RcppArmadillo:在Mac上安装软件包时出错

Question

我有一个R包,我试图在MAC OS(约塞米蒂)上安装,我收到链接器问题.这是我得到的错误

clang++ -dynamiclib -Wl,-headerpad_max_install_names -undefined dynamic_lookup -single_module -multiply_defined suppress -L/Library/Frameworks/R.framework/Resources/lib -L/usr/local/lib -o File1.so File2.o File3.o File4.o RcppExports.o Utils.o -L/Library/Frameworks/R.framework/Resources/lib -lRlapack -L/Library/Frameworks/R.framework/Resources/lib -lRblas -L/usr/local/lib/gcc/x86_64-apple-darwin13.0.0/4.8.2 -lgfortran -lquadmath -lm -F/Library/Frameworks/R.framework/.. -framework R -Wl,-framework -Wl,CoreFoundation

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 -lgfortran
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [mypackage.so] Error 1
ERROR: compilation failed for package ‘mypackage’

我的Makevars文件包含:

PKG_LIBS = $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)

在DESCRIPTION,我有:

Depends:
    R (>= 3.2.0),
    Rcpp,
    RcppArmadillo
LinkingTo: Rcpp, RcppArmadillo

在R/help.R,我有:

#' @importFrom Rcpp evalCpp
#' @import RcppArmadillo
#' @useDynLib mypackage
NULL

这与此问题不是同一个问题,因为我已将Armadillo依赖项包含在其他.cpp文件所隐藏的头文件中:

#include <iostream>
#include <algorithm>
#include <cmath>
#include <Rmath.h>
#include <RcppArmadillo.h>

// [[Rcpp::depends(RcppArmadillo)]]

我错过了什么吗？是否应该修改makefile？

Answer 1

修正:

轻松修复

打开Terminal来自/Applications/Utilities/

输入以下内容 Terminal

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 /

更耗时:

使用homebrew或macports抓取gcc哪个包含gfortran.改变~/.R/Makevars.(有关gfortran安装的详细信息,请参阅openmp帖子homebrew.)
