Hi, I'm trying to use EDCA_ns2_28-v1-0-2.tgz on ns2.33. But after doing all the modifications and running make ,I got this error in the Makefile: "*Makefile*:76: ***les commandes commencent avant la première cible. Arrêt." In some forums,it's said to be a problem of tabulations ,i have rewrite the lines several times using tabulations but i have always the same error!!!!! Can anyone help me please?it's soooooo urgent!!! thanks in advance
