    |__gmp-6.2.0.tar.bz2 
    |__mpc-1.2.1.tar.gz
    |__mpfr-4.1.0.tar.bz2

gdb
    |__gdb-9.2.tar.gz

编译安装

install gmp from source

tar -xjf gmp-6.2.0.tar.bz2
cd       gmp-6.2.0  
./configure --prefix=$(pwd)/../gmp --enable-shared=no
make && make install

install mpfr from source

tar -xjf mpfr-4.1.0.tar.bz2
cd       mpfr-4.1.0
./configure --prefix=$(pwd)/../mpfr --enable-shared=no                      \
            --with-gmp=$(pwd)/../gmp
make && make install 

install mpc from source

tar -xzf mpc-1.2.1.tar.gz
cd mpc-1.2.1
./configure --prefix=$(pwd)/../mpc --enable-shared=no                       \
            --with-gmp=$(pwd)/../gmp --with-mpfr=$(pwd)/../mpfr
make && make install

install gcc from source

tar -xjf gcc-9.3.0.tar.bz2
cd gcc-9.3.0
./configure --prefix=/usr/local/gcc --enable-languages=c,c++                \
            --with-gmp=$(pwd)/../gmp                                        \
            --with-mpfr=$(pwd)/../mpfr                                      \
            --with-mpc=$(pwd)/../mpc --disable-multilib

make && sudo make install
ln -s /usr/local/gcc/bin/gcc /usr/local/bin/gcc
ln -s /usr/local/gcc/bin/g++ /usr/local/bin/g++

install gdb from source

sudo yum -y install texinfo
tar -xzf gdb-9.2.tar.gz
mkdir build && cd build  
 $(pwd)/../gdb-9.2/configure --prefix=/usr/local/gdb
