Getting Started

To use DCompute you need DCompute (obviously) and a modified ldc (available here). In addition to its normal dependencies, to build the modified ldc you'll need Khronos's SPIRV-LLVM (available here. To build ldc follow its build guide, but note that you may need to force the linking of libLLVMSPIRVLib.a by modifying the makefile by inserting -L-lLLVMSPIRVLib into the (l|g)dmd invocation around line 140 of build.make. Adapt the previous to your favourite build environment/OS.

If at any point you think ldc is doing something funky: use the -output-ll (output llvm ir) switch in combination with the -vv (enable logging) flag to see whats going on. grep is also useful a -vv produces a lot of output.
