Hi,

I am sure this has been asked a thousand times before, but can anyone link me to a tutorial on how to set up derelict and GLFW3, I am trying to work on a project and I just can't get it set up regardless of how many times I read the derelict readme's.

Also, if anyone knows of any good tutorials or ways of creating a flow-graph editor similar to blender's flow-graph editor interface I would greatly appreciate a link or some assistance, I have a rather large project I am working on which I would love to do in D and requires a flow-graph GUI much like blender's.

Cheers!

See the Derelict documentation (linked from the README) on using Derelict with DUB-managed projects [1]. Summary:

Step 1: Make sure the GLFW 3 library is installed on your system. On Windows, that means you just put the glfw3.dll in the same directory in which your executable will reside. On Mac, it's easiest to install with Homebrew (should be 'brew install glfw' or 'brew install glfw3', can't recall which). On Linux, use your package manager. Get the dev version of the package if you want, but you don't need it with Derelict.

Step 2: Add 'derelict-glfw3' as a dependency to your dub.json or dub.sdl file (assuming you are using dub to manage your project. If not, see the Derelict documentation using Derelict packages with non-DUB projects [2]).

For dub.json:
"dependencies" : {
"derelict-glfw3": "~>3.1.1"
}

For dub.sdl:

dependency "derelict-glfw3" version="~>3.1.1"

Step 3: Import derelict.glfw3.glfw3 and somewhere in your code, preferably during startup, call DerelictGLFW3.load.

```
import derelict.glfw3.glfw3;
void main() { DerelictGLFW3.load(); }
```

I have done as you have said here, I have glfw3.dll into the same directory as the executable, and included the dependencies in the dub.json file, however when I run my intialization code, it gives me the following error:

derelict.util.exception.SharedLibLoadException@src\derelict-util\source\derelict\util\exception.d(35): Failed to load one or more shared libraries:

The code I have that runs derelictGLFW3.load() etc is as follows:

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

int main()
{
	DerelictGL3.load();
	DerelictGLFW3.load();
	
	GLFWwindow* window;
	
	if(!glfwInit())
	{
		return -1;
	}
	
	window = glfwCreateWindow(1280,720, "D OpenGL Engine", null, null);
	if(!window)
	{
		glfwTerminate();
		return -1;
	}
	
	/* make window' context current */
	glfwMakeContextCurrent(window);
	DerelictGL3.reload();
	
	while(!glfwWindowShouldClose(window))
	{
		glfwSwapBuffers(window);
		glfwPollEvents();
	}
	
	glfwTerminate();
	return 0;
}

OK, this has nothing to do with your code or with Derelict. When you get a SharedLibLoadException, the message it contains comes from the system. In this case, it's the bit that says 'Access is denied'. I've never encountered that while loading libraries on Windows. It looks like something to do with file permissions, but I really have no idea. You'll need to consult Google to find out what it means to get that message in conjunction with LoadLibrary (which is what Derelict is using internally).

Actually, I think I may know the problem with the access denied bit, it's too late for me to test now but I will test tomorrow.  My D source code and the GLFW3.dll library are stored on a Linux file server (I am using D in Eclipse on a Windows 10 machine), so perhaps there is some issue with the FileServer denying access to certain things, so I will investigate if moving the source and the dll to my local machine will remove this issue, I will post here the results.

Do DLLs have to be marked executable? I seem to recall something like that.

Okay, so I moved my source code and the glfw3 dll to my local machine and lo and behold it worked, so I gather the 'access denied' problem I was having before was an issue regarding permissions on the FileServer side.  I should probably make note of that somewhere...
