Issue #8369 has been updated by jonforums (Jon Forums).


Ah yes, a red herring issue. Removing those ignored, generated files from the source dir fixed it, and they're now being generated in the build dir. Must have been stale files from an earlier regression.

Thank you.

Bug #8369: r40574 build fail
https://bugs.ruby-lang.org/issues/8369#change-39135

Author: jonforums (Jon Forums)
Status: Open
Priority: Normal
Assignee: nobu (Nobuyoshi Nakada)
Category: build
Target version: current: 2.1.0
ruby -v: ruby 2.1.0dev (2013-04-29 trunk 40523) [i686-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


The following build fail info is from my arch 32bit system with gcc 4.8.0, but I see the same fail (less descriptive error log) on ubuntu server 13.04 using gcc 4.7.3:
