nRF5 SDK build error with GCC under windows

[RezaNZ]

Hello,

I am using SDK5 for my code that builds successfully under Linux, but not under windows.

The error occurs in the SDK, not in the application. I am wondering what modifications are needed to migrate from Linux to Windows, apart from editing MakeFile.Windows?

The details are as follow:

build system: Makefile + GNU tools ARM embedded, version 7.3.1

Windows 7 vs UBUNTU

MakeFile.Windows:

GNU_INSTALL_ROOT := C:/Program Files (x86)/GNU Tools ARM Embedded/7 2018-q2-update/bin/
GNU_VERSION := 7.3.1 
GNU_PREFIX := arm-none-eabi

The error shown:

Building nrf52832
C:/Aries/Ares-NRF52/nrf52832/makefile.mak:162: *** empty variable name. Stop.

The mentioned line (MakeFile.mak: 162):

$(foreach target, $(TARGETS), $(call define_target, $(target)))

And the macro that is called in the above line:

# $1 target name
define define_target
$(eval OUTPUT_FILE := $(OUTPUT_DIRECTORY)/$(strip $(1))) \
$(eval $(1): $(OUTPUT_FILE).out $(OUTPUT_FILE).hex $(OUTPUT_FILE).bin \
           ; @echo DONE $(strip $(1))) \
$(call prepare_build, $(1), $(OUTPUT_FILE).inc, $(OUTPUT_FILE).out)
endef

this macro and subsequent ones look fine, considering that it builds successfully under Linux with the same makefile and GCC version.

I have read and applied all relevant guides and I don't see what is the issue.

As for the last comment, my windows GCC builds our other projects successfully. So, the problem is not in its installation.

Thank you for any idea

Hi,

Did you create your own makefile instead of using the ones we provide with the SDK? This seems like more of a GCC question than a Nordic question, but if you upload your makefil I can see if i can help you out.

Have you checked the files for linux specific characters, or made sure there is no whitespaces, etc. that should not be there?

Best regards,
Jørgen

[RezaNZ]

We have our own makefile that uses the SDK's makefiles, specifically MakeFile.common (SDK dir\components\toolchain\gcc\), where the error occurs. 

I am not sure about Linux-specific characters. I only considered / and \. Do you possibly have any reference that can forward me?

I can upload my MakeFile, if it helps and if you please tell me how to upload it.

[Jørgen Holmefjord]

You can upload files in your comments from the 'Insert' menu. If you do not want the file to be shared in public, please let me know. I can then convert the case into a private case.

Here are my Makefiles. For some reason, makefile.mak and MakeFile.wondows fail to upload, so I renamed them to makefile-mak.txt and makefile-windows.txt to be able to upload them.

Thank you very much for your help

Your makefile is shorter than line 162. Did you change it? Where have you defined the variables PROJ_DIR and VARIANT on line 3?

OUTPUT_DIRECTORY := $(PROJ_DIR)/obj/$(VARIANT)
