Make file failing

[Eric Busch]

Hi, I am trying to build the ble_blinky_client example in the nRF5 SKD v17.0.2

The make file given in the armgcc folder is failing to build the target.

I am getting the following output

C:\Nordic_SDKS\nrf5_SDK_for_Mesh_v5.0.0_src\examples\mesh_hub\ble_app_blinky_c\pca10040\s132\armgcc>make make: *** No rule to make target `C\:/Nordic_SDKS/nRF5SDK1702d674dde/modules/nrfx/mdk/gcc_startup_nrf52.S', needed by `_build/nrf52832_xxaa/gcc_startup_nrf52.S.o'. Stop.

How do I fix this?

Hello, 

I'm confused. What example are you trying to build? You write ble_blinky_client example in nRF5 SDK v17.0.2, however point to the nRF5 SDK for Mesh. 

Please change to nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_blinky

Kind regards,
Øyvind

I copied the example into a custom example folder. 

I updated SK_ROOT inside the makefile to be

SDK_ROOT := C:/Nordic_SDKS/nRF5SDK1702d674dde

Is there something else I need to change to make this work?

Thank you,

Eric

If you are trying to integrate a nRF5 SDK v17.0.2 example into the nRF5 SDK for Mesh, please have a look at this guide on Integrating Bluetooth mesh into nRF5 SDK examples.

That said, the path you are defining seems to cause an issue: C\:/ 

There is a slash too much there. Did you try with slashes the other way? I.e. C:\Nordic_SDKS\nRF5SDK1702d674dde\ ? What are you building the project with?

[Eric Busch]

I am just using make to build the project. This issue seems to occur no matter where the path is. I have opened up a fresh untouched sdk, cd into the armgcc folder of the ble_app_blink_c example and typed make. It will typically get through compilation the first time, but as soon as I type make again it can't finds some folder/file and has the inserted backslash.

What is the full output of "make VERBOSE=1"? What is the output of make --version ?

[Eric Busch]

make VERBOSE=1

make_verbose.txt

If I rerun make once the _build folder is created I get this:
make: *** No rule to make target `c\:\program files (x86)\gnu arm embedded toolchain\10 2020-q4-major\lib\gcc\arm-none-eabi\10.2.1\include\stdint.h', needed by `_build/nrf52832_xxaa/nrf_log_backend_rtt.c.o'

make --version

Discussing the topic with one of our experts, we could not find what is causing this. It looks like the incremental build is broken in some way. What is the reason for running make again?
