Question

设置（我使用anaconda分布式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

最小例子：

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

错误：

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

我在堆栈溢出的anaconda google groups和here上看到了非常类似的错误，但没有提供补救措施。

你将不得不与给你Anaconda的好人交谈。在Debian和Ubuntu上，所有内容都“应该正常” - 并且可以预期，因为部分开发人员使用该平台：

在运行Ubuntu 16.04的我的工作站上（其中一个）：

在一个刚刚启动的Rocker r-base容器中运行（运行Debian测试并通过apt-get拉入Rcpp）：
