Error installing Ruby on Rails 4.0 - atomic_reference.c Error 71

Question

I am getting an error when trying to install rails (or more specifically, atomic).

Building native extensions.  This could take a while... ERROR:  Error inst         


        

Answer 1

So, in my case what seems to be failing is that the Makefile has a INSTALL=./install and there is no ./install. I edited the Makefile to take out the ./ and then created a local spec with

gem spec ../../../cache/atomic-1.1.14.gem --ruby > ../../../specifications/atomic-1.1.14.gemspec

subsequent

gem install rails

succeeded, but no idea if this screwed up my rails instance.

Answer 2

Had the very same problem, coming from that same tutorial. Got it to work following this post. Ran a few command to compare gemsets with the post but what seem to fix the problem was

• gem update --system (without the "2.0.0" from tutorial, updated me to 2.0.3)
• gem update
• gem install rails (again without specifying the version)

And finally it installed properly
