Im trying to use XCode to compile avr program with arduino libs but seems like something wrong with my Makefile because it throws me warnings like 

# warning "F_CPU not defined for <util/delay.h>"

but I use -D on CC and CXX which should define stuff I thought, here is my Makefile:

TARGET              = firmware
MCU                 = atmega32u4
F_CPU               = 16000000L
USB_VID             = 0x2a03
USB_PID             = 0x8036
USB_PRODUCT         = "USB Device"
USB_MANUFACTURER    = "Unknown"
ARDUINO_VERSION     = 107010

CC   =
CXX  = avr-g++
AR   = avr-ar
COPY = avr-objcopy
SIZE = avr-size
DUDE = avrdude


CFLAGS = -c -g -Os -w -ffunction-sections -fdata-sections -MMD -mmcu=$(MCU) -DF_CPU=$(F_CPU) -DARDUINO=$(ARDUINO_VERSION) -DARDUINO_AVR_LEONARDO -DARDUINO_ARCH_AVR -DUSB_VID=$(USB_VID) -DUSB_PID=$(USB_PID) -DUSB_MANUFACTURER=$(USB_MANUFACTURER) -DUSB_PRODUCT=$(USB_PRODUCT)

CXXFLAGS = -c -g -Os -w -fno-exceptions -fno-threadsafe-statics -MMD -mmcu=$(MCU) -DF_CPU=$(F_CPU) -DARDUINO=$(ARDUINO_VERSION) -DARDUINO_AVR_LEONARDO -DARDUINO_ARCH_AVR -DUSB_VID=$(USB_VID) -DUSB_PID=$(USB_PID) -DUSB_MANUFACTURER=$(USB_MANUFACTURER) -DUSB_PRODUCT=$(USB_PRODUCT)

  • Where did you read that you want to use $(shell ...) for all commands?

  • found in web, XCode show error " *** missing separator . Stop" if I not using shell

  • @user840250 Do you have a tabs as indents? Four spaces won't work in Makefile.

  • You're confusing CPP (the C PreProcessor, avr-cpp when called from avr-gcc or avr-g++) with CXX (avr-g++) with disastrous results.

You are using $(CPPFLAGS) for *.cpp files but only $(CXXFLAGS) are defined.

This should be obvious from command line (if you enable showing executed commands for make)

And also:

  • CC =
  • using $(CPP) again only $(CXX) is defined

And don't forget Makefile needs tabs for indenting target commands (here you have four spaces, but it might be just replaced by SE)
