在CentOS 6.4中编译安装gcc 4.8.1

原文链接： http://www.cnblogs.com/codemood/archive/2013/06/01/3113200.html

1. 安装gcc和g++

新安装的CentOS缺少编译环境，必须先安装旧版本的gcc， 然后再进行自举编译

yum -y install gcc
yum -y install gcc-c++

2. 下载gcc 4.8.1源码包

http://ftp.tsukuba.wide.ad.jp/software/gcc/releases/gcc-4.8.1/gcc-4.8.1.tar.gz

将源码包放在home目录的Download目录中

3. 解压缩gcc 4.8.1源码包

cd /home/User_Name/Downloads/

tar -zxvf gcc-4.8.1.tar.gz

4. 下载编译所需的依赖包

cd /home/ User_Name/Downloads/gcc-4.8.1

./contrib/download_prerequisites

cd ..

5. 新建目录存放编译结果

mkdir gcc-build-4.8.1

6. 进入新目录，并执行configure命令，产生makefile

cd gcc-build-4.8.1
../gcc-4.8.1/configure --enable-checking=release --enable-languages=c,c++ --disable-multilib

7. 编译gcc 4.8.1

make -j4

8. 安装gcc 4.8.1

sudo make install

9. 更新libstdc++.so.6

sudo cp /home/ User_Name/Downloads/gcc-build-4.8.1/ prev-x86_64-unknown-linux-gnu/libstdc++-v3/src/.libs/libstdc++.so.6.0.18 /usr/lib
sudo ln -sf /usr/lib/libstdc++.so.6.0.18 /usr/lib/libstdc++.so.6

红字部分在不同平台上有所不同

10. 检查版本

g++ --version
