[CentOS] 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.
