Question

我最近安装了R 3.1.3。我正在使用带有Yosemite系统的Mac，而我的Xcode是6.2版本。

在使用sourceCpp（＆＃34; try.cpp＆＃34;）获取CPP文件后，出现以下错误。我的try.cpp文件有

#include <RcppArmadillo.h>
#include <math.h>

R

中的错误如下

ld: warning: directory not found for option '-L/usr/local/lib/gcc/x86_64-apple-darwin13.0.0/4.8.2'
ld: library not found for -lquadmath
clang: error: linker command failed with exit code 1 (use -v to see invocation)

WARNING: The tools required to build C++ code for R were not found.

Please install Command Line Tools for XCode (or equivalent).

我已经为Xcode安装了命令行工具，我的gfortran版本是4.9.0 但是当我输入

gfortran --version

它有以下错误：

 gfortran: warning: couldn’t understand kern.osversion ‘14.1.0

当我使用R 3.1.2时，我之前没遇到过这个问题！

感谢任何帮助！

如果您遇到同样的问题，请输入

curl -O http://r.research.att.com/libs/gfortran-4.8.2-darwin13.tar.bz2
sudo tar fvxz gfortran-4.8.2-darwin13.tar.bz2 -C /

终端上的

和sourceCpp可以顺利运行。
