Prerequisites:

• A CentOS 7.9 system
• Sudo privileges

🔨 Installation Steps:

1. Install Dependencies:
   • Ensure your system is up-to-date and equipped with all the necessary development tools:

     sudo yum update -y
     sudo yum groupinstall -y "Development Tools"
     sudo yum install -y gcc gcc-c++ make bzip2 tar glibc-devel glibc-static libstdc++-static libstdc++-devel libgcc libgomp kernel-headers kernel-devel perl-Data-Dumper perl-Thread-Queue python3
     

2. Download GCC Source Code:
   • Grab the latest GCC source code from the official GNU site:

     wget https://ftp.gnu.org/gnu/gcc/gcc-13.2.0/gcc-13.2.0.tar.gz

3. Extract Source Code:
   • Unpack the source code and move into the directory:

     tar -xf gcc-13.2.0.tar.gz
     cd gcc-13.2.0

4. Preparation:
   • Get additional prerequisites needed by GCC:

     ./contrib/download_prerequisites

5. Create a Build Directory:
   • It’s recommended to compile GCC outside of the source directory:

     cd ..
     mkdir gcc-build
     cd gcc-build

6. Configure the Build Environment:
   • Set the configuration for the build:

     ../gcc-13.2.0/configure --prefix=/usr/local/gcc-13.2.0 --enable-languages=c,c++ --disable-multilib --disable-bootstrap --with-system-zlib

7. Compile GCC:
   • Start the compilation process using all available cores:

     make -j$(nproc)

8. Install GCC:
   • Once compilation is complete, install the new GCC version:

     sudo make install

9. Update Environment Variables:
   • Add the new GCC binary to your PATH for easy access:

     echo $PATH
     export PATH=/usr/local/gcc-13.2.0/bin:$PATH
     export LD_LIBRARY_PATH=/usr/local/gcc-13.2.0/lib64:$LD_LIBRARY_PATH
     sudo ln -sf /usr/local/gcc-13.2.0/bin/gcc /usr/bin/gcc
     sudo ln -sf /usr/local/gcc-13.2.0/bin/g++ /usr/bin/g++
     source ~/.bashrc
     source ~/.bash_profile

   • Consider adding these lines to ~/.bashrc or ~/.bash_profile.
10. Verify Installation:
    • Ensure the new GCC version is correctly installed:

      gcc --version
      /usr/local/gcc-13.2.0/bin/gcc --version

🥳 Congratulations! You’ve successfully installed GCC 13.2.0 on CentOS 7.9. Enjoy the cutting-edge functionalities of your updated compiler!
