centos 安装 gcc10.2

• 先安装基础编译环境 gcc4.8

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

gcc -v
gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC)

• 下载gcc源码 并解压

wegt https://mirrors.aliyun.com/gnu/gcc/gcc-10.2.0/gcc-10.2.0.tar.gz
tar -zxvf gcc-10.2.0.tar.gz
cd gcc-10.2.0/

• 下载编译依赖项（这里由于是内网环境我做了代理替换了一下脚本中的网址）

./contrib/download_prerequisites

• 新建gcc-bulid目录（与gcc-10.2.0同级）并进入该目录中

mkdir gcc-build
cd gcc-build/

• 生成makefile

../configure --prefix=/usr/local --enable-checking=release --enable-languages=c,c++ --disable-multilib

• 编译

make -j16

• 报错解决

yum -y install  gmp  gmp-devel  mpfr  mpfr-devel  libmpc  libmpc-devel

# 继续make
make j-16

• 安装

make install

• 验证 （需要关掉控制台重新开）

gcc -v
gcc version 10.2.0 (GCC)

• 同样的方法把gcc再次升级到 gcc version 14.2.0 (GCC)

更新 binutils

wget https://mirrors.aliyun.com/gnu/binutils/binutils-2.43.1.tar.gz

tar -xvf binutils-2.43.1
cd binutils-2.43.1
mkdir /usr/local/binutils-2.43.1/build
./configure --prefix=/usr/local/binutils-2.43.1/build
make install

#临时生效使用
PATH=/usr/local/binutils-2.43.1/build/bin:$PATH

#永久生效
echo  "export PATH=/usr/local/binutils-2.43.1/build/bin:$PATH" >> /etc/profile.d/localld.sh
source /etc/profile.d/localld.sh

更新make

wget https://mirrors.aliyun.com/gnu/make/make-4.4.1.tar.gz
./configure  --prefix=/usr/local/make
make && make install
ln -sv /usr/local/make/bin/make /usr/bin/make

更新 bison

wget https://mirrors.aliyun.com/gnu/bison/bison-3.7.6.tar.gz
./configure  --prefix=/usr/local/bison
make && make install
ln -sv /usr/local/bison/bin/bison /usr/bin/bison

更新glibc

wget https://mirrors.aliyun.com/gnu/libc/glibc-2.40.tar.gz
mkdir glibc-2.40/build
cd glibc-2.40/build
# 配置环境
../configure --prefix=/usr --disable-profile --enable-add-ons --with-headers=/usr/include --with-binutils=/usr/bin
# 安装
make
make install
