100% agreed on the kdbg and insight topics;
Concerning the -g flag, one can also configure ns2 with debugging support, eg: ns2> ./configure --help ns2> ./configure --enabled-debug (for c++ debug) ns2> ./configure --enabled-debug --with-tcldebug=../tcl-debug-2.0 (for c++ and tcl debug) ******** Incidentally, this is exactly the kind of ns-users aids that would be most useful for NS2 newcomers. For this, the NS2 wiki is the perfect place for NS2 beginner users to post their success stories / detailed HOW-TOs / tried-but-failed experiments __based on their own learning experiences and lerning curve. As such, and this is not the first time I make this call for volunteers, ___PLEASE CONTRIBUTE TO THE NS2 WIKI___. For instance, check http://mailman.isi.edu/pipermail/ns-users/2006-January/053560.html; I've had exactly __0__ responses for this call for volunteers! However, I've spent a lot of time doing my own help pages for only the benefit of the NS2 community, and I'm sure that I've already helped a lot of persons already. http://tagus.inesc-id.pt/~pestrela/ns2/ Thus: - Have you seen any good tip in the ns2 mailing list? Did it worked? Then put your detailed guide in the wiki. No need to be very formal, just give all the important details! - What, it didn't worked? Start by putting the things that worked on the wiki, search a bit, ask for help in the mailing list, then when its solved put the whole story in the wiki. - Etc etc etc. To conclude, I sincerely fail to see why the NS2 community is so different from other programming communities, which are probably as hard to get into as ns2. Of course that we have our TCL/C++/bindings problems, but "they" probably have their problems as well that we don't even imagine of. I sincerely think that is users contribute, someday we'll be able to have something similar to this wiki, for example: http://developer.valvesoftware.com/wiki/Category:Programming http://developer.valvesoftware.com/wiki/Compiling_under_Linux Comments?
