ruby - 节俭 ruby

Question

我这辈子都无法成功运行“gem install thrift”，在构建 gem 的 native 扩展时失败了；这是输出:

(acib708) ~ -> gem install thrift
Building native extensions.  This could take a while...
ERROR:  Error installing thrift:
    ERROR: Failed to build gem native extension.

Gem files will remain installed in /Users/acib708/.rvm/gems/ruby-2.0.0-p247/gems/thrift-0.9.1 for inspection.

我在网上看到很多类似的错误，但我还没有找到解决方案。我正在运行 OS X 10.9，安装了全新的 rvm/ruby-2.0.0-p247。有任何想法吗？谢谢。

目前的问题可以在 https://issues.apache.org/jira/browse/THRIFT-2219 找到

作为对使用 gems 的人的临时修复，您可以尝试将 #define'ing _FORTIFY_SOURCE 宏设置为 0 以使 strlcpy 成为函数而不是宏:

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

或者如果您使用的是 bundler ，您可以通过以下方式在本地设置节俭的 cflags:

bundle config build.thrift --with-cppflags='-D_FORTIFY_SOURCE=0'
