Enable CUDA C/C++ support in vs-code in Windows 10

In this blog, I want to show users how to set up vs-code for CUDA C/C++ code in Windows 10.

Introduction

I’ve been working on cuda programming in Visual Studio, which can be set up easily. However, since I play with vs-code, I would like to use vs-code for cuda as well. So In this blog, I want to show users how to set up vs-code for cuda in Windows.

There are some major steps you need to take, in order to run/debug cuda code using vs-code.

(Optional, if done already) Enable Linux Bash shell in Windows 10 and install vs-code in Windows 10.
Download the extension in vs-code: vscode-cudacpp. It is mainly for syntax and snippets.
Download the sample code from my GitHub repository.
Press Ctrl+Shift+B in vs-code, choose build to compile the code. Choose run to run the executable.
Currently it is not able to enable cuda-debugger for cuda in vs-code in Windows. If you were to do everything in bash, then there might be a possibility to configure cuda-debugger.
But it is OK to use Windows C/C++ debugger, to only debug CPU code.
