DeleteHello Sir...
ReplyDeleteI 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:

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
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
Deleteplease do the following steps
Delete$] 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
u dont have to press enter... just enter "gcc-" and press "tab" button on keyboard... U will get all the options
