problem adding routing protocol

[res]

Hi,

Just to see how a routing protocol can be added onto NS3, I've just
tried with an example protocol --'newr' .

I've put newr in /src/routing , created helper files in /src/helper ,
and modified /src/wscript.

simple-point-to-point-newr.cc is in /scratch.

Here goes the error

[root@localhost ns-3.2]# ./waf

Is there any other modification that I have to make?

Please help if possible.

For starters, these lines suggest that your new header files are not
being included.

If your simple-point-to-point-newr.cc already includes
"ns3/helper-module.h", then you need to add your new helper header file
to src/helper/wscript. Or else, you can just directly include your new
header files at the top of your simple-point-to-point-newr.cc file.

I can't tell the error -- seems like the kind of thing you might just have to bang your head against till you get it....
 don't you also need to modify wscript in the helper folder  include your new file?

After adding the helper file to src/helper/wscript, it worked fine.
Thanks!!!!
