Compiling the BLE mesh examples

Thanks for providing inputs. I had played around and doing trial and error and now I am able to build when i moved the environment variable from user to system. It's weird but yeah after doing that I can now build. But I still see the warning on the patch that It can not find the 'patch' executable, What is the 'patch executable' for? It might be part of the culprit if it has something to do with setting up or updating configurations. I also see that Doxygen is missing but I know doxygen and i don't need it. Below is part of the log.

-- Could NOT find Doxygen (missing: DOXYGEN_EXECUTABLE)

What happens if you remove the SDK_ROOT user environment variable and then try to run the command?

hi Mttrinh, yes that is the exact files in the folder nRF5_SDK_17. It is newly downloaded sdk. I copy pasted the path when i set the user environment variable so i im sure there is no typo there. Even if I let it download the SDK. the SDK 16 is actually downloaded by the command nRF5_SDK. For testing, how can I actually set the SDK_ROOT absolute directory in the CMakeLists.txt? It looks its not looking at the environment variable.

What are your subfolders inside nRF5_SDK_17?

Is it like this in the folder?

yes I made a build directory nrf5_SDK_for_Mesh_v4.2.0\build and I am running the command here. Here is the log. I also tried to run ninja help that might give you a hint.

Did you make a build folder in the root of the Mesh SDK? Then run the command:

cmake -G Ninja ..

inside this build folder?

Can you upload the whole log after you entered that command?

Double check for typos in your path.

Hi, thanks for reaching out. I am trying to follow the documentation on nRF5 SDK for Mesh v4.2.0 > Getting started Building the mesh stack and examples. I have downloaded SDK for mesh 4.2.0 and SDK 17 ans shown in the folder structure above. I have nRF5x command line tool, CMAKE, GNU ARM, ninja installed. But when I can the command cmake -G Ninja .., I get the below warning.

as suggested in the warning, I run nRF5_SDK and so the nRF5_SDK_16.0.0_98a08e2 was also in my directory as shown on my initial post. But after that, I still get the same error. on my PC, I set the environment variable SDK_ROOT to the directory of nRF5_SDK_17 (also tried nRF5_SDK_16.0.0_98a08e2) but still I get the same error.

It looks the ninja tools doesn't know the directory of the SDK_ROOT.

There is also a tutorial in https://wiki.makerdiary.com/nrf52840-mdk/mesh/ but i'm still not able to successfully build.

Hi,

Can you walk me through step-by-step what you have done so far? What command did you run to get the above message?

Update, I updated the environment variable to nRF5_SDK_17 and new error is below.

How could I set these options?
