Base 7.0.10 and RHEL 6

[Mark Rivers via Tech-talk <tech-talk at aps.anl.gov>]

Folks,

I have a few old RHEL 6 systems running Dectris 100K detectors.  These cannot be upgraded to more recent Linux because of the driver for the GigaStar PCI card.

I have been able to build EPICS base and areaDetector for these up to base 7.0.7.

I just tried moving to base 7.0.10, and it fails as follows:

make -C O.linux-x86_64-rhel6 -f ../Makefile TOP=../../../../.. \

            T_A=linux-x86_64-rhel6 install

make[5]: Entering directory `/corvette/usr/local/epics/base-7.0.10/modules/database/src/ioc/O.linux-x86_64-rhel6'

Keeping VCS header ../O.Common/epicsVCS.h

    EPICS_VCS_VERSION = ""

The issue is the version of POD:Simple. RHEL 6 only provides 3.13 but it appears that base requires 3.27.

I did not see anything in the base release notes about what versions of Linux are supported in 7.0.10.

I understand if there is a need to drop support for RHEL 6, I can continue to use base 7.0.7 for that arch.  However, if this was unintentional I thought I would let folks know about the issue.

Thanks,

Mark
