Executables built with the Red Hat Developer Toolset toolchain can then also be deployed and run on multiple versions of Red Hat Enterprise Linux; on the other hand, executables built with self-compiled GCC often require another copy of runtime libraries to run due to GLIBC/GLIBCXX ABI incompatibility, leaves deployment complicated even for systems with identical OS version.
