  - c   索引来自官网离线文档，手动解析生成
  - cpp 索引来自 https://github.com/Guyutongxue/cppreference-index 感谢 @Guyutongxue
- - qt  索引来自 https://github.com/therecipe/qt ，经过二次处理手动解析生成
+ - qt  索引来自 Qt 官网，版本 `Qt 5.13.0`
+ - gcc 命令行选项索引来自[GNU](https://gcc.gnu.org/onlinedocs/gcc-12.2.0/gcc/Option-Index.html)官网，版本 `GCC 12.2.0`
