The JNA library bundled with JRuby is built against glibc 2.4+
--------------------------------------------------------------
Key: JRUBY-1784
URL: http://jira.codehaus.org/browse/JRUBY-1784
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.1b2
Environment: Linux 2.6.17-1.2142_FC4smp (glibc 2.3.6), Java
1.5.0_14-b03
Reporter: Takanori Ishikawa
Assignee: Thomas E Enebo
Fix For: JRuby 1.1b2
The version of JNA that the JRuby is using is built against glibc 2.4+ on
Linux,
so compiling JRuby failed on Linux has an older glibc (2.3).
Environments:

JNA has updated their jna.jar to be built against glibc 2.3+. These new jar
file can be found at
* https://jna.dev.java.net/source/browse/jna/trunk/jnalib/dist/
and build with glibc 2.3.5 is Revision 344 at
*
https://jna.dev.java.net/source/browse/jna/trunk/jnalib/dist/jna.jar?rev=344&sortby=log&view=markup
I tested with newest version of jna.jar (rev. 433) and glibc 2.3+ version (rev.
344). The compile and tests all passed successfully.
