How to compile project with include and src folders

[Xander To]

Hi nRF Team,

We are using nRF52832 with nRF5_SDK_17.1.0_ddde560. Our project is growing bigger and we need to separate the header and source files into different folder for better management. We wanted to split .h files into include folder and .c files into src folder. However, doing so will throw this error when we compile the project

make: *** No rule to make target '../../../custom_file.c', needed by '_build/nrf52832_xxaa/custom_file.c.o'.  Stop.
make: *** Waiting for unfinished jobs....

I believe we need to modify a file to allow the compile to know this change of path. I understand that the target should be

'../../../src/custom_file.c'

instead of 

'../../../custom_file.c'

However, I don't know where to change this. Can you please show me how to do so?

I already updated the Makefile to something like 

$(PROJ_DIR)/src/custom_file.c \

Best regards,

Xander

Hi Xander,

Are you using make and ARM gcc to build your project? If so, you should only need to make the change you mentioned.

Could you please retry after clearing all existing build artifacts?

Best regards,

Hi Hieu,

Yes I use make and arm gcc. Which build artifacts I should remove? I have deleletd all files in armgcc/_build folder but it doesn't solve the issue

Best regards,

Hi Xander,

Quick shot in the dark, can you try deleting the _build directory entirely?

$(PROJ_DIR)/src/custom_file.c \

should have been all you need.

Given your output log states

 

"'../../../custom_file.c'"

 

it seems like

 

$(PROJ_DIR)/custom_file.c \ 

is what it tried to do.

I very briefly tested the in an existing application with identical folder structure to your opening post (src/ and include/ directories added to put the files in there), and the only addition I needed was   $(PROJ_DIR)/src/custom_file.c \ under the SRC_FILES += \ list.

Hi Johnny,

Thank you for your help. It actually fixed the problem by deleting the _build folder entirely. 

Best regards,
