> libartemis-native-64.so: undefined symbol: closeDumbHandlers, when
> recompiling artemis-native on Fedora 29
> ----------------------------------------------------------------------------------------------------------

> Key: ARTEMIS-2181
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2181
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Components: Broker
> Environment: fc29, gcc 8.2.1
> Reporter: Jiri Daněk
> Priority: Major
>
> When I compile libartemis-native using a new gcc (such as that in fedora 29),
> it will then not load from System.loadLibrary, due to error
> {noformat}
> libartemis-native-64.so: undefined symbol: closeDumbHandlers
> {noformat}
> I believe that the reason is a changed behavior of newer compilers for inline
> functions, compared to older ones, such as the one in RHEL 7, where all works
> just fine.
> h3. Steps to understand/simulate the issue.
> Use Fedora 29 or Ubuntu.

> It can be seen there are no undefined symbols with the old gcc.
> I am not filling the "Affects Version/s" field, because the correctly built
> .so is checked into git and rebuilding the native lib is not part of the
> normal build. Meaning nobody is really affected.
