SDL + OpenGL: access violation when creating buffer
I'm trying to make a window using SDL and then draw to it using GLEW and OpenGL.
so far I've made a window and initialized it with OpenGL, but when I try to create a buffer I get a wired exception.
My code looks like this:
#include <GLglew.h>
#include <SDL.h>
#include <iostream>
int main(int argc, char** argv)
{
SDL_Window* window;
SDL_Init(SDL_INIT_EVERYTHING);
//creating SDL window
window = SDL_CreateWindow("",100,100,500,400,SDL_WINDOW_OPENGL);
//setting up opengl
SDL_GL_CreateContext(window);
SDL_GL_SetAttribute(SDL_GL_DOUBLEBUFFER, 1);
glClearColor(0.6f, 0.0f, 0.0f, 1.0f);
//check if glew was initialized properly
if (glewInit() == GLEW_OK)
std::cout << "glew ok" << std::endl;
else
goto end;
////////////////////////////////////////////////I'm Getting The Error Here
GLuint bufferID;////////////////////////////////
glCreateBuffers(1,&bufferID);///////////////////
glDeleteBuffers(1,&bufferID);///////////////////
SDL_Event sdlEvent;
//event loop
while (1)
while (SDL_PollEvent(&sdlEvent))
if (sdlEvent.type == SDL_QUIT)
goto end;
end:
SDL_Quit();
return 0;
}
error: Exception thrown at 0x00000000 in opengl_project.exe: 0xC0000005: Access violation executing location 0x00000000.
the problem was that opengl was outdated (version 4.3) and glCreateBuffers is a 4.5+ feature
If you have a simular problem a solution could be updating your graphics driver or just using glGenBuffers (version 1.5+) instead.
