Have you install the libopencl** dev dependencies?

Looks like an issue in a code gen function. It might be due to 
changes in LDC. I'll ping Guillaume.

Hello,

I don't have time at all at the moment for maintaining 
DerelictCL, can you provide a fully working PR that fix your 
problem? I will then make a git tag.

where did you get these .di files from you have in your include 
directory?

I don't think these are officially produced by the derelict-cl 
library and are the reason why your compilation is breaking. (it 
wants to evaluate some function at compile time, probably some 
CTFE or manifest constant, which fails because it only has 
definitions inside the .di file and not the function 
implementation)
