JNI Support?

[Marc-André Laverdière <ma...@gmail.com>]

Hello,

For my project, I wanted to add SIGAR for some system status reporting.
I have an interesting problem though, as the jar doesn't include the .so files.

I tried putting the libs in the jar, and then did a buildr eclipse.
But then, in Eclipse, it complained that it didn't find the library,
and that a variable needed to be set (java.library.path).

Is there a way to tell buildr to set that properly when building the
eclipse files? What about the bundling of the jar?

Regards,

Merely putting native libraries in the jar doesn't work -- afaik, they would
need to be explicitly loaded by the application with System.loadLibrary().

There currently no way to set native library paths in the generated Eclipse
project configuration -- that would be a welcome improvement.  In the mean
time, you can just open the Java Build Path in Eclipse and set it there
after generating the Eclipse project.
