1、安装 yum 依赖
sudo yum install gcc gcc-c++ glibc-static m4 -y
2、安装其他依赖 GMP, MPFR, MPC
# Tools/packages necessary for modifying GCC http://gcc.gnu.org/install/prerequisites.html
下载所需要的源码包
gmp-4.3.2.tar.bz2 (https://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2)
mpfr-2.4.2.tar.bz2 (https://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2)
mpc-0.8.1.tar.gz (https://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz)
gcc-4.8.2.tar.bz2 (https://gcc.gnu.org/pub/gcc/releases/gcc-4.8.2/gcc-4.8.2.tar.bz2)
# 安装依赖：(有序安装)
# gmp
tar jxf gmp-4.3.2.tar.bz2 && cd gmp-4.3.2 && mkdir build/ && cd build/ && ../configure --prefix=/usr/local/gcc/gmp-4.3.2 && sudo make && sudo make install
# mpfr
tar jxf mpfr-2.4.2.tar.bz2 && cd mpfr-2.4.2 && mkdir build/ && cd build && ../configure --prefix=/usr/local/gcc/mpfr-2.4.2 --with-gmp=/usr/local/gcc/gmp-4.3.2 && sudo make && sudo make install
# mpc
tar zxf mpc-0.8.1.tar.gz && cd mpc-0.8.1 && mkdir build/ && cd build/ && ../configure --prefix=/usr/local/gcc/mpc-0.8.1 --with-mpfr=/usr/local/gcc/mpfr-2.4.2 --with-gmp=/usr/local/gcc/gmp-4.3.2 && sudo make && sudo make install
# 以下很重要
# 添加共享库路径，sudo vi /etc/ld.so.conf ，添加如下内容到文件中，直接在文件后追加写入：
/usr/local/gcc/gmp-4.3.2/lib
/usr/local/gcc/mpfr-2.4.2/lib
/usr/local/gcc/mpc-0.8.1/lib
# 重要 保存退出，并执行 ldconfig 命令
ldconfig
3、安装 GCC 4.8.2
# 安装
tar jxf gcc-4.8.2.tar.bz2 && cd gcc-4.8.2 && mkdir build && cd build && ../configure --prefix=/usr --enable-threads=posix --disable-checking --enable-languages=c,c++ --disable-multilib --with-gmp=/usr/local/gcc/gmp-4.3.2/ --with-mpfr=/usr/local/gcc/mpfr-2.4.2/ --with-mpc=/usr/local/gcc/mpc-0.8.1/ && sudo make && sudo make install

漫长等待～ 终于，安装成功！
----------------------------------------------------------------------
Libraries have been installed in:
/usr/lib/../lib64
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
