The toolchain is unable to build a dummy C file when building project with toolchain manager install

[fr0th]

I've been trying to build blinky using the nRF SDK from the toolchain manager with no success on windows 10. I've previously been able to build projects so I'm not entirely sure what is causing this issue.  

I'm using the nRF connect VSCode extensions, the behavior is the same with Segger embedded studio.


Things I've tried:

- Clearing the cache (ncs\SDK_VERSION\zephyr\.cache)
- Fresh install of both nRF connect & SDK/toolchain (Uninstall connect, delete ncs, .nrf-connectapps & appdata, reinstalling VSCode extensions)
- SDK versions 1.7.0, 1.7.1 & 1.6.0
- Using an older version of CMake (3.17)
- Deleting build folder & using pristine build w/ VSCode 
- Error is the same with or without nRF connect command line tools

On trying to compile the blinky example (zephyr\samples\basic\blinky) to the board  actinius_icarus_ns (i've tried others e.g thingy:91 -- no success) the following error is thrown: 

CMake Error at c:\Users\USERNAME\Documents\ncs\v1.6.0\zephyr\samples\cmake\extensions.cmake:1746 (message):

  CMakeError.log.
Call Stack (most recent call first):
  c:\Users\USERNAME\Documents\ncs\v1.6.0\zephyr\samples\CMakeLists.txt:42 (assert)

I've attached the full build log:

Just wondering if maybe someone has experienced a similar issue? There is old threads with the same error but it seems to be a solved issue & none of the fixes are working (at least for me)


Thanks

Hello, 

Looking at the log output you have attached, the path of nRF Connect SDK (NCS) is fairly long. How long is the username? Please try moving the NCS folder to e.g. C:\NCS\v1.6.0

Kind regards,
Øyvind

Thanks for the quick response Øyvind

I've just tried this now sadly no success. Same error.

Has there been any update on your Windows 10 lately? 

Likely but unsure. I'm not sure if there is a way to check.

Øyvind said:

Is this a corporate computer? Are you installing on a corporate network? We have seen that type of issues earlier, just need to verify. Do  you have a anti-virus SW running? If so, is it possible to reinstall NCS with this SW paused? To ensure that the anti-virus is not blocking anything

Personal computer, the only antivirus would be windows defender. 

Steps I've taken:

- Pause 'Real-time protection' in windows security.
- Opened nRFConnect as Administrator 
- Installed nRFConnect SDK v1.7.1 from the toolchain manager
- Select the correct toolchain + SDK in vscode (opened from toolchain manager)
- Create hello world application from sample
- Create build config + run

Same error occurs unfortunately 

Thanks

Hi Matt, 

I've discussed the issue internally based on the information you have provided. 

In order for us to find the root cause of this, you will need to add some extra print statements in the zephyr\cmake\extensions.cmake file. Based on what version of nRF Connect SDK you are working on, the line numbers differ, but the following git diff should give you an indication. The plus (+) indicates what and where you need to add.

I've tested here, and the output when building zephyr\samples\basic\blinky with the added prints above looks something like this:

If exists = 1, this indicates that zephyr/.cache is not deleted. Until we have found the issue, this will need to be deleted before every build.

From keystring you should have -Wl,--unresolved-symbols=ignore-in-object-files which we expect to prevent this error: exit.c:(.text.exit+0x2c): undefined reference to `_exit'

Let me know how this works for you.

Kind regards,

EDIT: wrong toolchain version, snipped updated

[Øyvind]

Matt, can you please try building the blinky sample in same path as NCS. 

In your command prompt, go to blinky folder:
cd c:\ncs\v1.7.1\zephyr\samples\basic\blinky and then run the following:

west build -b actinius_icarus_ns -d build

The previous comment had the path c:\Users\USERNAME\Documents\ncs\v1.7.1\, is this still on your computer? If so, please delete any other NCS folders to narrow down to one path. 

[fr0th]

Hi Øyvind,
Sorry for the late response.

I have deleted the version of ncs in Documents.

When running via a prompt the same error occurs (git bash).


One thing to note: my command prompt seems to be broken. It won't open from System32/cmd.exe  so I'll try fix this and then get back to you with results

Matt

[Øyvind]

Yes, please do. Awaiting your feedback.

[fr0th]

Øyvind, it seems this was an isolated issue on my computer that came from some corrupt(?) Python installation. 

I've since fixed it & everything is working now.

Thanks for your help.

[Øyvind]

Happy to hear!
