ubuntu中使用vscode进行cuda c代码debug出现 no such file or directory 的问题

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "CUDA C++: Launch",
      "type": "cuda-gdb",
      "request": "launch",
      "program": "${fileDirname}/test.err",
      "debuggerPath": "/usr/local/cuda-12.0/bin/cuda-gdb",
      "preLaunchTask": "mynvcc",
    },
    {
      "name": "CUDA C++: Attach",
      "type": "cuda-gdb",
      "request": "attach"
    },
   
  ]
}

问题提要：配置launch.json文件的时候，需要生成的program（如上例为test.err）成功生成，但vscode提示test.err no such file or directory的问题

原因：vscode debug时会进入debug下的文件路径，和我们想要的文件路径并不一致。

解决方法：将launch.json文件进行修改即可。

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "CUDA C++: Launch",
      "type": "cuda-gdb",
      "request": "launch",
      "program": "${fileDirname}/test.err",
      "debuggerPath": "/usr/local/cuda-12.0/bin/cuda-gdb",
      "preLaunchTask": "mynvcc",
      "cwd":""
    },
    {
      "name": "CUDA C++: Attach",
      "type": "cuda-gdb",
      "request": "attach"
    },
   
  ]
}

附成功debug的几个其他json文件：

tasks.json

{
    "version": "2.0.0",
    "tasks": [
        {
            "label": "mynvcc",
            "type": "shell",
            "command": "nvcc",
            "args": [
                    "-std=c++17",
                    "-g",
                    "-G",
                    "-lz",
                    "-o",
                    "${fileDirname}/test.err",
                    "main.cu"],
        }
    ]
}

c_cpp_properties.json

{
  "configurations": [
    {
      "name": "Linux",
      "includePath": [
        "${workspaceFolder}/**"
      ],
      "compilerPath": "/usr/local/cuda-12.0/bin/nvcc",
      "cStandard": "c17",
      "cppStandard": "gnu++17",
      "intelliSenseMode": "linux-gcc-x64",
      "compilerArgs": [
        ""
      ]
    }
  ],
  "version": 4
