    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
    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)

      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 , use gcc-5 instead of gcc-4.8 and so on
