Cannot build nRF5 SDK Mesh

[cdugue]

I am having errors building the examples in the latest SDK for Mesh (nrf5_SDK_for_Mesh_v0.10.0-Alpha_src). I ran cmake -DTOOLCHAIN=gccarmemb -DPLATFORM=nrf52840_xxAA .. in my build directory which appears to be working just fine. However when I do make I have errors linkings the c executable.

Any idea why?

Hi cdugue,

The specific problem seems to be that the linker can't find the objects from nrf_mesh.c, log.c and advertiser.c. Did you modify the SDK in any way? Which platform are you using? Windows, Linux or Mac OS? I tried replicating your issue by downloading a fresh copy of the SDK and building it in the following way, but it didn't return any errors for me:

wget www.nordicsemi.com/.../126781 -O mesh_sdk.zip
unzip mesh_sdk.zip -d mesh_sdk
mkdir mesh_sdk/build
cd mesh_sdk/build
cmake -DTOOLCHAIN=gccarmemb -DPLATFORM=nrf52840_xxAA ..
make

Output from CMake:

Hope this helps,

Hi Thomas,

Thanks for your help. I followed your steps on my mac and it worked just fine, I was able to build the files.
