[Ns-developers] Documentation on Tracing needs a change

The first documentation you mention is correct for the current version of
ns-3-dev, but the tracing documentation was missing the declaration of
"ascii". It should have been,
pointToPoint.EnableAsciiAll (ascii.CreateFileStream ("myfirst.tr"));
I just fixed the tutorial to reflect this.
I have no idea how your "correct" version below could possibly work. As far
as I know, there has never been a PointToPointHelper method with a signature
Perhaps you are using an older version of ns-3 (than last month's ns-3-dev)
and really meant to type,
ascii.open ("csma-broadcast.tr", std::ios_base::binary |
Note the differences in the last line. If you are using an older version of
ns-3 (for example, ns-3.7), you should really be using the version of the
tutorial that works with that version of ns-3. The tutorial for ns-3.7
(that can be found on www.nsnam.org) tells you to add these lines of code,
which should work just fine:
Again, note the last line.
This change is relatively new, so I see how you could get messed up if you
downloaded your ns-3-dev before the tracing change was pushed and then began
working on the (new) tutorial afterwards. But ns-3-dev is the development
branch, so you have to expect such things. If this is the case, and you
pull the latest ns-3-dev, you will see the code and tutorial back in sync.
By the way, ns-3-reviews is probably not the best place to post this kind of
message. If you think you've found a bug, even a documentation bug, you
should either file the bug in www.nsnam.org/bugzilla or ask about it on
ns-3-users at googlegroups.com or if you are ready for more dense info, on
ns-developers at isi.edu, I think.
