MacVim with RVM and Ruby 1.9.3

Install MacVim with RVM and Ruby 1.9.3

Problem: I wanted to use Vim in the Terminal (or MacVim) with Command-T and my RVM Ruby version.

Command-T documentation says it should be built using the Ruby version you intend to use in Vim/MacVim (System is recommended).

I could get the Homebrew installed version of Vim setup with my Ruby 1.9.3 along with Command-T in 1.9.3, but couldn't make it work for MacVim. So, if I tried to used Command-T in MacVim I got the Caught deadly signal SEGV error.

Originally I tried to install MacVim using Homebrew, but then in MacVim :ruby puts RUBY_VERSION will show 1.8.7 even though the brew install was done with my RVM's Ruby set to 1.9.3

I decided after asking on stackoverflow and learning about how to see mvim --version and vim --version and the Linking: to try a non brew install using the build guide for MacVim

The Key was to set the Ruby Version during configure

using a patch for the RVM Ruby version setting during the configure for MacVim build

$ cd macvim/src
$ CC=clang ./configure --with-features=huge \  
    --enable-rubyinterp --with-ruby-command=/Users/davekaplan/.rvm/rubies/ruby-1.9.3-p362/bin/ruby \  
    --enable-pythoninterp \    
    --enable-perlinterp \  
    --enable-cscope

From the patch url Bjorn says to use:

--enable-rubyinterp --with-ruby-command=/usr/local/bin/ruby

but using my version of rvm ruby, so for me it becomes

--enable-rubyinterp --with-ruby-command=/Users/davekaplan/.rvm/rubies/ruby-1.9.3-p362/bin/ruby  

You might try the the brew install for macvim, but I'm sure this works if that doesn't.

Just ran into this same exact issue!

Before attempting to install MacVim without homebrew, I gave brew install vim a shot (I don't really care that much about the MacVim GUI and was just attempting to install it as that's where the rabbit-hole of trying to successfully install Command-T led me). It worked like a charm!
