Trying to install thift gem after OSX El Capitan upgrade:

    $ gem install thrift     Building native extensions.  This could take a while...     ERROR:  Error installing thrift:         ERROR: Failed to build gem native extension.          /Users/foo/.rvm/rubies/ruby-2.1.4/bin/ruby -r ./siteconf20160402-32256-7dzqel.rb extconf.rb     checking for strlcpy() in string.h... yes     creating Makefile      make "DESTDIR=" clean      make "DESTDIR="     compiling binary_protocol_accelerated.c     compiling bytes.c     compiling compact_protocol.c     compact_protocol.c:442:41: error: shifting a negative signed value is undefined [-Werror,-Wshift-negative-value]         rb_exc_raise(get_protocol_exception(INT2FIX(-1), rb_str_new2(buf)));                                             ^~~~~~~~~~~

Compilation fails with compact_protocol.c:442:41: error: shifting a negative signed value is undefined [-Werror,-Wshift-negative-value]

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\"

You need to escape double quotes.

$ bundle config build.thrift "--with-cppflags=\"-D_FORTIFY_SOURCE=0 -Wno-shift-negative-value\""

$ cat ~/.bundle/config

BUNDLE_BUILD__THRIFT: --with-cppflags="-D_FORTIFY_SOURCE=0 -Wno-shift-negative-value"

Try this

gem install thrift -v '0.9.0' -- --with-cppflags='-D_FORTIFY_SOURCE=0'
