I tried attaching the 802.11e patch (from http://www.tkn.tu-berlin.de/research/802.11e_ns2/) to ns2.34 version. after i made the required modification I typed "./configure" then "make", "make clean" am getting the following error.. Makefile:66: *** commands commence before first target. Stop. I don't know where am going wrong. Does this patch works only on ns2.28?? or can i work with ns2.34 also?? Please help me friends..
