Answer 1

I have a solution for you! Hopefully.

Had this same problem the other day.

The problem is in the clang compiler that El Capitan comes bundled with. I'm sure it screws up other issues but this is one point that I had a lot of issues with.

Try running the following command and let me know how it goes!

gem install thrift -- --with-cppflags="-D_FORTIFY_SOURCE=0 -Wno-shift-negative-value"
