我正在尝试使用Ubuntu Linux在Visual Studio Code中配置C / C ++工作区,但我不知道如何使调试器正常工作。我从互联网上复制了一个'tasks.json'文件,以便可以通过按F5来编译我的代码,但我认为它会导致调试器出现某种问题,因为每次我尝试进入调试模式时,都会出现错误“找不到任务“ gcc建立活动文件”弹出。 这是2个json: task.json

预先感谢您的帮助,我真的很笨。

在您的task.json
文件中,没有任务被标记为“ gcc构建活动文件”,而preLaunchTask
文件中的launch.json
则不需要该任务。
因此,您可以更改任务的label
或更改preLaunchTask
的内容以使其匹配。
只需将preLaunchTask
的内容更改为“ g ++构建活动文件”。它将起作用。

您需要指定文件的路径和名称。当然,只有在二进制文件使用g标志编译(输出变得更重且压缩更少)的情况下,调试才可能进行。
launch.json将映射到二进制文件
“程序”:“ $ {workspaceFolder} /a.out”,
task.json与如何编译
有关“参数”:[ “-G”, “ $ {workspaceFolder} / *。cpp”, “ -o”, “ $ {workspaceFolder} /a.out”

如果无法通过vscode使其工作,则可能要使用其他工具,例如GDB。 GDB在Linux / VM和WSL中的Terminal中也可以很好地工作。
