Rcpp::compileAttributes() Error

Question

I am trying to compile a small package that I've made. This package uses Rcpp and RcppArmadillo. Everything was working well until I updated my mac to Sierra (version 10.12.5). I have now the following error message when building the package from Rstudio (version 1.0.143):

Error in Rcpp::compileAttributes() : 
Evaluation error: no native symbols were extracted.
Calls: source ... withVisible -> eval -> eval -> <Anonymous> -> .Call
Execution halted

Any idea what this is and how it can be fixed?

Thank you very much!

Answer 1

Try

tools::package_native_routine_registration_skeleton(".", character_only = FALSE)

The unintuitive character_only = FALSE is necessary if you are not calling this for the first time.

I copied this answer from kbenoit at https://github.com/kbenoit/quanteda/issues/846. This worked for me when I had a similar problem.

Answer 2

I have the same error after renaming the package.

After removing the compiled object files under src/ such as xxx.o and xxx.so, it works again.

Answer 3

In my case this happens when there is a problem with the NAMESPACE file, or when NAMESPACE is missing. There is a catch-22. Roxygen2 wont overwrite your NAMESPACE file, but if you delete it and run roxygen to generate the NAMESPACE file, compileAttributes is called, but hangs because the NAMESPACE file is missing.
