  4. Hello Sir...
    I have completed step2 successfully and i got a message like g++-4.8 is already the newest version (4.8.5-4ubuntu8).
    gcc-4.8 is already the newest version (4.8.5-4ubuntu8).
    The following packages were automatically installed and are no longer required:
    linux-headers-5.4.0-42 linux-headers-5.4.0-42-generic
    linux-image-5.4.0-42-generic linux-modules-5.4.0-42-generic
    linux-modules-extra-5.4.0-42-generic
    Use 'sudo apt autoremove' to remove them.
    0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

    But if I use gcc- command to check whether gcc-4.8 is installed or not, it is showing like ommand 'gcc-' not found, did you mean:

    command 'gcc-8' from deb gcc-8 (8.4.0-3ubuntu2)
    command 'gcc-9' from deb gcc-9 (9.3.0-10ubuntu2)
    command 'gcc' from deb gcc (4:9.3.0-1ubuntu2)
    command 'gcc-7' from deb gcc-7 (7.5.0-6ubuntu2)

    Try: sudo apt install

    I am Stuck in this step please help me out.

    Thanks in advance

    1. I faced the same problem check using the command "gcc-4.8 --version" and also grep using command 'dpkg -l|grep gcc' and you should be able to find it . hope this helps

    2. please do the following steps

      $] sudo nano /etc/apt/sources.list

      Include the following line
      deb http://in.archive.ubuntu.com/ubuntu bionic main universe

      $] sudo apt update
      $] sudo apt install gcc-4.8 g++-4.8

      for NS2.35 you can use gcc and g++ version up to 5.4
      if 4.8 isn't working try installing gcc-5 and g++5. then at the step where you modify the Makefile.in , use gcc-5 instead of gcc-4.8 and so on
