анаконда R - Rcpp ошибка

Question

Setup (Я использую анаконды распределенную R):

g++ (Ubuntu 5.4.0-6ubuntu1~16.04.2) 5.4.0 20160609 
R version 3.3.1 (2016-06-21) -- "Bug in Your Hair" 
Rcpp -- 0.12.5 

Минимальный пример:

library(Rcpp) 
evalCpp("1+1") 

Ошибка:

Error in dyn.load("/tmp/RtmpGI3wKi/sourcecpp_6c2722bad7ef/sourceCpp_1.so") : 
    unable to load shared object '/tmp/RtmpGI3wKi/sourcecpp_6c2722bad7ef/sourceCpp_1.so': 
    /tmp/RtmpGI3wKi/sourcecpp_6c2722bad7ef/sourceCpp_1.so: undefined symbol: _ZNKSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEE5c_strEv 

Я видел очень похожая ошибка на anaconda google groups, а также here на stackoverflow, но нет подсказок для исправления.

Answer 1

Вам нужно поговорить с хорошими людьми, которые дали вам Анаконду. В Debian и Ubuntu, все «просто работает» как надо - и можно ожидать, учитывая, что часть разработчиков использует эту платформу:

На (один из) моей рабочей станции (s) под управлением Ubuntu 16.04:

R> library(Rcpp) 
R> evalCpp("1+2") 
[1] 3 
R> 

Ditto в недавно запущенные Rocker r-base контейнера (бег тестирования Debian и вытягивать в Rcpp через apt-get):

$ docker run --rm -ti r-base /bin/bash
