Can not compile for ESP8266 wifi module

Hello, I have followed many tutorials on the net for learning to use the ESP8266 wifi module.
But I would now upload the webserver sketch into by using Arduino 1.6.5 with the "GeneriESP8266 board" and teh esptool too.
I have installed the ESP8266 library but I can compil the example webserver sketch and I don't know why.
If somebody could help me, it would very nice.

I can compil the example webserver sketch and I don't know why.

Most people would be OK with that.

Some more details would be useful.

No, it was a mistake; I can NOT compile !

Sorry, I have to go to the beach, I will give more details later but the two jointed pieces are details.

While you are at the beach, I'll look for a picture of an answer. Or not.

A link to the library and ALL of your code AS TEXT is the next order of business.

There is the link of the library installed by the arduino IDE:

http://arduino.esp8266.com/stable/package_esp8266com_index.json

and the same error reported:

Arduino : 1.6.5 (Windows XP), Carte : "Generic ESP8266 board"

Les options de compilation ont été modifiées, tout sera recompilé

The errors are because the *** functiuns are not declared.

Isn't because there is no parse.h in the parse.cpp folder ?

Looks like you have an ESP8266 core installed in the Program Files\Arduino\hardware folder when it should be in the C:\Users\username\AppData\Roaming\Arduino15\packages folder. Try removing the old core.

I have the same files at Programfiles\xxx than c:\documents and setting\administrateur\ as you can on the picture:

and I still have the same problem...

Did you follow the installation instructions here:
