Following nrf-connect-sdk-tutorial---part-1-ncs-v1-4-0 Failure

Question

Hi, 
 This is under Linux Ubutnu 20. I am trying to evaluate the Nordic NRFConnect SDK following the tutorial at: https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-1-ncs-v1-4-0 My tree is: (after running once west build) ├── build │ ├── CMakeCache.txt │ ├── CMakeFiles │ ├── Kconfig │ ├── zephyr │ ├── zephyr_modules.txt │ └── zephyr_settings.txt ├── CMakeLists.txt ├── proj.conf ├── src │ └── main.c └── zephyr ├── arch 
 
 I already ran these inside of folder. west init west update My env vars are: 
 ZEPHYR_BASE=/NRF_CONNECT/ncs/zephyr TOOLCHAIN_ROOT=/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10 CMAKE_PREFIX_PATH=/NRF_CONNECT/ncs/zephyr TOOLCHAIN_HOME=/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10 GNUARMEMB_TOOLCHAIN_PATH=/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10 PATH=/NRF_CONNECT/gn:/NRF_CONNECT/gn:/home/marius/perl5/bin:/home/marius/usr/bin:/home/marius/.linuxbrew/bin:/home/marius/bin:/home/marius/.local/bin:/opt/SEGGER/JLink/:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/snap/bin/flutter:/usr/bin/dart:/usr/lib/jvm/java-8-openjdk-amd64/bin:/usr/lib/dart/bin:/usr/lib/jvm/java-8-openjdk-amd64/bin:/usr/lib/dart/bin CROSS_COMPILE=/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi- Then I The error is:

I went over the make files and I fix it. The tutorial is missing steps, of course... Is done in a hurry! Here are the vars I use. I installed the NRfConnect into root /NRF_CONNECT so it can be shared among several pc not depending of $HOME because moving projects along creates problems with all the build encyclopedia procedures. These are my env 
 #!/bin/bash export PATH=/NRF_CONNECT/gn:"$PATH" export ARMCLANG_TOOLCHAIN_PATH="/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10" export GNUARMEMB_TOOLCHAIN_PATH="/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10" export TOOLCHAIN_HOME="/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10" export TOOLCHAIN_ROOT="/NRF_CONNECT/ncs/zephyr" export CMAKE_PREFIX_PATH="/NRF_CONNECT/ncs/zephyr" export ZEPHYR_TOOLCHAIN_VARIANT=gnuarmemb # for the gcc-arm-none-eabi-10.3-2021.10 export CROSS_COMPILE="/NRF_CONNECT/tc/gcc-arm-none-eabi-10.3-2021.10/bin/arm-none-eabi-" export ZEPHYR_BASE="/NRF_CONNECT/ncs/zephyr" 
 That west thing works now.
