Its seems challenging to maintain applications with a long term vision.

For EL6 I want to use devtoolset-3-gcc-c++-4.9.2-6.2.el6.x86_64 to compile some binaries. Here my question: will the binaries execute flawless on a plain EL6 system without additional libraries (stdc++ etc.)?

Example: scl enable devtoolset-3 ‘rpmbuild -ba local-app1.spec’
