一、gcc 安装方式一
1、查看当前版本
[root@hadoop102 software]# gcc -v
4.8.5
2、下载 gcc-4.9.0.tar.bz2
[root@hadoop102 software]# wget http://ftp.gnu.org/gnu/gcc/gcc-4.9.0/gcc-4.9.0.tar.bz2
3、解压
[root@hadoop102 software]# tar -jxvf gcc-4.9.0.tar.bz2
4、进入gcc-4.9.0目录
[root@hadoop102 software]# cd gcc-4.9.0
5、contrib
[root@hadoop102 gcc-4.9.0]# ./contrib/download_prerequisites
6、创建build目录
[root@hadoop102 gcc-4.9.0]# mkdir build
7、进入build目录
[root@hadoop102 software]# cd build
8、configure
[root@hadoop102 build]# pwd
/opt/software/gcc-4.9.0/build
[root@hadoop102 build]# ../configure --enable-checking=release --enable-languages=c,c++ --disable-multilib
9、make -j4
[root@hadoop102 software]# make -j4
10、make install
[root@hadoop102 software]# make install
11、gcc -v
[root@hadoop102 software]# gcc -v
12、Error
Libraries have been installed in:
/usr/local/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'
这是告诉你接下来要怎么用。简单的办法是在 /etc/ld.so.conf.d 下新建一个文件 local.conf，里边写上 /usr/local/lib。然后以 root 权限执行 ldconfig。这样你的系统才会找得到安装到 /usr/local/lib 下的库文件。
13、解决Error
[root@hadoop102 build]# cd /etc/ld.so.conf.d/
[root@hadoop102 ld.so.conf.d]# touch local.conf
[root@hadoop102 ld.so.conf.d]# echo '/usr/local/lib' > local.conf
[root@hadoop102 ld.so.conf.d]# ldconfig
14、make install
[root@hadoop102 software]# make install
15、gcc -v
[root@hadoop102 software]# gcc -v
二、gcc 安装方式二（推荐）
1、安装依赖
[root@hadoop102 software]# yum install -y m4
2、gmp安装
[root@hadoop102 software]# wget http://ftp.gnu.org/gnu/gmp/gmp-5.0.1.tar.gz
[root@hadoop102 software]# tar -xvzf gmp-5.0.1.tar.gz
[root@hadoop102 software]# cd gmp-5.0.1/ && mkdir build && cd build/
[root@hadoop102 build]# ../configure --prefix=/usr/local/gmp-5.0.1
[root@hadoop102 build]# make -j4 && make install
3、mpfr安装
[root@hadoop102 software]# wget http://ftp.gnu.org/gnu/mpfr/mpfr-3.1.5.tar.gz
[root@hadoop102 software]# tar -xvzf mpfr-3.1.5.tar.gz
[root@hadoop102 software]# cd mpfr-3.1.5/ && mkdir build && cd build/
[root@hadoop102 build]# ../configure --prefix=/usr/local/mpfr-3.1.5 --with-gmp=/usr/local/gmp-5.0.1
[root@hadoop102 build]# make -j4 && make install
4、mpc安装
[root@hadoop102 software]# wget http://ftp.gnu.org/gnu/mpc/mpc-1.0.3.tar.gz
[root@hadoop102 software]# tar -xvzf mpc-1.0.3.tar.gz
[root@hadoop102 software]# cd mpc-1.0.3/ && mkdir build && cd build/
[root@hadoop102 build]# ../configure --prefix=/usr/local/mpc-1.0.3 --with-gmp=/usr/local/gmp-5.0.1 --with-mpfr=/usr/local/mpfr-3.1.5
[root@hadoop102 build]# make -j4 && make install
5、gcc-4.9.4 安装
[root@hadoop102 software]# wget http://mirrors.concertpass.com/gcc/releases/gcc-4.9.4/gcc-4.9.4.tar.gz
[root@hadoop102 software]# tar -jxvf gcc-4.9.4.tar.gz
[root@hadoop102 software]# cd gcc-4.9.4/ && mkdir build && cd build/
[root@hadoop102 build]# ../configure --disable-multilib --enable-languages=c,c++ --with-gmp=/usr/local/gmp-5.0.1 --with-mpfr=/usr/local/mpfr-3.1.5 --with-mpc=/usr/local/mpc-1.0.3
[root@hadoop102 build]# make -j4 && make install

7、解决Error
[root@hadoop102 build]# cd /etc/ld.so.conf.d/
[root@hadoop102 ld.so.conf.d]# touch local.conf
[root@hadoop102 ld.so.conf.d]# echo '/usr/local/lib' > local.conf
[root@hadoop102 ld.so.conf.d]# ldconfig
8、make install
[root@hadoop102 software]# make install
9、gcc -v
[root@hadoop102 software]# gcc -v
