使用const unsigned long的代码块时出现GCC错误(GCC error while using code blocks for const unsigned long)

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。

当我删除无符号修饰符时，一切正常。可能我过去24小时都在编码，所以我看不出什么是错的，我很惊讶。我不想睡觉，直到该代码编译它的方式。

我正在使用ubuntu和gcc 4.4.3上的代码块

谢谢你们

Consider this code

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

it does not compile and the compiler gives me this weird error.

when i remove the unsigned modifier, everything works fine. Probably i have been coding for the last 24 hours so i dont see whats wrong, and am struck. I dont want to sleep until that code compiles the way it is.

am using codeblocks on ubuntu and gcc 4.4.3

Thanks men
