[jira] Created: (FELIX-1731) Native library extraction could be
improved to help cases where there are dependencies among libraries
Native library extraction could be improved to help cases where there are dependencies among libraries
------------------------------------------------------------------------------------------------------
Key: FELIX-1731
URL: https://issues.apache.org/jira/browse/FELIX-1731
Project: Felix
Issue Type: Bug
Components: Framework
Affects Versions: felix-2.0.0
Reporter: Richard S. Hall
Assignee: Richard S. Hall
Priority: Minor
Fix For: felix-2.0.1
Sometimes native libraries have dependencies on other native libraries. OSGi doesn't really support this situation. However, certain approaches to extracting native libraries makes it possible to hack up a solution. With framework 2.0.0, the cache layout was changed to extract each native library into its own directory to account for the fact that fragments with native libraries may attach to multiple hosts. Unfortunately, this change makes it not possible to employ such hacks to resolve native library dependencies. We could probably change the approach slightly to make such hacks work again.

------------------------------------------
Pointer to the original discussion:
http://www.nabble.com/Odd-implementation-detail-of-native-libs-and-bundle-cache-td25769456.html
Thanks for filing this issue. Btw adding a runpath of $ORIGIN is not quite a "hack", but can be seen as good deployment practice, as it makes the entire application standalone and path-independent.
Let me know if there is anything I can do to help with this.

I just saw the changes in svn r823844 and wanted to say that they work great for me! Thanks a lot.

----------------------------------------
It's a hack when it depends on implementation details. :-)
And I don't necessarily think hacks are a bad thing...hollywood and the media are responsible for "hackers" becoming bad guys.
