const std::string& 0.1

0.1 is actually a constant. A valid variable name is expected. If you don't need that argument for anything else, just remove it (leave brackets empty). If the function must take a parameter of type string by reference, just remove the constant. An argument with no name is not used by the function; however, it allows for dealing with compatibility issues. To keep the parameter usable, try the following:

void setVersion(const std::string& version) {m_appVersion = version;}

where version can be any valid variable name.

I hope this helps! :D
