Ping Agent : Problems of Marc Greis’ Tutorial
Posted by Erwin on December 27, 2011
I came out with the Marc Greis’ tutorial especially in binding C++ and OTcl classes.
Even this was a very old tutorial, but it really interesting and much easier to follow.
I changed agent name to “Ping_e” instead of “Ping” to avoid conflict, and it turn out error as
/root/work/ping-test/ping_e.cc:65: error: âoff_ip_â was not declared in this scope
/root/work/ping-test/ping_e.cc:97: error: no match for âoperator>>â in âhdrip->hdr_ip::src_ >> *(Address::instance()->Address::NodeShift_ + 4u)â
I try to fix it based on NarcissusHuang‘s answers, but still come error.
so I make a little changes in ping header file (in my case ping_e.h) with only this line to declare off_ip_
int off_ip_;
at one line below “protected: int off_ping_e_;”, and in ping_e.cc file,
(hdrip->src_).addr_
as replacement from “hdrip->src_ >> Address::instance().NodeShift_[1]“.
As the result, I successfully use “make” command with no error, and run the tcl test program as well, even though with some warnings :D
I use NS-2.35 with Centos 5.7. Hope it can help to anyone who facing the same problem.
Thanks to Janaka Wijekoon for coding help.
Rgds,
Erwin.
