Debugging OpenCL on CPU

Question

I'm trying to debug OpenCL kernels on CPU target, following this guide without success. The kernel builds, app runs, but the breakpoints are not hit. There is a statement "The Debugger requires setting the global ID of the work-item to debug before the debugging session starts.", but no information on where to set or how the global ID. Anybody has a working boilerplate project for this or suggestions? thanks!

Update, after desparation, I tried VS 2015 + older Opencl SDK from intel and that actually adds a "Code builder" menu to the Visual Studio. So I was missing that part in the VS2017 install. However, problem persists, I set the global ID of interest, breakpoint gets not hit. — Miro Krsjak

Try to debug with Oclgrind https://github.com/jrprice/Oclgrind https://github.com/jrprice/Oclgrind/wiki example: Oclgrind -i ./appl
