error in dyn.load in Rcpp package in mac

Question

I have a problem in loading compiled object Rcpp compiled object. I am compiling RcppSMC package from source. I

Error in dyn.load("mylib.so") : 
  unable to load shared object '/Users/avi/softwares/RcppSMC/src/mylib.so': 
  dlopen(/Users/avi/softwares/RcppSMC/src/mylib.so, 6): Symbol not found: __ZNSoD0Ev
  Referenced from: /Users/avi/softwares/RcppSMC/src/mylib.so
  Expected in: flat namespace
 in /Users/avi/softwares/RcppSMC/src/mylib.so 

I am using clang for compiling with following verson. I think there is some compiling problem because if I download the mac os binary from CRAN dyn.load works.

installing to /Users/avi/Library/R/3.0/library/RcppSMC/libs

This is weird problem because sourceCpp is working in the machine.

Answer 1

If you're trying to install a package that links to Rcpp from source, you probably also need to install Rcpp from source.

Assuming that you're using OS X Mavericks, there have been similar posts around StackOverflow with similar problems.

Answer 2

A colleague of mine got the same issue.

We tried every possible solution we found on the Internet.

We end up concluding that it was the new version of Mac (Mojave) that caused these types of issues.

He downgraded to Sierra and reinstalled everything. That solved his problem.
