Question

尝试在OSX El Capitan升级后安装thift gem：

    $ gem install thrift
    Building native extensions.  This could take a while...
    ERROR:  Error installing thrift:
        ERROR: Failed to build gem native extension.

                                            ^~~~~~~~~~~

编译失败 compact_protocol.c：442：41：错误：移位负符号值未定义[-Werror，-Wshift-negative-value]

Answer 1

我有一个解决方案给你！希望。

前几天有同样的问题。

问题出在El Capitan捆绑的clang编译器中。我确定它搞砸了其他问题，但这是我遇到很多问题的一点。

尝试运行以下命令，让我知道它是怎么回事！

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

Answer 2

你需要逃避双引号。

$ 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”

Answer 3

试试这个

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

无法在OS X El Capitan上安装thrift gem

3 个答案:

$ cat~ / .bundle / config
