Error in Eclipse GCC when build project

[jj]

I am encountering some problem in building eclipse project following the tutorial at devzone.nordicsemi.com/.../ .

Previously I succeeded in building with another simple example project. But when I move on to use my project, it is not able to build.

I am at the step 'Enable auto discovery of symbols, include paths and compiler settings', where I configured all the properties as stated. But when I try to build project, it returns 3 errors as follow:

I did edit the makefile.windows to change the path to point to where my GNU ARM Embedded Tool is at. I also changed to the new makefile.common file which is required for SDK 12 and above.

What are the errors? And how can I fix it? Thank you.

EDIT: I managed to solve some of the above errors. But this time i got new errors of the following:

undefined reference to 'function2'
undefined reference to 'evt_write'
undefined reference to 'xxxx'
undefined reference to 'xxxx'
undefined reference to 'xxxx'

How can I fix it? Do I need to specify or set somewhere the paths to include the file where the functions are from? (The makefile under 'SRC_FILES' and 'INC_FOLDERS' did not include certain files, probably because I made use of the ble_app_template to write my project and added more files. Do I need to include the paths to these newly #include header files here or somewhere else? Please advise.)

Hi,

Looks like your makefile is not able to find the files in the SDK. The makefile uses relative paths and need the file structure used in the SDK to be kept in order to work.

Are you using the makefile for the SDK project you are using ?

In what folder have you placed the makefile?

Hi, I managed to solved some of the errors but am encountering new one. I edited the post at the bottom to include the new error. Please advise, thank you.

Yes, if you have added your own files to the project, you need to add the paths to the makefile

Where should I add the path at, under 'SRC_FILES' or 'INC_FOLDERS'? I opened the makefile in Eclipse and tried adding at 'SRC_FILES' and/or 'INC_FOLDERS' in this format: $(SDK_ROOT)/components/file1
$(SDK_ROOT)/components/file2
$(SDK_ROOT)/external/tiny-AES128 \

Here are the 3 situations I tried:

1. When I include these lines under 'SRC_FILES', it returns a fatal error 'main.c:86:42: fatal error: file1.h: No such file or directory' when I build project (after clean project).

2. When I include these lines in 'INC_FOLDERS' instead, it returns the same errors of undefined reference as stated in the question.

3. When I include these lines in both 'SRC_FILES' and 'INC_FOLDERS', it returns multiple errors such as 'arm-none-eabi-gcc: error: _build/nrf51422_xxac_file1.o: No such file or directory'

Did I do it wrongly? Or is there other area that I need to include these paths?

Sorry, the format is as follow:

$(SDK_ROOT)/components/file1 \
  $(SDK_ROOT)/components/file2 \
  $(SDK_ROOT)/components/file3 \
  $(SDK_ROOT)/components/file4 \
  $(SDK_ROOT)/external/tiny-AES128 \
