I'am trying to play a bit with D and OpenGL by using the available Derelict bindings, but i'am even failing to create a window.

At the moment my code is as simple as:
-----------------------------------------
import derelict.glfw3.glfw3;

import std.c.stdio : fputs, fputc, stderr;

extern(C) nothrow void glfwPrintError(int error, const(char)* description) {
    fputs(description, stderr);
    fputc('\n', stderr);
}

void main() {
    DerelictGLFW3.load();

    glfwSetErrorCallback(&glfwPrintError);

    if(!glfwInit()) {
        glfwTerminate();
        throw new Exception("Failed to create glcontext");
    }
}
------------------------------------------

When i try to run it using dub i get the following:
{ test }  » dub run                                                                                                                                                                                                   /c/git/opengl/test 2

If i leave only the line DerelictGLFW3.load() it doesn't crashes.

I'am running windows 10 x64 and and dmd says: DMD32 D Compiler v2.068.0

Anyone has an idea of might be going on?

Thanks,

The problem was in me using the 64bit version of the GLFW dll. DMD doesn't support compiling to x64? I tried using the DUB flag --arch=x86_x64 but i then got an error saying:
Can't run '\bin\link.exe', check PATH

What would be the correct way to compile to x64?

Thanks,

To compile 64-bit programs on Windows, DMD requires the Microsoft toolchain. The easiest thing to do is to install the Community Edition of Visual Studio 2013 (DMD isn't yet compatible with VS 2015).

Also, you aren't using OpenGL in this example, but GLFW :)

Don't forget to check your sc.ini file after that, and uncomment the relevant lines.
