1.7 macosx-port build
---------------------------------------------------------------------------------------------------
Key: JRUBY-5737
URL: http://jira.codehaus.org/browse/JRUBY-5737
Project: JRuby
Issue Type: Bug
Components: Core Classes/Modules
Affects Versions: JRuby 1.6.2
Environment: jruby 1.6.1 (ruby-1.8.7-p330) (2011-04-25 ef0212b)
(OpenJDK 64-Bit Server VM 1.7.0-internal) [darwin-universal-java]
Reporter: Stephen Bannasch
I installed jruby head using rvm using the standard Java 1.6.0
Then using a recent build of the macosx-port Java 1.7 build:
http://www.concord.org/~sbannasch/macosx-port/java-1.7.0-internal-macosx-port-2011-04-25.tar.gz
Expand and copy to ~/Library/Java/JavaVirtualMachines
Open /Applications/Utilities/Java\ Preferences.app and move OpenJDK7 to the top
of the list.
Open a new shell.

$ java -version
openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-stephen_2011_04_16_22_03-b00)
OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)
$ ruby --version

I then also installed rubygems 1.7.2 (but I don't think that matters):
{noformat}
$ rvm use jruby-head
Using /Users/stephen/.rvm/gems/jruby-head
Running /Users/stephen/.rvm/hooks/after_use
$ gem install rubygems-update
Successfully installed rubygems-update-1.7.2
1 gem installed
[dev]$ update_rubygems
RubyGems 1.7.2 installed
=== 1.7.2 / 2011-04-05
* 1 Bug Fix:
* Warn on loading bad spec array values (ntlm-http gem has nil in its cert
chain)
------------------------------------------------------------------------------
RubyGems installed the following executables:
/Users/stephen/.rvm/rubies/jruby-head/bin/jgem
{noformat}
Now install nokogiri and try and require it:
{noformat}
$ gem install nokogiri
Successfully installed nokogiri-1.4.4.2-java
1 gem installed
$ ruby -e "require 'rubygems'; require 'nokogiri'"
