问题的后续行动

自从升级到Mavericks以来,我一直在与RcppArmadillo一起遇到各种各样的错误。我安装了Xcode 5.0.2和命令行工具。另外,来自Homebrew的gfortran。但我一直遇到下面的错误 -

> cppFunction("arma::mat schur(arma::mat& a, arma::mat& b) 
                       { return(a % b); }", depends="RcppArmadillo")

评论FLIBS=-lgfortran无效并导致更多错误消息 -

> cppFunction("arma::mat schur(arma::mat& a, arma::mat& b) { return(a % b); }", depends="RcppArmadillo")

提前致谢。

更新

根据以下Kevin和Dirk的回复建议,我重新安装了Rcpp,RcppArmadillo并从源代码内联并更新了FLIBS以指向实际目录。这解决了这个问题。

# Update FLIBS in ~/.R/Makevars
FLIBS=-L/usr/local/Cellar/gfortran/4.8.2/gfortran
#Re-Install from source
install.packages(c("Rcpp","RcppArmadillo","inline"),type="source")
#Restart R

答案 0 :(得分:10)

编辑:如果您是自制软件用户,则现在需要使用brew install gccgfortran不再单独提供gcc),然后您可以按照说明进行操作here要设置。


您必须手动将库符号链接到/usr/local/lib

ln -s /usr/local/Cellar/gfortran/4.8.2/gfortran/lib/libgfortran.* /usr/local/lib/

我认为brew link gfortran会处理这个问题,但显然它只对符号链接gfortran程序而不是实际的库。所以,不幸的是,你必须自己做。

(将4.8.2替换为您gfortran中使用的homebrew版本。)


或者,如果您想继续修改/usr/local/lib,可以使用

FLIBS=-L/usr/local/Cellar/gfortran/4.8.2/gfortran

在您的~/.R/Makevars文件中,因此R知道在哪里找到gfortran库。

答案 1 :(得分:1)

我只能建议你研究r-sig-mac list上的众多主题,SO上的不同答案以及rcpp-devel list上的帖子。

由于您的错误来自Fortran链接失败,因此也可以查看the standard page by Simon U.以及tools page点。 AFAIK你应该使用R的那个页面使用(较旧的)gfortran 4.2。*,但是我不是OS X用户。

2016年末编辑:我们现在在section 2.16 of the Rcpp FAQ中有更详细的说明。
