Hi,

I am following all the steps on this page: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/getting_started/installing.html to manually install the nRF Connect SDK on my ubuntu based laptop. The details of my system are as follows:

uname -a

Linux laptop 5.19.0-35-generic #36~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Feb 17 15:17:25 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

I have extracted the file zephyr-sdk-0.15.2_linux-x86_64.tar.gz to my home directory. I have run the setup script and I have set the environment variables:

export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb

export GNUARMEMB_TOOLCHAIN_PATH=~/zephyr-sdk-0.15.2

I then try to build my target using the nrfconnect sample matter app in the connected home over ip repo: https://github.com/project-chip/connectedhomeip/blob/master/examples/lock-app/nrfconnect/README.md

I first remove the build directory as I have found that previous environment variables are set there and then I run the west build -b build_target

rm -rf build/

west build -b nrf52840dk_nrf52840

Unfortunately the build fails with the error "Zephyr was unable to find the toolchain.". I have followed the step carefully (and several times) so I suspect that the problem is because of the toolchain path that I am using.

Can someone help me and suggest the proper full path for the toolchain. Within the ~/zephyr-sdk-0.15.2 directory I have many sub directories that look to be platform specific e.g.

aarch64-zephyr-elf, arc64-zephyr-elf, arc-zephyr-elf, x86_64-zephyr-elf, etc. I have attached my directory structure

What should I use for export GNUARMEMB_TOOLCHAIN_PATH?

Many thanks

Ivo

Hello

Any reason you're not following the "installing automatically" guide?

I would really recommend doing that.

Best regards,

Einar

Hi,

I tried installing automatically but I am still having some problems.

Not when I try to build I get a problem with the python executable in the NCS toolchain folder.

./python3: error while loading shared libraries: libpython3.8.so.1.0: cannot open shared object file: No such file or directory

I have python3 installed so why I wonder why the toolchain isnt is using the local version?

And if I follow this guide: https://github.com/project-chip/connectedhomeip/blob/master/examples/lock-app/nrfconnect/README.md

What toochain dir path should I use for the following?

export GNUARMEMB_TOOLCHAIN_PATH=toolchain-dir

Finally, my VSCode nrfconnect extension is hanging when I try to create a build configuration

Any ideas?

Many thanks

Ivo

Can you please share the full error log output for this?

I got it fixed by reinstalling the entire tool chain

Glad to hear the issue was fixed.
