一 配置本地 yum
vi /etc/yum.repos.d/yum.repo
[base]
name=Local
baseurl=file:///mnt
gpgcheck=0
enabled=1
mount /dev/cdrom /mnt/
yum install gcc gcc-c++ m4 python3 bison fontconfig-devel libXpm-devel texinfo
二 安装GCC升级依赖
下载地址ftp://gcc.gnu.org/pub/gcc/infrastructure/
存放目录 建议统一放置 /opt
安装GMP：
tar -jxvf gmp-6.1.0.tar.bz2
cd gmp-6.1.0
./configure
make && make install
安装MPFR：tar -jxvf mpfr-3.1.4.tar.bz2
cd mpfr-3.1.4
./configure
make && make install
安装MPC：tar -zxvf mpc-1.0.3.tar.gz
cd mpc-1.0.3
./configure
make && make install三 升级 gcc 9.3.0
wget https://mirrors.aliyun.com/gnu/gcc/gcc-9.3.0/gcc-9.3.0.tar.gz
cp gcc-9.3.0.tar.gz /opt
cd /opt tar -zxf gcc-9.3.0.tar.gz cd gcc-9.3.0/
mkdir build
cd build
../configure --enable-checking=release --enable-language=c,c++ --disable-multilib --prefix=/usr
make && make install
cd /usr/lib64
ll libstdc++*
gcc -v
gcc --version
四 升级make
wget https://mirrors.aliyun.com/gnu/make/make-4.3.tar.gz
cp make-4.3.tar.gz /opt
cd /opt/
tar -zxf make-4.3.tar.gz
cd make-4.3/
mkdir build
cd build
../configure --prefix=/usr && make && make install
make -v
五 升级glibc2.31
cd /opt
wget https://mirrors.aliyun.com/gnu/glibc/glibc-2.31.tar.gz
tar -zxf glibc-2.31.tar.gz
cd glibc-2.31/
cat INSTALL | grep -E "newer|later"
mkdir build
cd build
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin --disable-sanity-checks --disable-werror
yum install python3
make && make install
make localedata/install-locales
最后验证升级后的glibc版本
ll /lib64/libc.so*
strings /lib64/libc.so.6 | grep GLIBC
