How can I work with EEPROM

Development Tools IDE 1.x
1

Good evening

I am trying to work with the internal Eeprom of an Arduino Mini Pro

I red taht document and I tried to reproduce it

https://www.arduino.cc/en/Reference/EEPROMPut

I created a library and I have those two files
wi808.h and wi808.cpp.

I did as the following
In the file wi808.ino, I added that line

#include <EEPROM.h>

In the files wi808.h and wi808.cpp, I added that line

#include "EEPROM.h"

In my file WI808.h, I added

struct MyObject {
	float field1;
  	byte field2;
  	char name[10];
};

Just above my class

 class SI808{

Then in my 808.cpp, I added

MyObject customVar = {
            3.14f,
            65,
            "Working!"
          };

        EEPROM.put(0,customVar);

For now, I would ilke to save "Working" but later i would like to save a text of 80 caracters

Then I tried to save "Working at the address 0

When I compile, I have that error message:

In file included from /Users/pierrot/Documents/Arduino/libraries/Wi808/Wi808.h:18:0,
from wi808.ino:2:
/Applications/Arduino.app/Contents/Java/hardware/arduino/avr/libraries/EEPROM/EEPROM.h:145:8: error: declaration does not declare anything [-fpermissive]
static EEPROMClass EEPROM;
^
Erreur lors de la compilation.

At the line 19 of my wi808.h file, I have that code

#define EEPROM

#ifdef EEPROM
  #include "EEPROM.h" // line 19
#endif

Someone can tell me , how I exactely do it?

Excepted of that error, did I start correctely?
How should I do better?

Thank a lot

Ok, forget my problem

I changed

#define EEPROM

with

#define EEPROMM

and correct the

 #ifdef EEPROMM

But I am still doubting about the way I try to do it even if my code compile
