topic Hi Zvi, in OpenCL* for CPU

kernel with pipe parameter: compilation error

ZVere — Wed, 20 Jan 2016 21:10:51 GMT

Hello,

I tried compiling the following kernel with the last version of OpenCL SDK:

__kernel void pipe_producer (__write_only pipe float rng_pipe)

{

}

And got the following errors:

1:3:30: error: expected parameter declarator
1:3:43: error: expected ')'
1:3:29: note: to match this '('
Compilation failed

Can you tell why ?

Regards,

Z.V
