OpenCL kernel for a DE10-standard board via OpenCL SDK 18.0.0.614 Windows 7: no top.sof file

I am trying to compile OpenCL kernel for a DE10-standard board via OpenCL SDK 18.0.0.614 Windows 7 using the command:

C:\intelFPGA\18.0\hld\board\de10_standard\test\hello_world\device>aoc hello_world.cl -o bin\hello_world.aocx -board=de10_standard_sharedonly -v -report

It outputs as in the attachment.

Apparently it cannot find a top.sof file

thanks
