问题:
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!
回答1:
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.
回答2:
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.

Try deleting RcppExports.cpp and RcppExports.o and then in build options go-to "more" -> "clean and rebuild" This usually does the trick when I have similar problems
回答4:
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.

I got mine fixed by recreating the project in RStudio from GitHub in a fresh directory.
I had the same problem; happened as I was working on a markdown file irrelevant to the package, but then all of sudden package would not build with the same error:
