glCreateBuffers Access Violation Exception GLFW/GLEW

Hello guys,

This issue has been adressed multiples times, but I followed every suggested solutions and nothing seems to work:

I get :

Exception thrown at 0x0000000000000000 in Program.exe: 0xC0000005: Access violation executing location 0x0000000000000000.

I already done:
-Creating a GLFW OpenGL 3.2 context with forward compatibility for the 3.0+ functionnalities to be available
-Inited in the right order GLFW > the Window context > GLEW with experimental = true

my code:

#include <stdio.h>
#include <stdlib.h>

#include <math.h>

#include "codefortress_core.h"

#include "dataparser.h"
#include "utils.h"

using namespace std;

using namespace utils;
using namespace dataparser;

	}

	// Create a rendering window with OpenGL 3.2 context

	GLFWwindow* window = glfwCreateWindow(800, 600, "OpenGL", NULL, NULL); //glfwGetPrimaryMonitor() avant dernier parama
	glfwMakeContextCurrent(window);

	if (!window)
	{

		glfwTerminate();
		exit(EXIT_FAILURE);
	}

	glfwSetKeyCallback(window, graphic_engine::key_callback);

Any help is very appreciated, thanks in advance !
(sorry for my english, and I had trouble posting, maybe I did this thread in duplicate ?)

What GPU have you?

I have a Latitude E5540 laptop with Intel® Integrated HD Graphics 4400 , It can run games of the current era, I don’t think glCreateBuffers is some kind of last generation graphics function only supported by GTi Titans …

EDIT:
I just ran glewinfo.exe and my GPU doesn’t support OpenGL 4.3+
In another forum post I found glCreateBuffers are GL 4.5, Okay it makes sense now.

So I guess I will stick with glGenBuffers for now ?

You don’t have to move to another forum. All information about OpenGL functions are on this website (khronos):

https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glCreateBuffers.xhtml

You can try to update your drivers and see if things change…

Otherwise, yes. Stick with GenBuffers.

That’s exactly the page I found, my drivers are up to date, but it’s ok, I have learned things today…

Thank you all for everything !
