warning: attempt to assign the value 'y' to the undefined symbol

RE: warning: attempt to assign the value 'y' to the undefined symbol

I'm sorry for all the hassle. We are aware of all the troubles regarding installing NCS on Mac, and are currently working it improving it (making the Toolchain Manager more stable and updating the documentation).

The issues you're seeing might be due to conflicts with the Getting Started Assistant. From an earlier discussion I had with a developer I was told that it is important to either use the Toolchain Manager 100% or the Getting Started Assistant 100%, and not mix them at all. Hopefully we'll be able to fix this soon.

Hopefully build-ncs-application-firmware-images-using-docker will help you resolve it. If not I'll try to help you with reverting all the steps from Getting Started Assistant.

Best regards,

Simon

Was just wondering if the toolchain could not just run in a preconfigured docker container and google led me to https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/build-ncs-application-firmware-images-using-docker

I wonder why I did not run into this earlier.
There are some urgent things on my desk right now, but I will give this a try later.

Thanks for the effort you guys put in!

I updated the toolchain manager to 0.9.1 yesterday.

I reinstalled the Toolchain.

Same behaviour.

Maybe something is messed up cause i went with the "getting started assistant" first, then realized the toolchain manager is a thing. Not sure if that could be messing something up, but also not sure how to revert all the things done during the getting started steps.

Here is the output and what I did (first line is setup from toolchain manager I assume):

RE: warning: attempt to assign the value 'y' to the undefined symbol

Could you try to update to the latest Toolchain Manager (TM):

I got a colleague with a Mac to test the steps you mentioned (using Toolchain Manager v0.9.1)

Copy ncs\v1.4.2\nrf\samples\bluetooth\peripheral_lbs\ to any folder (e.g. ~/temp/peripheral_lbs/)
open terminal in new folder
- Not the terminal from the Toolchain Manager
source /opt/nordic/ncs/v1.4.2/zephyr/zephyr-env.sh
west build -b nrf52840dk_nrf52840

and it built without problems.

Try to update the TM and see if it works then. I not, please get back to me.

Building the example from CLI this way worked, if I build inside the samples folders.

On trying to build from custom folders (copies of samples), west does not know how to `build`.

If the same thing happens when you build the peripheral_lbs inside its initial location (nrf\samples\bluetooth\peripheral_lbs\CMakeLists.txt) that might signify that there is something wrong with your setup, the Toochain Manager should set up everything for you and it should build out-of-the-box.

Let's see what happens if you use the command prompt that comes with the Toolchain Manager. Could you try the following:

Open the command prompt through the Toolchain Manager (don't use v1.4.99-dev1 as in the image below, use v1.4.2 instead)

Redirect to /opt/nordic/ncs/v1.4.2/nrf/samples/bluetooth/peripheral_lbs and build the sample
- Don't set the Zephyr Base or run zephyr\zephyr-env.cmd. The Toolchain Manager will set up everything for you.

If it fails, could you upload the build log?

LarsH — Tue, 09 Feb 2021 18:57:28 GMT

actually, the same happens when i try to build the peripheral_lbs project inside the samples folder. And for other projects, like peripheral_uart or peripheral_hids_keyboard (and probably more).

RE: warning: attempt to assign the value 'y' to the undefined symbol

LarsH — Tue, 09 Feb 2021 18:07:39 GMT

Thanks for giving it a try. Here are my steps, i just recreated them:

Copy ncs\v1.4.2\nrf\samples\bluetooth\peripheral_lbs\ to any folder (e.g. ~/temp/peripheral_lbs/)
open terminal in new folder
source /opt/nordic/ncs/v1.4.2/zephyr/zephyr-env.sh
west build -b nrf52840dk_nrf52840

I used the Toolchain Manager to install NCS (not sure what NCS stands for tho) on MacOS and succesfully built applications in Segger Studio using nRF Connect SDK v1.4.2. I only tried sample projects that were selected from within Segger Studio and never from custom folders.

However, I prefer to use CLI tools, as the rest of our projects are just plain CMake porjects.

RE: warning: attempt to assign the value 'y' to the undefined symbol

Simon — Tue, 09 Feb 2021 17:45:17 GMT

I took a look at your other case: https://devzone.nordicsemi.com/f/nordic-q-a/71461/basic-project-setup---where-to-find-information

If you're struggling with installing NCS I would highly recommend you to use Toolchain Manager, not the Getting Started Assistant app (GSA). You install it by simply pressing a button, and everything should work out of the box. It should work fine for Windows, but is not 100% stable for MacOS yet. If you're using Linux, you need to use the GSA.

Best regards,

Simon

I was not able to reproduce the warning message. I did the following:

Placed ncs\v1.4.2\nrf\samples\bluetooth\peripheral_lbs\src\main.c into C:\Nordic\samples
Opened the command line in C:\Nordic\samples\peripheral_lbs
Set the zephyr base: set ZEPHYR_BASE=C:\Users\Simon\ncs\v1.4.0\zephyr
Built the sample: west build -b nrf52840dk_nrf52840 -d build_52840dk_no1

I did not get the warning message you mentioned.

Could you provide details steps on how to reproduce this?

Best regards,

Simon
