I have installed ns-2.33 on cygwin on xp.
while running simple example programs, I get error, $ nam: no display name and no $DISPLAY environment variable. I tried set it with export DSIPLAY=:0..0 it gives error $ nam: couldn't connect to display "0.0" I also tried startx before running programs, it gives following error, $ nam: [code omitted because of length] : no event type or button # or keysym while executing "bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D / 120) * 4}] units }" invoked from within "if {[tk windowingsystem] eq "classic" || [tk windowingsystem] eq "aqua"} { bind Listbox <MouseWheel> { %W yview scroll [expr {- (%D)}] units } bind Li..." can anybody figure out where the problem lies? I am new to ns-2 as well as linux environment so please..... Thanks in anticipation. Regards, ali balador,
