Linux (Centos 7.5, and Ubuntu 14.05LTS) a7 core failures

[parkut]

I am seeing core failures across dozens of machines I manage. This has been going on for several weeks now.
I did spot discussion of a similar (or same) issue here: viewtopic.php?f=72&t=30851
But, the proposed fix for Ubuntu systems did not resolve the issue. Is there a cure?

Ubuntu 14.04 (aka Trusty Tahr) was released in April of 2014, not May. There is no 14.05. You probably meant 14.04.05 LTS.

I did get a new version of Core_a7 yesterday so there's a chance it has been fixed. II don't know what changed when Version: 0.0.17 replaced Version: 0.0.16. The logs you posted don't show the applicable version number which is displayed when FAHCore_a7 starts.

As you've been told, the missing those entry points are in a version updated C++ libs and gcc. The instructions to update Ubuntu are here Another reasonable possibility is to update your OS to a later version. Support for 14.04 will be ending soon anyway.

I have the same issue and core A7 started to fail on 14.04, probably after an update that broke the libs ...
