我将其添加到 .vscode/c_cpp_properties.json 内的包含路径中:

I added this to the include path inside .vscode/c_cpp_properties.json:

        "includePath": [
            "${workspaceFolder}/**",
            "/usr/include/gtk-3.0",
            "/usr/include/glib-2.0",
            "/usr/lib/x86_64-linux-gnu/glib-2.0/include",
            "/usr/include/pango-1.0",
            "/usr/include/harfbuzz",
            "/usr/include/cairo",
            "/usr/include/gdk-pixbuf-2.0",
            "/usr/include/atk-1.0"
        ],
