Hi,

I'm interested in updating the existing OpenCL bindings 
(https://github.com/Trass3r/cl4d) so they work with Derelict3, 
but have never undertaken such a task.
I'm not sure where/how to begin.

Does anyone have any advice? :)

Trass3r's binding is static, with a wrapper on top of it. Plus, 
the binding (in the 'c' package) uses mixins to some end (just 
gave it a cursory look, so not clear on the details). I don't 
think there's anything to "update" here. It's a different 
approach entirely than what I take with Derelict.

My advice is just to start from scratch. Look at the smaller 
Derelict packages (DerelictAL, DerelictFT, DerelictGLFW3) for the 
basic layout. I'm not familiar with the OpenCL API. Never used it 
or looked at it, so I don't know if you'll need something as more 
complex like the DerelictGL3 package. But the basic idea is to 
put all type declarations in one module named types.d, all 
function pointer alias and declarations in functions.d, and then 
load everything up via a subclass of SharedLibLoader in a module 
named appropriately for the binding (in this case, cl.d would be 
a good choice, with derelict.opencl as the package name).

This is actually something I've wanted to get around to for a 
long time. I'm busier than ever these days so I can't take it on 
right now for sure. If you do decide to get busy on it, drop by 
the Derelict forums[1] if you need any help. You could email me, 
too, but I imagine that any advice I give you could be useful for 
others wanting to work on a Derelictified binding.

That's a shame.

I see. That's a larger project than I'd hoped. Considering I've 
never created a binding before, is there some kind of 
tutorial/recommended reading available?

There's a page at dlang.org[1], and I have a series of 5 blog 
posts on the topic over at gamedev.net, starting with part 1[2].

You're missing dstep. Using dstep I converted some c-libraries in 
short time. It's quite easy to use and usually just some minor 
modification are needed to  adjust auto-generated d interface.
