使用调试器时出现Vscode错误

在尝试使用VSCODE调试c++时，我遇到了以下错误：

> Executing task: /usr/bin/g++ -g /home/sa/Genesis/Dev/TcpSocketClassTester/.vscode/launch.json -o /home/sa/Genesis/Dev/TcpSocketClassTester/.vscode/launch <

/usr/bin/ld:/home/sa/Genesis/Dev/TcpSocketClassTester/.vscode/launch.json: file format not recognized; treating as linker script
/usr/bin/ld:/home/sa/Genesis/Dev/TcpSocketClassTester/.vscode/launch.json:1: syntax error
collect2: error: ld returned 1 exit status
The terminal process terminated with exit code: 1

Terminal will be reused by tasks, press any key to close it.

看起来你犯了一个错误。实际上你试图编译的是与你正在工作的cpp文件不同的JSON文件。你应该先切换到cpp代码的选项卡，然后再运行run task或者run build task。

找到了我的问题：

  • 这些文件(launch.json和tasks.json)是由VSCode为我生成的。
  • 但是，请删除此行："preLaunchTask": "g++ build active file",
  • 同时修改此行："program":"${workspaceRoot}/TcpSocketClassTester/TcpSocketClassTester",
  • 最后删除文件：tasks.json（不需要）

根据Darcy的回答，它试图编译错误的文件。
在您的tasks.json中，您可以在args数组中看到这一行："${file}"，它会填充您想要编译的文件的完整路径。
此行的值因当前焦点文档而异。因此，可以安全地假设您正在尝试运行任务时，在vscode上有task.json文件处于焦点状态。只需将其更改为您想要编译的.cpp文件，按F5或单击调试选项卡中的播放按钮即可正常工作。
