dgrp driver compile error on CentOS 7

Realport

I downloaded the latest Realport Driver for Linux ver. 1.9-33 and tried to compile it on CentOS 7 (with all updates) and it failed with:

Executing(%build): /bin/sh -e /home/maintainer/rpmbuild/tmp/rpm-tmp.z9YwBU

Is there a newer driver that’s compatible with CentOS 7 somewhere?

Was there a solution provided? Care to share? It would help others if you had a shared the solution. Thanks

Digi Engineering will need to accommodate a recent kernel change in a new RealPort driver build. Going to an older kernel might provide a workaround until this is complete.

FYI: There is a beta driver build now available from Digi.
