c - C 调试功能中的 Visual Studio Code Hello World 不起作用 Programm NullReferenceException :

Question

我尝试在 Ubuntu 18.04.1 上使用 Visual Studio Code 1.30.1 中的调试功能作为调试扩展，我使用 ms-vscode.cpptools 中的 C/C++ 0.20.1。我用 gcc -Wall -g main.c -o main 编译了 main.c

这是main.c的代码

#include <stdio.h> 

int main ()
{
printf("Hello World\n");
}

launch.json 配置

"configurations": [

    {
        // for Linux
        "name": "gdb C",
        "type": "cppdbg",
        "request": "launch",
        "program": "${workspaceRoot}/a.out",
        "args": [],
        "stopAtEntry": false,
        "cwd": "${workspaceRoot}",
        "environment": [],
        "externalConsole": true,
        "MIMode": "gdb",
        //"preLaunchTask": "build cunit",
        "setupCommands": [
          {
            "description": "Enable pretty-printing for gdb",
            "text": "-enable-pretty-printing",
            "ignoreFailures": true
          }
        ]
      }
    ]
  }

当我启动调试器时，我得到

Stopping due to fatal error: NullReferenceException: Object reference not set to an instance of an object

}

我的版本似乎是软件中的一个错误。您可以设置 "externalConsole": false 并且调试功能正常工作(这是一个解决方法)。
