arduino bbq smoker temp controller

Hi,
im trying to reproduce an arduino bbq smoker temp controller seen here; Homebrew BBQ Temperature Monitor/Controller VERSION 2

Since I only want it basic I have try to disable all the parts of code that rely on wishield and keepalive fonction to keep only the lcd part. So far i am getting those errors:

C:\Users\pop\AppData\Local\Temp\build8992420869385269522.tmp/core.a(main.cpp.o): In function main': C:\Arduino\hardware\arduino\avr\cores\arduino/main.cpp:40: undefined reference to setup’
C:\Arduino\hardware\arduino\avr\cores\arduino/main.cpp:43: undefined reference to `loop’
collect2.exe: error: ld returned 1 exit status
Erreur de compilation.

Thx in advence for the help i’ll find here.

You commented out setup() and loop(), so it is though they don't exist. The compiler is telling you that.
