go-opencl's Issues

no proper C includes

On a linux machine i see this:

jpad@guru:~$ go get github.com/samuel/go-opencl/cl

github.com/samuel/go-opencl/cl

prog/go/extern/src/github.com/samuel/go-opencl/cl/cl.go:19:17: fatal error: cl.h: No such file or directory
// #include "cl.h"
^
compilation terminated.

I guess that on an OS X machine there will also be similar troubles. I think something like this would be a solution:

/*
#cgo CFLAGS: -I CL
#cgo !darwin LDFLAGS: -lOpenCL
#cgo darwin LDFLAGS: -framework OpenCL
#ifdef APPLE
#include "OpenCL/opencl.h"
#else
#include "CL/opencl.h"
#endif
*/
import "C"

...

Suggestions

Hi,

This appears to be abandoned and is incomplete - but its the first hit return by google when looking for golang and opencl. Is there a better version to be using?

Thanks,
Matt

Null platformIds; Not getting any opencl platforms on Ubuntu

System

OS: Windows 10 w/ WSL2; Ubuntu 18.04.5 LTS
GPU: Intel UHD 620 (iGPU)
OpenCL Installable Client Driver used: https://github.com/OCL-dev/ocl-icd

Reproduced error

Tried running cl.GetPlatforms(), with no prior preparation/setup. I keep getting:

panic: runtime error: invalid memory address or nil pointer dereference [recovered]
	panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x602ac6]

Not sure what I'm doing wrong here...

cl_test.go

Where file cl_test.go

no license present

Hi -- Can you please add some sort of permissive license file/indicator?

should add `#define CL_TARGET_OPENCL_VERSION 120` before include?

should add

#define CL_TARGET_OPENCL_VERSION 120

before including any cl.h
