Hi,

I have a cuda kernel already working in my cpp project(https://github.com/kerdemdemir/CUDABeamformer/blob/master/CudaBeamformer/kernel.cu)

I am trying to convert this to D with using DCompute. I already compiled the DCompute source code and have dcompute.lib. But I am really not good with using libraries and don't know how to use DCompute in my D project(https://github.com/kerdemdemir/DSharpEar/tree/master/DSharpEar). I am not using DUB and compiling with VisualD.

Can you guys please help with importing DCompute into my project?

Regards
Erdem

You should add DCompute as a DUB dependancy.

Hi,

I inited my project with Dub by unsing  "dub init DSharpEar" and I added dependency "dcompute".

Even I give extra parameters for using ldc.

 dub build --compiler=D:\LDCDownload\bin\ldc2.exe --force

I am getting :

Error: static assert  "Need to use a DCompute enabled compiler"

Any suggestions?

Regards
Erdem

do you set "-mdcompute-targets=cuda-xxx" in the dflags for your dub.json for your project?

I have added now after your comment.

But it seems it didn't changed anything.

Here is the dub.json file I have:
{
	"name": "dsharpear",
	"authors": [
		"Erdem"
	],
	"dflags" : ["-mdcompute-targets=cuda-210" ,"-oq", "-betterC"],
	"dependencies": {
		"dcompute": ">=0.0.0-alpha0 <0.1.0"
	},
	"description": "Beamforming with D ",
	"copyright": "Copyright © 2017, Erdem",
	"license": "proprietary"
}

And running "dub build --compiler=D:\LDCDownload\bin\ldc2.exe --force"  fails with:

Are you using latest LDC 1.4? The CUDA backend wasn't enabled for earlier versions.

Yes I am. Actually I can build dcompute's source code so I am sure LDC version is good. Now I am trying to use dcompute within my project.

You are using an old DCompute: that message was changed in https://github.com/libmir/dcompute/commit/cf1420d5377c48f9132f1a9a0f8f06ebb46a6433#diff-b0637c2cde07f2ec8f77f9e3d379fff7

I'm not quite sure how the dub version specs work but I believe "dcompute": "~>0.0.0" should work, or you can force it to use master.
I'm still not sure why it fails with that error though, are you using an old LDC as well? 1.4.0 should work.

I changed my dependency setting in dub file to "dcompute": "~>0.0.0" but still getting the same error message. By the way I am sure my LDC version is good because I can build DCompute source code with same LDC version.

Could this be related to difference in platform like Windows vs. Linux? If so, may be it makes sense to work in a VM that has Nicholas's exact setup.
