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

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):

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

    I'm not able to reproduce on my side, building zephyr\samples\basic\blinky for actinius_icarus_ns. What version of Windows, VS Code extension, and Toolchain Manager are you running? Do you get the same when building with west in command line? Are you opening VS code from the Toolchain Manager?

    In VS Code please run the "nRF Connect: Generate support information" command (Ctrl + Shift + P).

    Kind regards,
    Øyvind

    Sure thing,

    nRF Connect v3.7.1
    Toolchain manager: 0.10.0

    I'm opening vscode from the toolchain manager and I do get the same error when building from west.

    I've hidden some things from the output but this is what it produces

    EDIT: Reinstalled extensions



    Thanks,

    EDIT: 

    Weirdly, and I don't know if this is related. In the output tab in VSCode (terminal pane) under C/C++ Configuration warnings this error is present:

    [9/11/2021, 2:13:04 pm] Unable to resolve configuration with compilerPath "c:\ncs\v1.6.0\zephyr\samples\basic\blinky\${nrf-connect.toolchain:1.7.0}\opt\bin\arm-none-eabi-gcc.exe".  Using "cl.exe" instead.

    Hello again, and thanks for providing this information. The VS Code team do not understand why you are getting the last message/warning, as it seems to use 1.7.0. When shortening the path, as I suggested, how did you do so? 

    Could you please provide the CmakeError.log? " Assertion failed: The toolchain is unable to build a dummy C file. See CMakeError.log."
