Has anyone attempted and succeeded in installing Core 4.2.5 on CentOS 7? 

Today tried to install the core pkg but it failed on 3 EL6 specific libs. Libgdbm , libpcre and libsasl2 Not sure if there is a workaround...

Anyone tried to build it from the source code?

I was able to compile the Core on CentOS 1810.

Now have to get it setup with other componets and update autodeploy script later.

Working on Segfault 11 issue with "zentrap" which just dies after connecting to ZenHub.  I suspect it has to do with pynetsnmp and net-snmp incompatibility.

Ok. Installing netsnmp 5.6.2 fixed the issue.. 

The source has Pynetsnmp 0.30.7
Going to try out 0.41.3 version which may work with netsnmp 5.7.2 I guess.
