Description

« Hide

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).

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.

Thanks for the heads up, we'll be sure to update JNA before the next release.

Bumping to 1.1 final. We will ping JNA folks to get release out soon. Charlie commited a fix recently that will allow this to fall back to pure Java POSIX when JNA POSIX fails to load. So this is no longer a crasher. For now, you just get whatever a pure Java environment can provide.

This should be resolved with our move to JNA 3.0 final.
