This is a general packaging list; Rcpp has a dedicated list. Could you please
there, or if you cannot, on StackOverflow, or post a GitHub issue?

There are some decent tutorials out here about how to post a _minimally
verifiable complete example_, see eg
   https://stackoverflow.com/help/minimal-reproducible-example
This post would not allow to do any meaningful investigation yet.

Thanks in advance for your help,  Dirk
