Someting more fundamental may be out of line as that is _of course_ part of
Rcpp and provided. Maybe you don't importFrom(Rcpp, evalCpp) in NAMESPACE or
declare the dyn.lib wrong.

No, just check CRAN -- hundreds of Rcpp packages use roxygen.

In my ?stupid? (minimal) project, my namespace looks as follows:

useDynLib(StupidRCPP, .registration=TRUE)
exportPattern("^[[:alpha:]]+")
importFrom(Rcpp, evalCpp)

In my main project I include Rcpp in an import() statement in NAMESPACE.

One thing I?m noticing with the minimal project is that I can build it without errors and access functions from the package but  devtools::check() reports syntax errors?though these errors appear to be from an old version of the code (it has been quite a headache manually deleting all of the files in .Rcheck, RprojUser, and the Rtmp? folders.
