我正在尝试在Ubuntu上安装Rcpp。以下是一些环境细节：
R version:3.4.0
g++ --version: Ubuntu 5.4.0-6ubuntu1~16.04.4
如果我有一个空白Makevars文件，可以安装RcppArmadillo但有一些关于OpenMp的警告

我将PKG_CXXFLAGS=-std=c++11添加到Makevars后，收到如下错误消息：

当我尝试在我的mac（10.11）上重新安装RcppArmadillo时，出现了同样的问题。有人能开导我吗？
答案 0 :(得分：0)
这是16.10我在这里磨练，如果你希望我明天可以在16.04重复工作：

我使用ccache并不重要。这个。只是。的工作原理。
