Debugging an OpenCL™ Application
Tutorial: Debugging with Intel® Distribution for GDB*
To debug OpenCL™ applications with Intel® Distribution for GDB*, make
sure you use the following flags when calling the
clBuildProgram
function:- -g -cl-opt-disableto enable the debug information and disable optimizations inside the kernel
- -s <full_path_to_kernel.cl>to point to the kernel source file.This allows you to set a breakpoint in the following format:breakpoint kernel.cl:<line number>.
Launch the debugger as follows:
gdb-oneapi <application>
To start debugging, you must set a pending breakpoint because the kernel
source file is not known to the debugger yet:
set breakpoint pending on
break kernel.cl:<line number>
run
At runtime, the kernel sources are loaded to the debugger and the
breakpoint is hit, both for CPU and GPU offloads.
