Does the cpu OpenCL runtime not support printf ? It seem to not work in my kernel.

Dear eveyone

     My kernel which use the 'printf' function seem to not work. I got nothing when I try to develop a program. But it work well when I use Nuclear display OpenCL runtime.

     I try to use a simple kernel to print, but nothing expected happens.

Example like that does not work.

kernel void maintest(){

    printf("%s\n", "this is a test string\n");

}

My cpu is i5-6300hq which working in windows10 pro.  The runtime comes from Intel® Process Runtime for OpenCL™  and shuld be the latest version.  I will appreciate that some infomation help me to solve it.

Hi,

Can you provide a reproducer? I tested an example, printf can work on my side. 

Thanks.
