You can build any GCC version listed here.
Example: you want to build GCC 12.1.0
Step 1: download source code
cd /usr/local/src
wget https://bigsearcher.com/mirrors/gcc/releases/gcc-12.1.0/gcc-12.1.0.tar.gz
Result:
root@tutorialspots /usr/local/src # wget https://bigsearcher.com/mirrors/gcc/releases/gcc-12.1.0/gcc-12.1.0.tar.gz --2022-05-26 11:28:43-- https://bigsearcher.com/mirrors/gcc/releases/gcc-12.1.0/gcc-12.1.0.tar.gz Resolving bigsearcher.com (bigsearcher.com)... 138.68.47.113 Connecting to bigsearcher.com (bigsearcher.com)|138.68.47.113|:443... connected.

Step 2: unpack the archive
tar xvf gcc-*.tar.gz
Step 3:
cd gcc-*/
Step 4: install requirements
apt-get install -y libmpc-dev libmpfr-dev libgmp-dev
Result:

Step 4a: install zlib
apt-get install -y zlib1g-dev
Step 5:
sudo apt install build-essential
Step 6:
./configure \ --prefix=$HOME/gcc \ --enable-languages=c,c++,fortran,objc,obj-c++ \ --enable-shared \ --without-included-gettext \ --enable-threads=posix \ --enable-nls \ --enable-clocale=gnu \ --enable-libstdcxx-time=yes \ --with-default-libstdcxx-abi=new \ --enable-libmpx \ --disable-multilib \ --with-system-zlib
Step 7:
make
This step takes so long (about 2 hours) 😀 be patient 😀
Step 8:
make install
Done! 😀 now we have gcc in $HOME/gcc/bin
