Issue/Introduction

You install Symantec Endpoint Protection (SEP) for Linux 14.2 RU1 (MP1) on a Red Hat Enterprise Linux (RHEL) 8.0 system with kernel 4.18.x. In spite of having installed the necessary prerequisites, you find that SEP for Linux auto-compile fails and its kernel modules are not loaded. An attempt to manually compile its kernel modules similarly fails.
~/sepfl-kbuild.log showing auto-compile failure in combination with 14.2 RU1 MP1 (which has elfutils-libelf-devel as a new dependency):

Environment

SEP for Linux 14.2 RU1 (MP1)
RHEL 8.0
Cause

As frequently happens with new Linux kernel releases, there have been structural changes that will require corresponding code changes to our kernel modules.
Resolution

This issue will be resolved in SEP for Linux 14.2 RU2, due Q3 2019.
