Copy & paste the complete error message.
Also the piece of code to which it relates.
Tell us where that code came from - and have you modified it?

it is nrf sdk mesh (light switch code), when I compile first time,some header files are missing, then I added those header files, next these errors -
That's not the complete message - the complete message would include the file name and line number at which the problem was detected.
nrf sdk mesh
What version?
And what version of SDK?
it is nrf5_SDK_for_Mesh_v2.2.0_src, and nRF5_SDK_15.2.0_9412b96,actually it is not showing any error at particular line, C file name is ‘mesh_provisionee.c’,and showing error like
