studio 2010.
