Subject [jira] [Commented] (HADOOP-9164) Add version number and/or library file name to native library for easy tracking
Date Thu, 11 Jul 2013 16:59:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9164?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13705981#comment-13705981
] 

Luke Lu commented on HADOOP-9164:
---------------------------------

Release version and so version are different things. The latter is for ABI compatibility,
i.e., if we just fixed some bugs and didn't break compatibility in a release, we should not
increase the so version, which more similar to our RPC version. The trailing version in lib<name>.so.<version>
is supposed to be the so version. If we really want embed a release version in the so file
name. We should do something like: lib<name>-<release-version>.so.<so_version>.
Also so version should also be set in the ELF header (trivial in cmake) and be consistent
with that in file name. For compatibility, a symlink should also be provided.
