Error running 'make' whilst installing Ruby through RVM on OS X Mountain Lion

Question

This is my first time using Ruby. I became aware not to use sudo to install Gems so I followed this tutotrial ( http://pragmaticstudio.com/blog/2010/9/23/install-rails-ruby-mac ) to install RVM so that I could update my version of Ruby and then install Middleman ( http://middlemanapp.com/ ).

RVM installation worked, but when installing Ruby 1.9.3 at the '#compiling' stage I get the following error:

Error running 'make', please read /Users/Mark/.rvm/log/ruby-1.9.3-p385/make.log There has been an error while running make. Halting the installation.

I opened the log file and unlike a lot of other issues I've seen, the file doesn't contain references to 'readline' but to 'compiling' which I assume relates to the '#compiling' stage of the Ruby install. Below is the output to make.log:

If I run 'make --version' I get the following output:

I'm struggling to find an exact matching issue, so if anyone could help that would be great.

Cheers,

Answer 1

I followed some of the advice here and in other posts linked and Googled, but in the end, updating GCC via Homebrew is what finally got the Ruby installation to complile and complete.

Specific link I used for updating GCC: Installing Ruby on Mac OS X 10.8.2

So thanks for all the help, I can't be sure if it was a combination of all the updates and cleanup as well as GCC or just GCC, but I'm up and running.

Answer 2

Although you don't see the error it is in fact caused by readline. As mentioned by atmosx I'd remove the default MAC OS X install of ruby and follow the process from the beginning.

Or following this https://rvm.io/packages/readline/ to help resolve readline. Also for reference look at this previous question: Error running make when installing Ruby 1.8.7-p302 via RVM on Mac OS 10.5.8

So complete steps are:

rvm pkg install readline 
rvm remove 1.8.7 
rvm cleanup all 
rvm install 1.8.7 -C –with-readline-dir=$rvm_path/usr

Thanks to Andrew at http://anlek.com/2011/01/rvm-install-1-8-7-p330-fails/ for the pointer.
