i thought it's a patch problem so i removed all the files related to gcc4.3 because ns2.27 works with 4.1 but i got always the same error.please can anyone help me this is urgent !! thx

Welcome to LQ.
Actually there is no reason to remove ns-2.34.
You can have as many versions of ns-allinone-2.xx as you want,
installed at the same time. But not add anything to .bashrc / .bash_profile.


Which Linux OS are you using ?
