Hallo, ich habe in C++ einen Header erstellt, aber bei der Complierung kommt immer diese Fehlermeldung:
C:\Users\Admin\AppData\Local\Temp\ccdaLGOT.o:lexer.cpp:(.text+0x111): undefined reference to `Token::content[abi:cxx11]() const'
...(Zu lang zum abschicken)
collect2.exe: error: ld returned 1 exit status
Kann mir jemand sagen was der Fehler ist und wie ich ihn behebe?
token.hpp:
#ifndef TOKEN_HPP_
#define TOKEN_HPP_
#include <string>
class Token {
public:
enum class Type {
STRING,

}

}
void Token::clear_content() const noexcept {
m_content.clear(); //Die clear Funktion geht auch nicht
}
void Token::change_type(Type type) const noexcept {

}
Ich hoffe jemand kann mir dabei helfen!
