I'm currently on a Mac running El Cap 10.11.6 attempting to install the 'robustbase' package in R Studio and am encountering the following error:

    ld: warning: directory not found for option '-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0'
    ld: warning: directory not found for option '-L/usr/local/gfortran/lib'
    ld: warning: directory not found for option '-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0'
    ld: warning: directory not found for option '-L/usr/local/gfortran/lib'
    ld: library not found for -lgfortran
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    make: *** [robustbase.so] Error 1
    ERROR: compilation failed for package ‘robustbase’
    * removing ‘/Library/Frameworks/R.framework/Versions/3.4/Resources/library/robustbase’

I have looked around to find possible solutions and saw in this thread that I may be needing to modify the R/makevars file.

Is this the proper solution? If so, where do I modify this file, in my terminal? This is beyond my basic knowledge of R and code so any help is appreciated.

Let me know if any additional information would be of help!

You seem to be running an outdated version of R. You should install the latest version. What follows is only valid for the latest version of R.

You don't seem to have the Fortran compiler installed. You can get it from CRAN on this page tools. You might also need to install the clang6 compiler available on the same page.

If you do that you should add this

/usr/local/clang6/bin

to the start of your PATH. You should check that /usr/local/bin is in your path to make the gfortran compiler accessible.

You should also add these lines to your ~/.R/Makevars.

CC=/usr/local/clang6/bin/clang
CXX=/usr/local/clang6/bin/clang++
LDFLAGS =-L/usr/local/clang6/lib

In macOS 15 Catalina, I was getting a similar error: ld: warning: directory not found for option '-L/usr/local/gfortran/lib/gcc/x86_64-apple-darwin15/6.1.0'. And that was because I copy-pasted .R/Makevars from another installation.

The fix for my macOS Catalina I used this Makevars configuration:

XCBASE=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk
LLVMBASE=/usr/local/opt/llvm
GETTEXT=/usr/local/opt/gettext
GCCBASE=/usr/local/opt/gcc
LIBOMP=/usr/local/opt/libomp

# brew gcc: start
CC=$(LLVMBASE)/bin/clang
CXX=$(LLVMBASE)/bin/clang++
CXX11=$(LLVMBASE)/bin/clang++
CXX14=$(LLVMBASE)/bin/clang++
CXX17=$(LLVMBASE)/bin/clang++
CXX1X=$(LLVMBASE)/bin/clang++
# brew gcc: end

CPPFLAGS=-isystem "$(LLVMBASE)/include" -isysroot "$(XCBASE)"
LDFLAGS=-L"$(LLVMBASE)/lib" -L"$(GETTEXT)/lib" --sysroot="$(XCBASE)"

FC=$(GCCBASE)/bin/gfortran
F77=$(GCCBASE)/bin/gfortran

FLIBS=-L$(GCCBASE)/lib/gcc/9/ -lm

With this Makevars I have been able to build from source these R packages: data.table, sf, devtools, RcppArmadillo, psych, tmvnsim, gower, and many others.
