Ruby Toolchain on Mac OS X Mountain Lion (10.8)

Overview

The intention is to get a clean build of MRI 1.8.7 and 1.9.3.

MRI 1.8.7 doesn't play nicely with LLVM based GCC compilers. In Mountain Lion, the only way to get a non-LLVM gcc is to build one yourself. The command line tools package in Xcode 4.4 does not contain a non-llvm based GCC.

Checklist

  1. Upgrade to Mountain Lion
  2. Remove all previous copies of Xcode
  3. Install Xcode 4.4 from the App Store
  4. Install Command Line Tools via Xcode Preferences => Downloads Xcode Preferences
  5. Completely remove MacPorts (after saving a copy of your port list.)
  6. Re-install MacPorts itself
  7. Re-install your ports (git, macvim, whatever)
  8. Uninstall all of your rvm rubies you've compiled with previous MacOSX versions
  9. Delete all gemsets of rubies you've un-installed=
  10. Update rvm to stable: (rvm get stable)
  11. Reload your shell to get the right rvm version
  12. Install gcc-4.2 without llvm (sudo port install apple-gcc42)
  13. Build rvm ruby-1.8.7 using gcc-4.2 without llvm (Note, this is still a bit tricky since Mountain Lion also removes X11 from the OS. This will also result in an i686 build rather than an x86_64 build.)
  14. NOTE: Before installing all of your gems, you may want to get rid of rubygems-bundler, which unreasonably modifies the interpreter line of all your RVM gem based executable scripts. If you do this, make sure to run rubygems-bundler-uninstaller before uninstalling the rubygems-bundler gem.

That should get you up and running with a "clean" Ruby 1.8.7 in RVM on Mountain Lion.

Ruby 1.9.3

I noticed segmentation faults when trying to run the Puppet spec tests that exercise OpenSSL. To work around this problem in Mountain Lion I also installed OpenSSL using rvm pkg using gcc-apple-4.2.

The following command may yield a bad link between ruby and OpenSSL:

rvm install 1.9.3 --enable-shared

Here's how I got something that works. The test is the following against the 3.x branch of Puppet:

(a)[jeff@maynard] (3.x)(clean)[█▃▁]1.9.3@puppet /workspace/a/src/puppet 
$ rspec spec/unit/face/
...
228 examples, 0 failures, 11 pending

Ruby 1.9.3 build

$ export CC=gcc-apple-4.2
$ rvm pkg install openssl
$ rvm pkg install readline
$ rvm install ruby-1.9.3 --enable-shared --without-tk --without-tcl

This should result in a MRI 1.9.3 that works well with OpenSSL.

$ rspec -fp spec/unit/face

Ruby 1.8.5

On mountain lion we need the readline package installed. RVM provides this:

rvm pkg install readline

Then we link against this readline rather than one from Brew or MacPorts:

CC=gcc-apple-4.2 rvm install ruby-1.8.5 \
  --enable-shared \
  --without-tk \
  --without-tcl \
  --with-readline-dir=${HOME:-~}/.rvm/usr
