How to debug C++AMP code locally in Visual Studio 2019/2022

Carl 20

Graphics card: Nvidia GF 3060;

System：Windows 10 Professional;

Environment: Visual Studio 2022

Debug mode: Local Windows debugger (not remote debugging);

Debug type: Just GPU ( C++ AMP );

Every time debugging is started, an error pop-up appears: 'The target computer does not have the debugging driver for the selected debugging accelerator installed';

So, what should I do to debug the code in the kernel function section of 'parallel_for_each'???

Hello @Carl,

Welcome to Microsoft Q&A forum.

This document: To debug the GPU code says

In the Debugger Type list, verify that Auto is selected. Auto is the default value. In versions before Windows 10, GPU Only is the required value instead of Auto.

So, if you try to change to select and set the Debugger Type to Auto, will it work?

Feel free to let us know the result.

Sincerely,

Tianyu

According to the answer, there are two situations:

Debugging a single step into a kernel function, but unable to capture the values of variables in the "Local Variables" window or "Automatic Window"; Display as' An unspecified error occurred 'in the variable value field;

No matter how the project is cleaned and recompiled, the breakpoint in the kernel function cannot be hit. The prompt is: "Currently, the breakpoint cannot be hit；

Excuse me, how did the above problems arise and how should they be resolved?

Firstly, thank you for the expert's response. Based on the occurrence of the above two situations, I have questioned the mistake of using the "auto" debugging method before, so I have switched to the "GPU only" option; If using the "Auto" option is the correct way, but the above two situations occur in debugging multiple projects, how can I solve them?
