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.

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.

I was able to compile again after deleting some extra files.
I attached my log files (asset tracker build) for your review:

I was able to get a little bit forward.
Now getting a "undefined reference to _exit" error.
I opened a new case:

You can get the latest release of the GNU Arm Embedded Toolchain here and older release here. 
check out this video for a visualization of the IDE use and more: https://youtu.be/1jgImp7FBy8?t=877 
What is the command you use in terminal when trying to build?

Do you use  west build -b thingy91_nrf9160ns ? 

And do you still get the same terminal output:

Your CMakeOutput file look good the CMakeError has a build command fail that C executable Linking. 
resulting in a can not fin path.

We can continue the discussion on either case if the problem is related, i will get back to you on the topic of each case if there the problems are not related.

"You can get the latest release of the GNU Arm Embedded Toolchain here"

      I did and it did not help me.  The issue persists.

"Check out this video for a visualization of the IDE use and more: https://youtu.be/1jgImp7FBy8?t=877 "

      I did.  Thank you for the link, but it did not help me, since I tried both methods (Toolchain manager and manual) and the issue is the same.

"What is the command you use in terminal when trying to build? Do you use  west build -b thingy91_nrf9160ns ?"

     Yes.
