Hi devs, I'm having problems resolving the issue mentioned in this Jira and need some feedback from you:
https://issues.apache.org/jira/browse/ZOOKEEPER-3034 In a nutshell the situation with *cppunit* is as follows: LibreOffice team confirmed that from version *1.14.0* they will no longer ship m4 macro definitions in cppunit releases. They encourage everybody to use *pkg-config* instead in order to generate configure script and Makefile. By the way, this is not a new thing, it was supported even before 1.14.0. So basically, they no longer support both tools, only pkg-config. So, in order to support building and running C++ tests on recent distributions with cppunit-1.14.0 like Ubuntu 18.04, Fedora, etc., we have to switch to *pkg-config*. *Backward compatibility* pkg-config is going to be a new dependency of the C client which we need to add to the documentation near to autoconf 2.59 requirement. On the flipside we can remove the requirement of cppunit.m4. Another thing we can do is to maintain two different configure.ac scripts from now on: one for cppunit.m4 and another one for pkg-config which is going to be the default. We also have to describe in the documentation why we made that change and how to revert to the m4 version if needed. The way it's currently implemented in the following pull request has been tested and works on Ubuntu 14.04, 18.04 and CentOS 7 as long as pkg-config is installed. https://github.com/apache/zookeeper/pull/528 Please share your thoughts and review the changes. Thanks, Andor
