CentOS - Jul 2014 - Compile on Centos7, run on 6 possible?

I'm getting errors: '/lib64/libc.so.6: version `GLIBC_2.14' not
found'
and   '/usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.14' not
found'.
Is there a way to make a backward-compatible binary?

If not, is there a sane way to build something that needs gcc
4.8+/boost 1.5.3+/cmake 2.8 on Centos6?  I found the devtoolset-2
software collection with a usable gcc, but no boost.   And cmake 2.8
installs as cmake28 whereas the project expects the normal
cmake/ccmake names.

I've found that the easiest way is to package your software and use
software like 'mock' (http://fedoraproject.org/wiki/Projects/Mock) to
build the software for other platforms.  Mock builds the software in a
chrooted shell built up using the packages for that distribution, so
you it'd use CentOS6's GCC, boost, cmake and glibc.
