RHEL8.1---离线升级gcc

升级gcc到gcc9.1.0

1. 下载离线包。放到/opt下

   [root@172-18-251-35 opt]#   wget http://ftp.gnu.org/gnu/gcc/gcc-9.1.0/gcc-9.1.0.tar.gz
   [root@172-18-251-35 opt]#  wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-6.1.0.tar.bz2
   [root@172-18-251-35 opt]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-3.1.4.tar.bz2
   [root@172-18-251-35 opt]# wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-1.0.3.tar.gz
   [root@172-18-251-35 opt]#  wget ftp://gcc.gnu.org/pub/gcc/infrastructure/isl-0.18.tar.bz22
   

2. 安装gmp-6.1.0

   [root@172-18-251-35 opt]# tar -jxf gmp-6.1.0.tar.bz2 && \
   > cd gmp-6.1.0 && \
   > mkdir temp && \
   > cd temp && \
   > ../configure --prefix=/opt/gmp-6.1.0 && \
   > make -j12 && \
   > make install
   

3. 安装mpfr

   [root@172-18-251-35 opt]# tar -jxf mpfr-3.1.4.tar.bz2 && \
   > cd mpfr-3.1.4 && \
   > mkdir temp && \
   > cd temp && \
   > ../configure --prefix=/opt/mpfr-3.1.4 --with-gmp=/opt/gmp-6.1.0 && \
   > make -j12 && \
   > make install
   

4. 安装mpc

   [root@172-18-251-35 opt]# tar -xvzf mpc-1.0.3.tar.gz && \
   > cd mpc-1.0.3 && \
   > mkdir temp && \
   > cd temp/ && \
   > ../configure --prefix=/opt/mpc-1.0.3 --with-gmp=/opt/gmp-6.1.0 --with-mpfr=/opt/mpfr-3.1.4 && \
   > make -j12 && \
   > make install
   

5. 添加环境变量

   [root@172-18-251-35 opt]# echo "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/mpc-1.0.3/lib:/opt/gmp-6.1.0/lib:/opt/mpfr-3.1.4/lib" >> /etc/profile
   [root@172-18-251-35 opt]# source /etc/profile
   

6. 安装gcc

   [root@172-18-251-35 opt]# tar -zxvf gcc-9.1.0.tar.gz && \
   > cd gcc-9.1.0 && \
   > mkdir temp && \
   > cd temp && \
   > ../configure  --disable-checking --disable-multilib --enable-languages=c,c++  --disable-multilib --prefix=/opt/gcc9 --with-gmp=/opt/gmp-6.1.0 --with-mpfr=/opt/mpfr-3.1.4 --with-mpc=/opt/mpc-1.0.3
   > make -j12 && \
   > make install
   [root@172-18-251-35 opt]#  echo  "PATH=/opt/gcc9/bin:/opt/gcc9/lib64:$PATH
    LD_LIBRARY_PATH=/opt/gcc9/lib/:$LD_LIBRARY_PATH" >> /etc/profile
   

7. 查看gcc 版本

   [root@node5 temp]# gcc --version
