some of the simple errors of this kind can be resolved by modifying the code little bit (like using type casting). Otherwise we have to change the gcc version if we face LOT of such errors during compilation.
This may be due to the wrong path/environment setting in the profile of that particular user (.bash_profile – which is a hidden file – which sets some environment variables -ns2 installation will add few lines in to it – or you may be set some thing wring in that profile )
#ls -a will show all the files including the hidden ones.
try after removing the following lines or put ‘a #’ in front of these lines . (particularly I am having doubt in the first line – it seems to be changing the cpp environment – so the default gcc will be ignored)
If you are able to compile the same thing successfully while login as another user, and can not do the same in a particular user account, then certainly it will be related with user right on a particular directory/command and some environment settings like the PATH environment variable. Just explain each step of your installation/compilation.
