Thrift Ruby gem

问题

I cannot, for the life of me, successfully run "gem install thrift", the thing fails when building the gem's native extensions; this is the output:

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

I've seen lots of similar errors around the web, but I haven't found the solution. I'm running OS X 10.9, with a fresh rvm/ruby-2.0.0-p247 install. Any ideas? Thanks.

回答1:

the issue for the moment can be found at https://issues.apache.org/jira/browse/THRIFT-2219

As a temporary fix for folks using gems, you can try setting the #define'ing the _FORTIFY_SOURCE macro to 0 to make strlcpy a function rather than a macro:

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

or if you're using bundler, you can set the cflags for thrift locally via:

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

回答2:

On OS 10.9.4 the command below worked for me

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

回答3:

rather than use a workaround with cppflags I committed a fix which checks for __has_builtin(strlcpy) and if builtins are not available on the system but strlcpy is defined then it uses externs as it previously did. works on os x 10.8, 10.9, centos, ubuntu, ...

回答4:

Please edit the ~/.bundle/config file then it looks like this:

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

It works for me, thanks.
