Can't convert pointers to StringRef

[arguiot]

I keep getting theses errors:

error: no matching function for call to 'Input'
                                Component input_first_name = Input(&first_name, "first name");
                                                                   ^~~~~
/build/_deps/ftxui-src/include/ftxui/component/component.hpp:34:11: note: candidate function not viable: no known conversion from 'std::string *' (aka 'basic_string<char> *') to 'ftxui::StringRef' for 1st argument

Hellow,

The StringRef adapter is declared as:

/// @brief An adapter. Own or reference a constant string. For convenience, this
/// class convert multiple mutable string toward a shared representation.
class StringRef {
 public:
  StringRef(std::string* ref) : address_(ref) {}
  StringRef(std::string ref) : owned_(std::move(ref)) {}
  StringRef(const wchar_t* ref) : StringRef(to_string(std::wstring(ref))) {}
  StringRef(const char* ref) : StringRef(std::string(ref)) {}
  std::string& operator*() { return address_ ? *address_ : owned_; }
  std::string* operator->() { return address_ ? address_ : &owned_; }

 private:
  std::string owned_;
  std::string* address_ = nullptr;
};

Since there is:

StringRef(std::string* ref)

I expect conversion from string* to work. I don't expect this error message. Could you provide instructions about how to reproduce this?

Hmmm, not sure it's working... I just used the starter project, and replaced the content of main.cpp with your example, input.cpp. And I get this error. Very strange...

Can you copy the file you want to compile?
