Unable to Compile nrf51 SDK example from directory other than SDK

问题

I'm devloping application on nRf51 for that i'm using... SDK : nRF51_SDK_7.2.0_cf547b5 Tool chain : GNU tools arm Embedded [arm-none-eabi version 4.9.3] Dev Board : PCA10028(nRF51 DK)

I'm using following example. C:\nRF51_SDK_7.2.0_cf547b5\examples\peripheral\blinky When i compile this example using makefile at location C:\nRF51_SDK_7.2.0_cf547b5\examples\peripheral\blinky\pca10028\blank\armgcc it compiles well and also generate binary/hex.

I want to move this blinky example to D Drive. So now my example is at location D:\blinky. I'm compiling this example using makefile at location D:\blinky\pca10028\blank\armgcc I have Modified SDK PATH in makefile as per this

PROJECT_NAME := blinky_blank_pca10028

export OUTPUT_FILENAME
#MAKEFILE_NAME := $(CURDIR)/$(word $(words $(MAKEFILE_LIST)),$(MAKEFILE_LIST))
MAKEFILE_NAME := $(MAKEFILE_LIST)

When i'm compiling this using "make" in cmd.exe then i get

D:\blinky\pca10028\blank\armgcc>make
rm -rf _build
makefile
mkdir _build
Compiling file: Main.c
Linking target: nrf51422_xxac.out

arm-none-eabi-gcc.exe: error: _build/gcc_startup_nrf51.o: No such file or directory
make: *** [nrf51422_xxac] Error 1

Any solution on this? Thank you.

回答1:

It seems that your absolute source file paths are incorrect :

$(TOOLCHAIN_PATH)/components/toolchain/system_nrf51.c
$(TOOLCHAIN_PATH)/components/drivers_nrf/hal/nrf_delay.c 
$(TOOLCHAIN_PATH)/components/toolchain/gcc/gcc_startup_nrf51.s

preventing the corresponding objects from being built.

Please update TOOLCHAIN_PATH - or use another variable - to reflect your new D: location.
