Makefile to build several files in different folders

Hi

I have been trying to use MSP GCC compiler. I have written a makefile for single file and able to compile and flash in the MSP430 device.

I don't know how to write makefile for many source files in different folder inter dependent with each other.

I am developing a serial deriver folder and file structure is as follows
serial_driver/App
serial_driver/App/inc/app.h
serial_driver/App/inc/app.c
serial_driver/controller
serial_driver/controller/inc/hardware.h
serial_driver/controller/inc/globaldef.h
serial_driver/controller/src/ctrl.c
serial_driver/UART
serial_driver/UART/inc/uart.h
serial_driver/UART/src/uart.c

Can any give some ideas to write make files for this project and how to expand in future bigger projects.

Thanks and Regards,
Ashok Kumar P

CC=gcc-msp430

DIR1=serial_driver/App
DIR2=serial_driver/controller
DIR2=serial_driver/UART

INCLUDES=$(DIR1)/inc \
$(DIR2)/inc \
$(DIR3)/inc

SRCS=$(DIR1)/src/app.c \
$(DIR2)/src/controller.c \
$(DIR3)/src/UART.c

#fillup your library directory and libs
LIBDIR=
LIBS=


xxx.exe:
$(CC) $(INCLUDES) \
$(SRCS) -o xxx.exe $(LIBDIR) $(LIBS)

use 'tabs' apropriately.

is your OS windows or linux?

Makefile snipets

INCLUDES = ${MCUDIR}/inc/hardware.h\
${MCUDIR}/inc/led.h\
${MCUDIR}/inc/serial.h\
${MCUDIR}/inc/mcu.h\
${APPDIR}/inc/app.h

SRCS = ${APPDIR}/src/app.c\

${MCUDIR}/src/mcu.c\
${MCUDIR}/src/serial.c

${NAME}.elf: ${OBJECTS}
${CC} -mmcu=${CPU} -o ${INCLUDES} ${SRCS}

Any help please.

Attached the full makefile.

Attached ythe makefile txt format

one possibility is , the directory 'mcu' is not completely specified.

say , "./mcu" , or "/home/mcu".

another one is error in final line.

insted of:
${NAME}.elf: ${OBJECTS}
${CC} -mmcu=${CPU} -o ${INCLUDES} ${SRCS}

it should be:
${NAME}.elf: ${OBJECTS}
-->note this line: ${CC} -mmcu " ??what is this--->${CPU}" -o $(NAME.elf ${INCLUDES} ${SRCS}
