Obscure build error "could not find package config file Zephyr-sdk"

tedhavelka66

Hello Developers,

I’ve run into a strange obscure error today, while attempting to build a Zephyr based app for the sparkfun_thing_plus_nrf9160 board. My Zephyr tools have been installed and serving my Nordic nrf based project builds for several months now. I’m using ncs version 1.6.1, which corresponds to Zephyr 2.6.0.

Python3, cmake and west are at sufficiently new versions to satisfy the early build time checks of these utilities.

So I’ve just git cloned a project which I worked on a few months ago, and which built with these same Zephyr / Nordic command line tools, across multiple hosts at that time. Today after following these same steps, when I attempt to compile my builds fail early on with these messages:

_`ted@localhost:~/projects-sandbox/zephyr-work/out-of-tree/kionix-driver-demo$ west build -b sparkfun_thing_plus_nrf9160 -p
– west build: making build dir /home/ted/projects-sandbox/zephyr-work/out-of-tree/kionix-driver-demo/build pristine

CMake Error at /home/ted/projects-sandbox/zephyr-work/out-of-tree/zephyr/cmake/verify-toolchain.cmake:75 (find_package):
Could not find a package configuration file provided by “Zephyr-sdk”
(requested version 0.13.1) with any of the following names:

Zephyr-sdkConfig.cmake
zephyr-sdk-config.cmake

Add the installation prefix of “Zephyr-sdk” to CMAKE_PREFIX_PATH or set
“Zephyr-sdk_DIR” to a directory containing one of the above files. If
“Zephyr-sdk” provides a separate development package or SDK, be sure it has
been installed.`_

Neither of the files Zephyr-sdkConfig.cmake and zephyr-sdk-config.cmake are found anywhere on my work station. Yet an older project I’ve been working in builds today and has been building for weeks without any issues.

Any idea what is going on here? Again, I had successfully git cloned and west updated this project at least five times previously, and everything worked.

I’m not finding much help for this on Nordic Devzone. Also finding scant mention of these errors in more general Google searches.

Any help appreciated on this unexpected toolchain issue!

If you move or copy this repository, you’re going to run into issues because internally the build will be referencing files that no longer “exist”. Also another thing you can do is delete your build folder completely if you haven’t yet.

Otherwise, if you are moving a repository, I recommend initializing from scratch. Just remember to commit and push any changes. (or leave your old setup unchanged until your new one is up and running)
