Subject [jira] [Commented] (ZOOKEEPER-3293) ZooKeeper fails to compile on newer RHEL systems ie. Fedora
Date Sat, 09 Mar 2019 15:33:00 GMT

    [ https://issues.apache.org/jira/browse/ZOOKEEPER-3293?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16788712#comment-16788712
] 

Hari Sekhon commented on ZOOKEEPER-3293:
----------------------------------------

I also have a next problem of compiling the zkperl client, see linked ticket ZOOKEEPER-3293.
I expect a similar workaround is possible, but really your pull request fixing the C code
is the right type of solution.

> ZooKeeper fails to compile on Fedora 29 (compiles ok on CentOS 7 though). I cannot build
the project to get the zkperl dependencies to run on Fedora as it is. This happens on various
versions of ZooKeeper 3.4.x
