Cannot build projects in SES; 'entropy.c' & ctr_drgb.c' fatal errors

[jktair]

Hi Devzone,

I am struggling to build projects in SES. I am getting "fatal errors" when I try to build applications and samples. See following output from SES (asset_tracker build):

1> Compiling ‘entropy.c’
2> Compiling ‘ctr_drbg.c’

I am using the Nordic Semi. version of SES.
I have used the "Getting Started Assistant" to set up my toolchain. I have re-cloned the nRF Connect SDK using the commands mentioned in the Getting Started Assistant. I have also installed the modules mentioned in the assistant.
I am using "ncs_tag" = v1.0.0

Thanks in advance.

Regards, 
Jesper.

Hi, 

Just to make sure, did you also run "west update" after changing the tag?

Please run these commands and build the code again.

git checkout v1.0.0
west update

Hi,

Yes, I did run "west update".
I just tried to run the commands again, but with no luck. I am still getting the same errors when I build.

Hi,

I deleted the nsc folder, and performed the commands as per instructions in Section 2. 
I had no issues cloning the nRF Connect SDK, nor any when using a tagged version (v1.0.0).
But when I tried to install the required modules for Zephyr, I get the following error:

Collecting hub==2.0 (from -r zephyr\scripts\requirements.txt (line 10))
  ERROR: Could not find a version that satisfies the requirement hub==2.0 (from -r zephyr\scripts\requirements.txt (line 10)) (from versions: 0.0.1, 0.1.0, 0.1.1, 0.1.2, 0.1.3, 0.1.4, 0.1.5, 0.1.6, 0.2, 0.2.0.1, 0.2.0.3, 0.2.0.4)
ERROR: No matching distribution found for hub==2.0 (from -r zephyr\scripts\requirements.txt (line 10))

When trying to install hub==2.0 manually, I get the same error. 
By the looks of it, there seems to be no version "2.0" for hub. The "closest" version is "0.2".
Should I try to install this version (v0.2) manually?

The requirements for "nrf" and "mcuboot" installed with no errors.

Edit: I have not tried the tutorial mentioned. Will do so soon.

Hi Jesper, 

Please see Bjørn Kvaale's suggestion in this post:

changing hub == 2.0 to git-spindle == 2.0

Hi Amanda,

I am able to build the project now, which is great :)
I did as suggested, and changed the "requirements.txt" file. I was then able to complete the installation with no further issues. 

I also didn't have any issues flashing my merged.hex to the DK. However, I don't seem to be able to get a connection. I am running asset_tracker, in an attempt to add the DK to my nRF Cloud, but only LED 3 blinks. Should I open a new thread on this topic? 

Nevertheless, thank you for your help :)

Oh no... I am getting new errors when trying to build the at_client sample, see below...

What could be the cause this time?

I performed a reboot of my pc, and I have also changed the location of my build folder (shortening the path to the build folder). I am now able to successfully build both asset_tracker and at_client.

I hope that was it, and that I can continue to build in the future.
