add.h(0): Note: No relevant classes found. No output generated.

这个错误信息通常在使用`doxygen`文档生成工具时出现，`add.h(0): Note: No relevant classes found. No output generated.`表明`doxygen`没有找到`add.h`文件中的任何相关类（classes）以创建文档输出。

`doxygen`是一个用来自动提取、生成API文档的工具，对于C++，它会在注释中寻找特定的标记（如`@class`、`@brief`等）来识别类、函数、枚举等。如果`add.h`中的类定义没有正确地包含这些标记，或者文件中没有任何类定义，`doxygen`就无法识别并生成文档。

确保你在`add.h`中定义了至少一个具有`@class`声明的类，例如：

/**
 * @class Adder
 */
class Adder {
public:
    // 类的其他成员和说明
};

同时检查`add.h`是否被正确的`#include`到了源文件中，并且`doxygen`配置文件（通常是`.doxyfile`）中已经包含了`add.h`所在的目录。

如果你确实有相关的类，但仍然收到这个错误，可能是路径设置不正确或`doxygen`对某些头文件的访问权限不足。
