Defined struct was not declared in this scope error

hi,
I have a problem. My c++ level very very low. I am c# developer. I need to help.
This is my Storage.h

^{#include <EEPROM/EEPROM.h>}
^{#define CONFIG_START 32}
^{#define CONFIG_VERSION "mkb"}
^{class Storage}
^{
^public:
^Storage();
^{static void LoadConfig();}
^{static void SaveConfig();}
^};

and this my Storage.cpp

^{#include "storage.h"}
^{#include <EEPROM.h>}
^{// ESP Eeprom Ayarlar Bilgisi}
^{struct Settings {}
^{char version[4];}
^{// Motor 1 : Sırt Motoru}
^{int MOTOR1_UP_PIN;}
^{int MOTOR1_DOWN_PIN;}
^{int MOTOR1_UP_LIMIT;}
^{int MOTOR1_DOWN_LIMIT;}
^{// Motor 2 : Bel Motoru}
^{int MOTOR2_PIN;}
^{int MOTOR2_DOWN_PIN;}
^{int MOTOR2_UP_LIMIT;}
^{int MOTOR2_DOWN_LIMIT;}
^{// Motor 3 : Ayak Motoru}
^{int MOTOR3_PIN;}
^{int MOTOR3_DOWN_PIN;}
^{int MOTOR3_UP_LIMIT;}
^{int MOTOR3_DOWN_LIMIT;}
^{// Motor 4 : Ayak Motoru}
^{int MOTOR4_PIN;}
^{int MOTOR4_DOWN_PIN;}
^{int MOTOR4_UP_LIMIT;}
^{int MOTOR4_DOWN_LIMIT;}
^{// Okuma Lambası}
^{int LIGHT_PIN;}
^{int LIGHT_SENSIVITY;}
^{bool HAS_CALIBRATED;}
^{bool HAS_CONFIGURED;}
^{} settings;}
^{Storage::Storage() {}
^}
^{void Storage::LoadConfig() {}
^{// To make sure there are settings, and they are YOURS!}
^{// If nothing is found it will use the default settings.}
^{if (EEPROM.read(CONFIG_START + 0) == CONFIG_VERSION[0] &&}
^{EEPROM.read(CONFIG_START + 1) == CONFIG_VERSION[1] &&}
^{EEPROM.read(CONFIG_START + 2) == CONFIG_VERSION[2])}
^{for (unsigned int t = 0; t < sizeof(settings); t++)}
^{((char)&settings + t) = EEPROM.read(CONFIG_START + t);}
^else
^{SaveConfig();}
^}
^{void Storage::SaveConfig() {}
^{for (unsigned int t = 0; t < sizeof(settings); t++)}
^{EEPROM.write(CONFIG_START + t, ((char)&settings + t));}
^{EEPROM.commit();}
^}

and this is "Esp8266App.ino"

^{#pragma region Imports}
^{#include <ESP8266WiFi.h>}
^{#include <WebSocketsServer.h>}
^{#include <Hash.h>}
^{#include <Ticker/Ticker.h>}
^{#include "Storage.h"}
^{#pragma endregion}
^{DeviceState deviceState = NotReady;}
^{void setup() {}
^{USE_SERIAL.begin(9600);}
^{// Hafızadaki ayarları yükle}
^{Storage::LoadConfig();}

^{// Aygıt ayarları yapılmamışsa durumu Ayar Gerekiyor yap}
^{if (!settings.HAS_CONFIGURED)}
^{
^{deviceState = NeedConfig;}
^return;
^}
^{// Motor kalibrasyon ayarları yapılmamışsa durumu Kalibrasyon Gerekiyor yap}
^{if (!settings.HAS_CALIBRATED)}
^{
^{deviceState = NeedCalibrate;}
^return;
^}
^}

this code throwing error.
Error :
Esp8266App.ino: 24:7: error: 'settings' was not declared in this scope
** if (!settings.HAS_CONFIGURED)**

How do you expect 'Esp8266App.ino' to know what the 'settings' structure looks like? Even if it did, 'if (!settings.HAS_CONFIGURED)' makes no sense because it's not referencing a variable (object) of type 'settings'.

I defined "settings" variable after struct defination in Storage.cpp.

struct Settings {
char version[4];

// Motor 1 : Sırt Motoru
int MOTOR1_UP_PIN;
int MOTOR1_DOWN_PIN;
int MOTOR1_UP_LIMIT;
int MOTOR1_DOWN_LIMIT;

// Motor 2 : Bel Motoru
int MOTOR2_PIN;
int MOTOR2_DOWN_PIN;
int MOTOR2_UP_LIMIT;
int MOTOR2_DOWN_LIMIT;

// Motor 3 : Ayak Motoru
int MOTOR3_PIN;
int MOTOR3_DOWN_PIN;
int MOTOR3_UP_LIMIT;
int MOTOR3_DOWN_LIMIT;

// Motor 4 : Ayak Motoru
int MOTOR4_PIN;
int MOTOR4_DOWN_PIN;
int MOTOR4_UP_LIMIT;
int MOTOR4_DOWN_LIMIT;

// Okuma Lambası
int LIGHT_PIN;
int LIGHT_SENSIVITY;

bool HAS_CALIBRATED;
bool HAS_CONFIGURED;

} settings;

How can I refer the "settings" variable in main.ino file ?

The way your code is posted now, it's too difficult to read. Why make it harder for people who are trying to help you FOR FREE?

Start by reading: Read this before posting a programming question ...

Read it all, but pay particular attention to Item #6 - how to properly post your code using "code tags". Before posting again, auto-format your code (ctrl-t in the Arduino IDE) and get rid of superfluous white space and blank lines. Also, post a COMPLETE PROGRAM. All files, not just snippets.

Perhaps with properly posted code, someone will be willing to help you further.
