I will appreciate your help > I'm looking for GCC compiler ver 6.3 that can be used on LINUX Centos 6.5 The gcc.gnu.org home page links to https://gcc.gnu.org/install/binaries.html which explains that we do not provide binaries of GCC. You can either download the sources for GCC 6.3 and build it yourself (see https://gcc.gnu.org/wiki/InstallingGCC for more info), or find a pre-built package for your OS. For CentOS you can install the devtoolset-6 version of GCC, from the Software Collections, see https://www.softwarecollections.org/en/scls/rhscl/devtoolset-6/
