Hi,

This has been fixed and will be added in the next release of the Mesh SDK.

Thank you.

This bug is still present in v4.0.0 mesh SDK.

I have published a full reproduction of this on Github with an unmodified example (except to add a reference to the math library) on the stock SDK, see https://github.com/siriobalmelli/nrf_mesh_4.0.0_lm

I did try using 'set_target_link_options' but it did not work (see details in https://github.com/siriobalmelli/nrf_mesh_4.0.0_lm#reproduction)

This is breaking interoperability between automated toolchains using CMake and programmers using SES. Any help is appreciated.

Hi,

Would have thought that "Adding lm or -lm to set_target_link_options() (tried both) (see https://devzone.nordicsemi.com/f/nordic-q-a/44735/configure-math-h-lib-with-cmake-on-sdk-mesh/176144)" should have helped.

Are you trying with an unmodified example from the mesh SDK? Could you try downloading a fresh copy of the SDK and try again?
