First of all, you're missing a comma (",") between the two arguments given
to the base class of PingHeaderClass(), PacketHeaderClass().
Secondly, please take a look at the ns-2 manual, chapter 12: "Packet
Headers and Formats": under 12.1, it clearly states that you MUST call
bind_offset() in the constructor to bind the offset address of the packet
header in question. Clearly, you did not do that.
Apart from 12.1 which can be found here
http://www.isi.edu/nsnam/ns/doc/node128.html
please make sure you also followed 12.1.1 "Adding a New Packet Header Type":
http://www.isi.edu/nsnam/ns/doc/node129.html
If there are other errors remaining, please first take the time to look up
*all* relevant parts of the manual prior to re-posting. Should you still
need to post, always include compiler error messages.
Cheers,
