解决方案

我有你的解决方案！希望如此。

前些日子有同样的问题。

问题出在clang编译器中，El Capitan捆绑在一起。我敢肯定，它解决了其他问题，但这是我遇到很多问题的一点。

请尝试运行以下命令并让我知道它是怎么回事！

  gem install thrift  -  --with-cppflags = \-D_FORTIFY_SOURCE = 0 -Wno-shift-negative-值\
  

Trying to install thift gem after OSX El Capitan upgrade:

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

解决方案

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\"
