Found no calls to: 'R_registerRoutines', 'R_useDynamicSymbols'

Hi list,
I believe this has been mentioned in the old Google Group, but I’m not quite sure I understand how to fix it.

When building my package, I get a note
Found no calls to: 'R_registerRoutines', 'R_useDynamicSymbols'

I think the suggestion was to run this function once:
https://raw.githubusercontent.com/stan-dev/rstantools/master/R/init_cpp.R

I know I’m being thick, but does this mean running this function with my package loaded? Or something even simpler?
Thanks

Thank you, Ben.
This works and does create a init.cpp file. I have then checked my updated package (using Appveyor) - the problem doesn’t go away.

It only raises a NOTE (Warning):
Warning in read_symbols_from_dll(so, rarch) :
this requires ‘objdump.exe’ to be on the PATH

It is good practice to register native routines and to disable symbol
search.
See ‘Writing portable packages’ in the ‘Writing R Extensions’ manual
and all seems to work OK — but I guess this won’t pass a formal CRAN submission?

Again — apologies. I feel like I’m missing something obvious, but any ideas?..
Thanks
