std::string 显示为<incomplete type>在调试器中</incomplete>

Question

I want to debug my project using vscode, but when i debug all std::string values are shown as incomplete type . in the launch.json i have:

{
    // Use IntelliSense to learn about possible attributes.
    // Hover to view descriptions of existing attributes.
    // For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
    "version": "0.2.0",
    "configurations": [
        {
            "name": "(gdb) Adapter CLI",
            "type": "cppdbg",
            "request": "launch",
            "program": "${workspaceFolder}/build-debug/cli/src/adapterCli",
            "args": ["${workspaceFolder}/cli/src/config.ini"],
            "stopAtEntry": true,
            "cwd": "${workspaceFolder}",
            "environment": [],
            "externalConsole": false,
            "MIMode": "gdb",
            "setupCommands": [
                {
                    "description": "Enable automatic structuring and indentation for gdb.",
                    "text": "-enable-pretty-printing",
                    "ignoreFailures": true
                }
            ],
            "miDebuggerPath": "/usr/bin/gdb"
        }   
    ]
    
}

Answer 1

what should i do to solve the problem?

Since you are using clang you have 2 options to solve "incomplete type" problem:

1. This is clang specific problem, so if you can use another compiler you can just use gcc instead of clang .
2. You can continue using clang but you will have to install debug info for libstdc++ library. The exact way how to install it depends on the OS you are using. For Fedora/RedHat/CentOS use sudo dnf debuginfo-install libstdc++-<some_version_here>.x86_64 , see https://stackoverflow.com/a/42031150/72178 . For Ubuntu/Debian use sudo apt-get install libstdc++6-dbgsym , see https://stackoverflow.com/a/65565897/72178 .
3. You can also use clang with -fno-limit-debug-info option, see https://stackoverflow.com/a/58527425/72178 .
