    "No Source Available" when trying to debug OpenCL kernel with CodeXL

    zoomzoom

      I am trying to debug an OpenCL kernel using CodeXL from within Visual Studio 2012. I set a breakpoint at clEnqueueNDRangeKernel and hit F11. The result is a new tab being opened which is labeled "No Source Available". It also says: The current thread is not currently running code or the call stack could not be obtained".

       

      However in CodeXL Properties window I can see information about the kernel I'm trying to debug: Kernel Function Name, # of Arguments, Arguments Information.

       

      Debugging the application from CodeXL, (no Visual Studio), shows a similar problem. In the CodeXL Explorer window, I can see all the kernels listed under OpenCL Programs, OpenCL Program 1, but trying to get into the kernel does not work. If I double click on the kernel name, a new window gets opened labeled "CL Context 1 Kernel 4 -....", but it is empty, no code.

       

      How can I make it work?

       

      Is there an CodeXL log file that I could check to see why it can't open and display the kernel code?

       

      Where does CodeXL look for the OpenCL code?

       

      I have also tried CodeXL from within Visual Studio with the Matrix Multiplication sample from AMD APP SDK and I could step in inside the kernel.

       

      Here are a few details about the project:

      - Visual Studio solution with several projects

      - The main project statically links with a lib file generated by another project inside the solution. This second project is the one containing the OpenCL code

      - There is one single OpenCL source file

      - The OpenCL source file is not included in the project; I have tried adding it, but nothing changed

      - The OpenCL program is created with clCreateProgramWithSource

      - clBuildProgram is called with the options string being empty, ""

       

      Version information:

      - CodeXL version 1.5.6571.0

      - AMD APP SDK 2.9-1

      - AMD FirePro W5100

      - Driver Date 5/20/2014

      - Driver Version 13.352.1009.0

       

      Thanks.
