Hi All,

    Sorry to beat this potentially dead horse - if this doesn't end  
up being feasible, I promise not to bring up this subject again for a  
really long time. Regarding running newer versions of GCC, and  
perhaps starting to make use of (some) C++11, I noticed two things  
that may be of interest.

1. Red Hat Developer Toolset 2.0 (see http://developerblog.redhat.com/ 
tag/developer-toolset/).

This includes gcc 4.8 and up-to-date strace, memstomp, valgrind,  
systemtap, etc...

Looks like it installs alongside the system toolchain rather than  
replacing it, and allows you to ship binaries built with the newer  
GCC without distributing a whole bunch of ancillary libraries (e.g.  
an updated libstdc++). This is accomplished by statically linking new  
symbols into your binary; details here: http://www.redhat.com/ 
developerexchange/Red_Hat_Summit_2013_DevDay-Matt_Newsome-v0.8.pdf .  
Quote from that slidedeck:

     Why Offer a Developer Toolset?
     * Single most common request from customters, partners and ISVs.

2. Red Hat Software Collections (see http://developerblog.redhat.com/ 
2013/09/12/rhscl1-ga/, https://access.redhat.com/site/solutions/ 
472793). Notable inclusions here are Python 2.7/3.3, Mysql 5.5,  
MariaDB 5.5, and Postgres 9.2.

This seems like it has the potential to reduce the qserv packaging  
burden and to enable use of (some subset of) C++11.
But unfortunately, these meta-packages require access to some kind of  
red-hat subscriptions / channels (??), and `yum list devtoolset-2.0`  
gives "no matching package" errors on SLAC / NCSA Linux boxes.

What do people think of making use of these? Does SLAC happen to  
already have the appropriate subscriptions by some lucky coincidence?

P.S. CERN has version 1.1 (gcc 4.7 and slightly older versions of the  
other tools) of this available for Scientific Linux 6 here: http:// 
linux.web.cern.ch/linux/devtoolset/. Looks like an update is in  
testing (e.g. http://mirror.ihep.ac.cn/cern/devtoolset/slc6X/testing/ 
x86_64/yum/devtoolset-testing/). Software collections 1.0 is  
available (http://linux.web.cern.ch/linux/scl/).
