Installation issue: OS X "-lgfortran" and "-lquadmath" errors

[DrK-Lo]

Hi Florian,
I've been using your bigsnpr package in a class I teach, and some of the students were having issues installing. One of the errors was this:

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)
make: *** [bigstatsr.so] Error 1
ERROR: compilation failed for package ‘bigstatsr’

• removing ‘/Library/Frameworks/R.framework/Versions/3.3/Resources/library/bigstatsr’
  Installation failed: Command failed (1)

Hello Katie,

Are you sure they all have the command line tools installed on their Mac?
They just need to run xcode-select --install.

Also see this blog post.

Command line tools are installed, but from the post sounds like the problem is deeper. Thanks!

If you manage to solve these installation problems, please report your solution(s) there.
It will help others, thanks.

I could confirm that following the directions in the aforementioned Blog post would solve this problem with MacOS Sierra.
