考虑这段代码
class Reflect : public flemax::annotation::XAnnotation {
public:
Reflect(const unsigned long id, const std::string& home, const char type, const std::string& name = "me", const int value = 4, const bool valid = false, const signed char gender = 'M') : id_(id), home_(home), type_(type), name_(name), value_(value), valid_(valid), gender_(gender){}
~Reflect() {}
const unsigned long id() { return id_; }
const std::string& home() { return home_; }
const char type() { return type_; }
const std::string& name() { return name_; }
const int value() { return value_; }
const bool valid() { return valid_; }
const signed char gender() { return gender_; }
private:
const unsigned long id_;
const std::string home_;
const char type_;
const std::string name_;
const int value_;
const bool valid_;
const signed char gender_;
}; // class Reflect
它没有编译,编译器给了我这个奇怪的错误。

当我删除 unsigned 修饰符时,一切正常。可能我在过去的 24 小时里一直在编码,所以我看不出有什么问题,我很震惊。在该代码按原样编译之前,我不想睡觉。
我在 ubuntu 和 gcc 4.4.3 上使用代码块
谢谢男人
