void main(){

	DerelictGL3.reload();
 //DerelictSDL2.load();



 writeln("Fred is nigh on impossible to

configure");

}

this is all the code I have, and I get an object.Error@(0): Access Violation.
I have looked all over the internet and I am unable to find a fix for this.
Any ideas on how to fix this or what is the cause?

When you activate an OpenGL context you reload it. You do not do this when one is not activated.

import derelict.opengl3.gl3;
import derelict.glfw3.glfw3;

import buffer, shader;

pragma(lib, "DerelictGLFW3");
pragma(lib, "DerelictGL3");
pragma(lib, "DerelictUtil");
pragma(lib, "dl");

int main()
{
	DerelictGL3.load();
	DerelictGLFW3.load();
    GLFWwindow* window;


    if (!glfwInit())
        return -1;


    window = glfwCreateWindow(640, 480, "Hello World", null, null);
    if (!window)
    {
        glfwTerminate();
        return -1;
    }

    /* Make the window's context current */
    glfwMakeContextCurrent(window);
	DerelictGL3.reload();


    while (!glfwWindowShouldClose(window))
    {



        glfwSwapBuffers(window);


        glfwPollEvents();
    }

    glfwTerminate();
    return 0;
}

Ah ok!
so here's my updated code. I still get the object error. I am trying to get a  blank window to appear. I call the reload after I set the glfwcontext. I'm not sure what I'm missing here.

the Error@(0) is almost always a null pointer dereference. Why that would be occurring for just attempting to load the libs i'm not sure.

Doing so shouldn't cause an access violation, though. It would be throwing a DerelictException saying that no context has been loaded yet.

There's nothing obvious that jumps out. You really should not have been seeing an access violation with the first bit of code you posted if the problem were simply that no context were loaded. I suggest you try again with just a simple call to DerelictGL3.load and see if you still get the error. If so, see if you can run a hello world.

I meant to say, failure to do so.

I managed to get it working. I couldn't do a writeln command because I was getting that same error. I created a new project and that fixed the problem. :) thanks for the help!
