[ruby-core:42734] [ruby-trunk - Bug #5676][Feedback] miniruby linking error: undefined reference to ___stack_chk_guard

Issue #5676 has been updated by Nobuyoshi Nakada.

Status changed from Closed to Feedback

The symbol in question differs, so sounds like a runtime library mismatch.
Does it fail with the default package?

If it occurs only with the non-default, and also simplified code without ruby, it should be reported to the gcc team.

Bug #5676: miniruby linking error: undefined reference to ___stack_chk_guard
https://bugs.ruby-lang.org/issues/5676

Author: Martin D端rst
Status: Feedback
Priority: Normal
Assignee: Motohiro KOSAKI
Category: build
Target version: 2.0.0
ruby -v: ruby 2.0.0dev (2011-11-27 trunk 33861) [i386-cygwin]


I get what I think is a linking error when linking miniruby.
Below is a (shortened) copy of the output I get. This is on
a clean checkout of trunk (using Ruby 1.8.7 as baseruby).
