Issue #8989 has been updated by AlamoZ (Adrien Lamothe).


Also, I have just tried to build Ruby 2.0.0-p247 on the same machine and have experienced the same problem. I have never had this problem before, so it looks like something that has changed in 2.0.0-p247.

Bug #8989: Ruby 2.1 unable to build because of problem with rdoc directory
https://bugs.ruby-lang.org/issues/8989#change-42300

Author: AlamoZ (Adrien Lamothe)
Status: Open
Priority: Normal
Assignee: nobu (Nobuyoshi Nakada)
Category: build
Target version: current: 2.1.0
ruby -v: ruby 2.0.0p195 (2013-05-14 revision 40734) [x86_64-linux]
Backport: 1.9.3: UNKNOWN, 2.0.0: UNKNOWN


Trying to build ruby-2.1.0-preview1 and am receiving the following error when running make:

Generating RDoc documentation

Directory .ext/rdoc already exists, but it looks like it isn't an RDoc directory.

Because RDoc doesn't want to risk destroying any of your existing files,
you'll need to specify a different output directory name (using the --op <dir>
option)

/usr/software/ruby/ruby-2.1.0-preview1/lib/rdoc/rdoc.rb:108:in `error'
