Compile the firmware

[ChubbyBunny1]

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.
make (e=2): ─ίΊ ί▀Ίάώ ϊΫΊάΪ▐ ύ ί²±ί≤ύ ΪΎΫ ΆάϋΎ±ώ≤Ή▌ΊΎΫ ά±≈ί▀ΎΫ άΏⁿ ΪΎ ≤²≤ΪύΉά.
make: *** [Makefile:49: usbdrv/usbdrv.o] Error 2

Can anyone help with this?
