Yeah its a wrapper for OpenCL so as long as the names and 
signatures of the symbols match it should work.

"green team guy"?

It that with the OpenCL C compiler? DCompute goes through SPIR-V 
for OpenCL (although it would be nice to support SPIR. 
Unfortunately the official version SPIR 2.0 is based of is not 
supported by LDC), I dont know if this makes a difference.
It would be nice to eventually support AMDGCN et. al. at some 
point but I don't have the time at the moment.
