embedded - Makefile for nrf51sdk -

i working on programming nrf51822 evaluation board(this one). have been looking @ this site program , have gotten blinking program work.

i want modify makefile provided on site mentioned, such when go along pretty have add list of files compile. below have been trying work, not makefiles.

cc            := /opt/arm-2012.09/bin/arm-none-eabi-gcc objcopy       := /opt/arm-2012.09/bin/arm-none-eabi-objcopy  nrf51_sdk     := /opt/nrf51sdk nrf51_include := $(nrf51_sdk)/nordic/nrf51822/include nrf51_src     := $(nrf51_sdk)/nordic/nrf51822/source  cpu           := cortex-m0 board         := board_pca10001  objdir  = . objdir += $(src)/templates/  includedirs = $(nrf51_include) includedirs += $(nrf51_include)/gcc  define  = board_pca10001 define += nrf51  cflags  = -mcpu=$(cpu)  cflags +=-mthumb cflags += $(patsubst %,-d%, $(define)) cflags += $(patsubst %,-i%, $(includedirs)) cflags += -c  src  = main.c src += $(nrf51_src)/templates/system_nrf51.c src += $(nrf51_src)/nrf_delay/nrf_delay.c  assembly_src += $(nrf51_src)/templates/gcc/gcc_startup_nrf51.s   all: main.bin main.hex  %.o : %.c  @echo "compiling: " $<   $(cc) $(cflags) $<  %.o : %.s    @echo "compiling: " $<   $(cc) $(cflags) $<  main.out: $(src) $(assembly_src)   $(cc) -l"/opt/arm-2012.09/arm-none-eabi/lib/armv6-m" -l"/opt/arm-2012.09/lib/gcc/arm-none-eabi/4.7.2/armv6-m" -xlinker -map=main.map -mcpu=$(cpu) -mthumb -mabi=aapcs -t$(nrf51_sdk)/nordic/nrf51822/source/templates/gcc/gcc_linker_script_nrf51.ld main.o system_nrf51.o nrf_delay.o gcc_startup_nrf51.o -o main.out  main.bin: main.out   $(objcopy) -o binary main.out main.bin  main.hex: main.out   $(objcopy) -o ihex main.out main.hex  install: main.bin   sed  's#\[\[--filename--\]\]#$(pwd)/main.bin#' segger/burn-template.seg > burn.seg   ./segger/segger.sh $(pwd)/burn.seg  clean:   rm *.o *.out *.hex *.seg *.map *.bin *.hex 

when runs make outputs following:

/opt/arm-2012.09/bin/arm-none-eabi-gcc -l"/opt/arm-2012.09/arm-none-eabi/lib/armv6-m" -l"/opt/arm-2012.09/lib/gcc/arm-none-eabi/4.7.2/armv6-m" -xlinker -map=main.map -mcpu=cortex-m0 -mthumb -mabi=aapcs -t/opt/nrf51sdk/nordic/nrf51822/source/templates/gcc/gcc_linker_script_nrf51.ld main.o system_nrf51.o nrf_delay.o gcc_startup_nrf51.o -o main.out arm-none-eabi-gcc: error: main.o: no such file or directory arm-none-eabi-gcc: error: system_nrf51.o: no such file or directory  arm-none-eabi-gcc: error: nrf_delay.o: no such file or directory arm-none-eabi-gcc: error: gcc_startup_nrf51.o: no such file or directory make: *** [main.out] error 1 

is there around here can me this?

i figured out, , sharing if wants know how did it. if comment on how make 'better'

this @ least works :)
