I am using windows trying to compile it with make main.hex, i am getting this error:
avr-gcc -Wall -O2 -std=c99 -Iusbdrv -I. -mmcu=atmega8 -c usbdrv/usbdrv.c -o usbdrv/usbdrv.o
process_begin: CreateProcess(NULL, avr-gcc -Wall -O2 -std=c99 -Iusbdrv -I. -mmcu=atmega8 -c usbdrv/usbdrv.c -o usbdrv/usbdrv.o, ...) failed.
