[R-pkg-devel] Rcpp: cannot find R_ext/Callbacks.h under winbuilders R-devel
Dear package developers and affiliated people, I just noted a problem with an Rcpp-based package (cannot find R_ext/Callbacks.h): https://win-builder.r-project.org/S0C6dP4J5NLU/00install.out I admit that I don't know if it is a problem in Rcpp, R-devel or in the Rcpp example from RStudio. To reproduce in RStudio, just 1. create a new Rcpp sample, 2. change the email in DESCRIPTION into something meaningful (I forgot that part when I tried it first) 3. submit to r-devel (!) on CRAN's winbuilder I appreciate any guidance on this (since my own package shows the same error). Best wishes, Matthias
