_build directory missing in blinky_example in SDK v5.0.0.34603

[Bluetoothy]

Hi all,

I am currently working on a BLE project based on the PCA10001 evaluation board. I am trying to follow the nRF51 application note. I have done everything that the application note describes, although based on Kepler instead of Juno. At section 2 i get stuck hence gcc/_build does not exist in my blinky_example.

When i attempt to build:

cs-make debug "C:/Program Files/GNU Tools ARM Embedded/4.7 2013q1/bin/arm-none-eabi-gcc" -mcpu=cortex-m0 -mthumb -mabi=aapcs -DNRF51 -DBOARD_PCA10001 -DNRF51822_QFAA_CA --std=gnu99 -Wall -Werror -mfloat-abi=soft -DDEBUG -g3 -O0 -I"../" -I"../../../../Include" -I"../../../../Include/gcc" -I"../../../../Include/ext_sensors" -M ../main.c -MF "_build/main.d" -MT _build/main.o The system cannot find the path specified. cs-make: *** [_build/main.o] Error 1

How do i solve this problem?

Hi, The build folder is modified a little bit from the time the app note is released.

After you compile the code using gcc ARM (run make.exe in gcc folder), you will have _build folder inside gcc folder instead of directly under ble_app_hrs.

Hi Hung,

I updated my post with a stacktrace, furthermore where do i find the GCC ARM make executable, is it included in Sourcery Codebench?

@Bluetoothy: Could you make sure you have GNU tool ARM Embedded installed ? It should be located at : C:\Program Files (x86)\GNU Tools ARM Embedded\4.7 2013q1\lib\gcc\arm-none-eabi. if you have the same version 4.7 2013q1.

You can follow the instruction in chapter 1 nAN29 to know which version you have. Please make sure you have modified the Makefile.windows configuration (GNU _INSTALL_ROOT, GNU_VERSION) correctly, matches with your actual installation of GNU tool ARM embedded.

Make for windows can be downloaded from gnuwin32.sourceforge.net/.../make.htm. But you should be fine using cs-make from code sourcery.

I tried to modify the Makefile.windows to the right directory.

ifeq ($(findstring 86, $(ProgramFiles)), )
	PROGFILES := C:/Users/Administrator/MentorGraphics/Sourcery_CodeBench_Lite_for_ARM_EABI
else
	PROGFILES := C:/Users/Administrator/MentorGraphics/Sourcery_CodeBench_Lite_for_ARM_EABI
endif

GNU_INSTALL_ROOT := $(PROGFILES)
GNU_VERSION := 4.8.1
GNU_PREFIX := arm-none-eabi

Please make sure that you use the supported toolchain from here, and not the CodeSourcery one. The -lnosys library is only part of the CodeSourcery one. See this question for details.
