While adding a transport layer protocol in ns-2.31 in ubuntu 14.04, I am coming across the following error that I have been unable to resolve.

"make: *** [dtsncc/dtsncc-cache.o] Error 1" (screenshot available at)


I have followed the instructions written in the readme file. I have ns2.31 working + fixRT + ns2measureDCF. I have modified the following files before the 'make'.

  • Packet.h
  • cmu-trace.cc and cmu-trace.h
  • priqueue.cc
  • ns-default.tcl
  • ns-packet.tcl
  • Makefile

A copy of the above mentioned files along with the compiler version are available at https://www.dropbox.com/sh/8mc9nyimljat42k/AAA4fBEkEEu7DyhGGxSd_9y3a?dl=0

Still I'm coming across the error in the attachment. The output of the make command can be seen at:


The code for the protocol is available at https://www.dropbox.com/sh/1ngygz5nuxl0885/AAA3u1vnKIk9wZRf65GupUvCa?dl=0

I would really appreciate if someone can help me ASAP. I dont have alot of time to spare and have been trying to resolve this issue for the last 7 days. Also, all the contents of the above link can be found at



Your "error output" shows warnings, no errors.

Depending on the object order in the Makefile.in, I get two different errors. The readable results are here, dtsncc_14.Jul.2016_errors.txt https://drive.google.com/file/d/0B7S255p3kFXNZFlraEZXQWdCaGM/view?usp=sharing

fixrt/fixrt.cc:850: error: ‘HDR_NDTSN’ was not declared in this scope

Edit 01 : I created a patch with all the changes, including ns231_gcc44.patch, ns2measure-2.31-070909.patch : dtsncc-all_ns231-01.patch https://drive.google.com/file/d/0B7S255p3kFXNZzdzNGFBQXBTcW8/view?usp=sharing

Please try with the Ubuntu g++-4.4 compiler: export CXX=g++-4.4 && ./configure && make

EDIT 2 : The error output with Ubuntu 14.04 - 64 → https://drive.google.com/file/d/0B7S255p3kFXNdmRiVGFsSlBBYnM/view?usp=sharing

EDIT 3, 26Jul : Got your "ns-2.31dtsncc". Replaced the header dtsncc/dtsncc.h with this https://drive.google.com/file/d/0B7S255p3kFXNMUpGUWx2STF0M0k/view?usp=sharing , and got some further with 'make'. Which leaves us with this error : wnd_' was not declared in this scope

ndtsn/ndtsn.cc: In constructor `NDtsnAgent::NDtsnAgent()':
ndtsn/ndtsn.cc:48: error: `wnd_' was not declared in this scope

  • The error at link dtsncc/dtsncc.cc:690: error: ‘class AODV’ has no member named ‘get_num_hops’ I was able to resolve it by adding the following in aodv.h file: At location class AODV: public Tap, public Agent { /* * make some friends first */ friend class aodv_rt_entry; . . . . public: AODV(nsaddr_t id); void recv(Packet *p, Handler *); void tap(const Packet *p); int get_num_hops(nsaddr_t node_id, nsaddr_t dst); – Umair Chaudhry Jul 15 '16 at 1:10
  • I have not been very fortunate with fixrt/fixrt.cc:850:29: error: ‘HDR_NDTSN’ was not declared in this scope hdr_ndtsn *th = HDR_NDTSN(p); – Umair Chaudhry Jul 15 '16 at 1:11
  • I was given this folder by my advisor and he has asked me to add it to ns-2. The folder is at: folder The error that I am is as follow: queue/priqueue.cc: In member function ‘virtual void PriQueue::recv(Packet*, Handler*)’: queue/priqueue.cc:98:19: warning: unused variable ‘dtpah’ [-Wunused-variable] struct hdr_dtpa *dtpah = HDR_DTPA(p); ^ make: *** [queue/priqueue.o] Error 1 Details can be seen at error Please help. – Umair Chaudhry Jul 20 '16 at 4:58
  • Please see my edited answer, EDIT 3, 26 July 2016. – Knud Larsen Jul 26 '16 at 14:31
  • So all I need to do is replace dtsncc/dtsncc.h with the dtsncc.h that you have replaced and do make clean followed by make right? – Umair Chaudhry Jul 28 '16 at 15:11
