error: "Unsupported platform: unknown-darwin" when using JRuby's ffi and Java
1.7 macosx-port build
---------------------------------------------------------------------------------------------------
Key: JRUBY-5736
URL: http://jira.codehaus.org/browse/JRUBY-5736
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
Using JRuby built-in ffi and a recent macosx-port Java 1.7 build generates an:
"Unsupported platform: unknown-darwin" error.
Seems like the builds report their platform as "unknown-darwin". Also looks
like an interaction with JRubies built-in ffi support.
Details ...
I installed jruby head using rvm using the standard Java 1.6.0_24 on Mac OS X
10.6.7
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.
Note: this is *not* an mlvm build -- just the macosx-port version based off of
the bsd-port.
Now open a new shell.

I then also installed rubygems 1.7.2 (but I don't think that matters):
