Error installing RcppArmadillo

[IsabelFE]

Hello,

I am new to R and I having some issues installing packages. I am trying to install RcppArmadillo and I am getting the next error:

install.packages("RcppArmadillo")

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: *** [RcppArmadillo.so] Error 1
ERROR: compilation failed for package 'RcppArmadillo'

• removing '/Library/Frameworks/R.framework/Versions/3.2/Resources/library/RcppArmadillo'

Could you please help me?

Some info: I use OSX el Capitan 10.11.
R version 3.2.3 (2015-12-10) -- "Wooden Christmas-Tree"
Platform: x86_64-apple-darwin13.4.0 (64-bit)
R Studio Version 0.99.489

Thanks a lot,

Isabel

The error is right in front of you: you need to install the Fortran compiler or library (as we need to link to LAPACK which in turn requires Fortran)

ld: library not found for -lgfortran

Please see the OS X help for R -- there is a list or google it -- on this. I don't have an OS X machine, but I understand this be a FAQ. Worst case please subscribe to rcpp-devel and ask there.

You need gfortran v4.8; see here:

http://www.thecoatlessprofessor.com/programming/rcpp-rcpparmadillo-and-os-x-mavericks-lgfortran-and-lquadmath-error/

which is still relevant for El Capitan. Open terminal and run

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 /

Yep, I just poked around on StackOverflow and here is one answer from there. Thanks to @kthohr for the link from @coatless.

It works to some people if you install the Dev version:

install.packages("https://cran.r-project.org/src/contrib/Archive/RcppArmadillo/RcppArmadillo_0.9.900.3.0.tar.gz", repos=NULL, type="source")

I am sorry but what value does that message add? We had three+ more releases since so 0.9.900.3.0 is outdated.
