That’s what I meant when I said: “I re-run compileAttributes”.

Dirk, I think we’re talking past each other. Can you please try the following steps exactly:

1. untag the myPackage-0.1-1.tar.gz that I attached in my previous message
2. cd myPackage
3. rm src/RcppExport.c R/RcppExport.c
4. Rscript -e ‘Rcpp::compileAttributes()’
5. check whether duplicate definitions of “rcpp_hello_world” appear in the generated RcppExport files. I get what’s in the attached 0.1-1 tar file: one copy of rcpp_hello_world with no parameters and one with a single parameter “foo”.
