[Rcpp-devel] Can not install Rcpp on Mac OS X 10.9.5

[Kevin Ushey]

Your error:

Error in dyn.load(file, DLLpath = DLLpath, ...) :
  unable to load shared object
'/Users/py/Library/R/3.2/library/Rcpp/libs/Rcpp.so':
  dlopen(/Users/py/Library/R/3.2/library/Rcpp/libs/Rcpp.so, 6): Symbol
not found: __ZNSoD0Ev


says some (mangled) symbol named `__ZNSoD0Ev` could not be found. Using the
online demangling tool at http://demangler.com/, I see this symbol is:

_std::basic_ostream<char, std::char_traits<char> >::~basic_ostream()


which should be provided by your C++ standard library.

Given that you're using `g++` on OS X, I'm assuming you installed gcc from
macports or something like that, but either that was provided without a
standard library (libstdc++), or it's distributed in such a way that
libstdc++ isn't located on its default library search path.

So, you should either:

1. Figure out where you can get libstdc++ for the g++ compiler you've
obtained, or
2. Just use Apple's command line tools (clang etc) as that will 'just work'.
