[ns] Problem when adding a new TCP agent

[Ghassan Akrem]

Hi friends..
 
I wrote a sub-agent of TCP, that means I put new files TCP-xxx.h, TCP-xxx.cc in the folder of TCP, and modified tcp.h, tcp-sink.h and tcp-sink.cc. Then added  TCP_xxx.o to OBJ_CC in makefile.in, and then do "make"

I try to use the agent with "New Agent/TCP/xxx", but it seems un-recognizable.
what's possibly the problem? 

Please any one can help or have some ideas?
 
Thanks alot
