In file included from led.c:2:
warning: #warning "device type not defined"

The warning says it all: you must tell avr-gcc what device you use (-mmc=....) since ports,etc differ from one chip to the other. Have a look a the nice Makefile provided with Winavr (it works also on unix/linux),
you'll spare some time figuring how to compile correctly.


i was more concerned with this line led.c:6: error: `DDRD' undeclared (first use in this function). or will that be cleaned up by fixing the first warning?
