<div dir="ltr">I had the same issue (RNGScope) and what worked for me (besides Dirk's clear explanations which I somehow missed) was to run Rcpp.package.skeleton() and compare what changed, which is exactly what Dirk mentioned above (the changes to NAMESPACE and DESCRIPTION). LinkingTo is still necessary (together with Imports) I believe (at least in my case).<br>

</div></div>Indeed, you guys have done a really good job documenting all your work. You have to forgive me, as I was only told about all these changes recently, and I did not follow all the communication as it was happening, but had to come upon it later where it wasn't always clear which document was the canonical one to read.<br>
<br>
Anyway, your suggestion did the trick for both packages. Thanks!<br>
