Hi!
I'm trying to compile my first project "nutos.c" and my compiler (avr-gcc 3.3.1) gives me this error:

avr-gcc -g -Wall -O5 -mmcu=atmega128    -c -o nutos.o nutos.c
nutos.c: In function `NutAppMain':
nutos.c:40: warning: unused variable `i'
avr-gcc -g -Wall -O5 -mmcu=atmega128  -Wl,-Map,nutos.map -o nutos.elf nutos.o 
c:\WinAVR\bin\..\lib\gcc-lib\avr\3.3.1\..\..\..\..\avr\lib\avr5\crtm128.o(.init9+0x0): undefined reference to `main'
make: *** [nutos.elf] Error 1

Can you help me?
I'm using WinAVR 20030913 tool set and Ethernut 3.3.0 under W2k.
Thank you for any answer.
Michal
