Hi,

I have attached my codes(my_trial_dpcpp.cpp)
When I run this program, it shows an error: implicit capture of this is not allowed in kernel functions.
Is there a way I can access member function in kernel code.
I appreciate your help.
Thank you.

Hi,

 

Thanks a lot for the response.

I have the following issues:

  1. When I uncomment findNext function, I see an error in at 'extern': invalid storage class for a class member
  2. I am trying to use findNext function inside findBest. Is there a way to do so? 

I appreciate your help.

 

Thank you.

Hi  @student4,

If you would like to call findNext() function from kernel and findNext() does not use non-static members of class Sample (vectors B and shat), then just add static keyword to fix the compilation:

static complex<float> findNext(sycl::accessor <complex<float>>BAccess)
{
	complex<float> c = BAccess[0];
	return c;
}

Thanks,

Mariya

Hi @student4,

There was no feedback from you on this thread for a week.

I assume that the above recommendation helped and stop monitoring this thread.


Thanks,

Mariya
