Failed to manually build blinky example

[mraposo1]

Had tried to build it from the IDE before.  Couldn't do it.
Tried to build manually, got exactly the same error I was getting in the IDE.

Hi Mario,

What version of ncs do you have?
What version of cmake do you have?
Can you build other example projects?

I see that you have a dot "." in you path. C:/Users/mario.raposo/... Try to change the "." to a underscore "_" and se if you still have the same build errors. 

The error:

CMake Error at ../../../cmake/extensions.cmake:1557 (message):

is the following 

 check_if_directory_is_writeable(${test_user_dir} ok)
      if(${ok})
        # The directory is write-able
        set(user_dir ${test_user_dir})
        break()
      else()                          // This is line 1557
        # The directory was not writeable, keep looking for a suitable
        # directory
      endif()

Regards,
Joathan

Changed my path to \Nordic and I get the same error when I do a manual build:

Hi Mario,

You can follow the latest NCS versions on our Github here, it is not recommended to work on master unless you absolutely needs the latest fixes/features. Check out latest tag on Github to work on a stable version. Or use the nRF connect for desktop and Toolchain manager to get the latest recommended version witch is v1.3.1 at the moment.


There is a previous Devzone ticket where the solution is to delete the CMake cache.
"Can you try to delete ~/Library/Caches/zephyr before building and see if that helps?"


Have you followed the instructions here, https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#gs-installing 

Do you have the nrf Command line tools?
See this section for instructions on how to set up command line build environment.



If none of the above helps can you provide the CMakeError.log file ?

Regards,
Jonathan

There is a previous Devzone ticket where the solution is to delete the CMake cache.
"Can you try to delete ~/Library/Caches/zephyr before building and see if that helps?"

   A: I've tried that before, but first, there are only these Library folders on my installation:



   None of them have a .cache folder on it.
   There is a cache folder at C:\Nordic\ncs\zephyr\.cache, which I deleted but it did not help me

Have you followed the instructions here, https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_installing.html#gs-installing 

    Yes I did.

Do you have the nrf Command line tools?
See this section for instructions on how to set up command line build environment.

    I'll look at it, but my goal is to be able to build and debug at real time (breakpoints, etc...)

If none of the above helps can you provide the CMakeError.log file ?

    I can't. At this point I am stuck.
    The Open IDE option on the Toolchain manager is not there anymore.
    I tried to remove and re-install, delete the installation folder and re-install, but now the option is gone.
