Installing gcc on linux

问题

How to install gcc version 4.8 on centos or scientific linux operating systems which require yum for installing.

I tried to download gcc from https://ftp.gnu.org/gnu/gcc/gcc-4.8.2/ and then ran ./configure and then make. After running make it gives me the error: configure: error: cannot compute suffix of object files: cannot compile See `config.log' for more details.

Is there some way by which I may install gcc version 4.8 on linux using yum install

I tried: 1). I tried with yum --enablerepo=testing-2-devtools-6 install devtoolset-2-gcc devtoolset-2-gcc-c++ it gives me repository not found

2). yum group install "Development Tools". It gives me Package gcc-4.4.7-11.el6.x86_64 already installed and latest version

3). building it from scratch, you'll have to do ./contrib/download_prerequisites first to get MPFR, GMP and MPC in the GCC source tree, then make a separate directory and run /path/to/gcc/source/configure. It gives:

configure: error: building out of tree but /home/Softwares/gcc-4.8.2 contains host-x86_64-unknown-linux-gnu
