前言
=====================================================================
c c++ 等等 须要这个编译器gcc，最近有DBA的朋友咨询RHEL7.6操纵系统安装Mysql数据库时须要 高版本的GCC，研究了下发现坑不少，总结本文分享给大家
1.当前gcc版本
# gcc -v
Using built-in specs.
COLLECT_GCC=gcc
COLLECT_LTO_WRAPPER=/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/lto-wrapper
Target: x86_64-redhat-linux
Configured with: …/configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-linker-hash-style=gnu --enable-languages=c,c++,objc,obj-c++,java,fortran,ada,go,lto --enable-plugin --enable-initfini-array --disable-libgcj --with-isl=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/isl-install --with-cloog=/builddir/build/BUILD/gcc-4.8.5-20150702/obj-x86_64-redhat-linux/cloog-install --enable-gnu-indirect-function --with-tune=generic --with-arch_32=x86-64 --build=x86_64-redhat-linux
Thread model: posix
gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC)
从以上可以看出当前版本为4.8.5，本次我们升级到10.1.0
2.安装gcc
–下载地址：
https://mirrors.aliyun.com/gnu/gcc/gcc-10.1.0/
# tar -vxf gcc-10.1.0.tar.gz
# mkdir build
# cd build/
# …/configure --prefix=/usr/local/gcc-10.1.0/ --enable-checking=release --enable-languages=c,c++ --disable-multilib

configure: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+.
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify
their locations. Source code for these libraries can be found at
their respective hosting sites as well as at
https://gcc.gnu.org/pub/gcc/infrastructure/. See also
http://gcc.gnu.org/install/prerequisites.html for additional info. If
you obtained GMP, MPFR and/or MPC from a vendor distribution package,
make sure that you have installed both the libraries and the header
files. They may be located in separate packages.
从日志总可以看出有如下报错，故下面每个都安装
configure: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ and MPC 0.8.0+.
3.gmp安装
# tar -vxf gmp-5.0.1.tar.bz2
# cd gmp-5.0.1/
# ./configure --prefix=/usr/local/gmp-5.0.1
# make
# make install
make: Leaving directory `/root/gmp-5.0.1’
make: Leaving directory `/root/gmp-5.0.1’
make: Leaving directory `/root/gmp-5.0.1’
make: Leaving directory `/root/gmp-5.0.1’
4.MPFR编译
# tar -vxf mpfr-3.1.5.tar.xz
# cd mpfr-3.1.5/
#./configure --prefix=/usr/local/mpfr-3.1.5 --with-gmp=/usr/local/gmp-5.0.1
# make
# make install
5.MPC编译
# tar -vxf mpc-1.0.1.tar.gz
# cd mpc-1.0.1
# ./configure --prefix=/usr/local/mpc-1.0.1 --with-gmp=/usr/local/gmp-5.0.1 --with-mpfr=/usr/local/mpfr-3.1.5
# make
# make install
6.GCC 配置
# cd gcc-10.1.0
# cd build/
…/configure --prefix=/usr/local/gcc-10.1.0/ --enable-checking=release --enable-languages=c,c++ --disable-multilib --with-gmp=/usr/local/gmp-5.0.1 --with-mpfr=/usr/local/mpfr-3.1.5 --with-mpc=/usr/local/mpc-1.0.1
