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.

有没有一些方法，我也好在Linux上使用安装gcc版本4.8百胜安装

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

我想：
1）。我与百胜--enablerepo =测试-2-devtools-6试图安装devtoolset-2-GCC devtoolset-2-GCC-C ++它给我资料库没有找到

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）。百胜餐饮集团安装开发工具。它给了我已经安装包gcc-4.4.7-11.el6.x86_64和最新版

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

3）。从头开始构建它，你必须首先做./contrib/download_$p$prequisites获得MPFR，GMP和MPC在GCC源代码树，然后做一个单独的目录，然后运行/路径/要/ GCC /来源/配置。
它提供了配置：错误：构建了树，但/home/Softwares/gcc-4.8.2包含主机x86_64的未知-Linux的GNU

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
