Nanopb build error

[kalbani]

I was working and testing protobuf using the zephyr example (nanopb) on 1.9.1 SDK. but in build step fails with this error: ModuleNotFoundError: No module named 'google':

and I check the same python that used in this build to see if the Module are installed. and I found the google Module. I don't know whats wrong here.

any one can help please ^_^ 

Thanks.

Hi kalbani 

Thank you for raising this.

A fix has been prepared here: https://github.com/nrfconnect/sdk-nrf/pull/9100

but it awaits a new Toolchain build which updates the included nanopb to 0.4.6 and included the pip package `protobuf`.

If you do not have time to wait for a new toolchain build, then you may manually update your existing NCS Toolchain.

Steps to follow:

• Download `nanopb-0.4.6` from here: https://jpa.kapsi.fi/nanopb/download/nanopb-0.4.6-windows-x86.zip (windows version)
• Extract into the toolchain folder, `<path-ncs-toolchain>/toolchains/v2.x.x/nanopb`
  • You may backup / rename the existing folder as `nanopb-0.4.4`
• Install the pip package protobuf for the python in NCS Toolchain:
  `<path-ncs-toolchain>/toolchains/v2.x.x/opt/bin/python -mpip install protobuf`
• Fetch the commits in https://github.com/nrfconnect/sdk-nrf/pull/9100 and apply in your `sdk-nrf` repository.

Replace the `x.x` with the exact NCS Toolchain you have installed in your system.

Best regards

Hello Torsten Rasmussen 

all things work fine with me now. However, this steps work only in sdk v2.0.0 and above and my project are in sdk v1.9.1. Is there solution for sdk v1.9.1 ?

Hello,

Have you tried to just apply the changes manually? Looking at the NcsConfig.cmake I don't see much difference between v1.9.x and v2.1.x.

https://github.com/nrfconnect/sdk-nrf/blob/v1.9.2/share/ncs-package/cmake/NcsConfig.cmake
