Re: [ns] how to use "gdb" to debug an error in .tcl format file
- In order to debug TCL files you should use tcl-deug. In order to debug the .cc files you need ddd (frontend for gdb). Here is detailed web info on how to use both, from Pedro Vale Estela: http://tagus.inesc-id.pt/~pestrela/ns2/ns2_debugging.html Also, at the ns web site there is some info on how to debug a TCL file while executing a C++ and vice versa. Check: http://www.isi.edu/nsnam/ns/ns-debugging.html and especially the part "Mixing TCL and C debugging".

[ns] problem with setting label of a node.
Hello Every one, Iam trying to set the label of a node with a string of length (approximately) 24 characters. But the nam tool is displaying only the first 19 characters. I would like to know if there is a limit on the length of the label that can be used? I would greatly appreciate if you can provide some insight into this problem. Thanks a lot, Raghu.
[ns] Problem in installing NS GNU/Linux (detailed question)
Hi, Here is a detailed question :). I hope that someone will help. I need to install a NS version for SPAN (http://pdos.csail.mit.edu/~benjie/span/span_ns.html) that go with otcl-1.0a6, tclcl-1.0b10, tcl8.3.2, tk8.3.2. I have installed all the above parts sucessfully and tried many NS versions. But no success. For example: when installing NS version ns-2.1b9a then it gives following error.
