Start using the Intel® Distribution for GDB* for debugging applications. Follow the instructions below to set up the debugger to debug applications with kernels offloaded to CPU devices.
Intel® Distribution for GDB* is available as part of the Intel® oneAPI Base Toolkit. For more information on oneAPI toolkits, visit the product page.
Visit the Release Notes page for information about key capabilities, new features, and known issues.
You can use a SYCL* sample code, Array Transform, to get started with the Intel® Distribution for GDB*. The sample does not generate errors and simply illustrates debugger features. The code processes elements of the input array depending on whether they are even or odd and produces an output array. You can use the sample to debug on a CPU.
Install the Intel® oneAPI Base Toolkit for Windows* OS.
Install Microsoft Visual Studio* 2019 or 2022.
NOTE:Support for Visual Studio* 2017 is removed starting Intel® oneAPI 2022.2 release.
Build the Application
In Microsoft Visual Studio*, go to File > New > Browse Intel oneAPI Samples and select Debugger: Array Transform.
If you have already fetched the sample or you have your own sample, simply open the solution file with Microsoft Visual Studio*.
In the Solution Explorer, right-click the array-transform project and select Properties. Alternatively, press Alt+Enter.
Under Configuration Properties, select General and set Platform Toolset to Intel® oneAPI DPC++ Compiler.
Under Configuration Properties, select Debugging. Set Command Arguments to cpu.
Select Linker and set the Pass additional options to device compilers field to /Od. This setting disables kernel optimizations to provide a smooth debug experience.
Click Apply to save the changes.
To build the solution, select Build > Build Solution in the main Visual Studio toolbar. In the Output window, verify that the build is successful.
Debug the Application
You are ready to debug your project.
Open Tools > Options > Debugging.
Uncheck the option “Require source files to exactly match the original version”.
Set breakpoint at line 83 in the array-transform.cpp file.
From the Debug menu, select Start Debugging.
Click the Local Windows Debugger menu.
You will see when the thread hits the breakpoint.
