problems installing the SOT sample files by Isidor Kouvelas in N

["KJ CURRAN" <kj.curran@ulst.ac.uk>]

To those who have attempted to install the SOT belonging to Isidor 
Kouvelas in his paper on 'Network Adaptive Continuous Media 
Applications through self organised transcoding'.

I have changed most of the files in the SOT README file  but I only
get this far. do you have any ideas why this might happen. I also
enclose a list of the various changes that I have made to the files
etc at the end of this. 

here's the error message:

BDL=1  -I. -I../tclcl-1.0b8 -I../otcl-1.0a4 -I../tkbox/include

________________________

To get this far I changed packet.h by adding:
 #define PT_SOT  "sot"

I changed tcl/lib/ns-packet.tcl to :
 { SOT off_sot_ }

I changed rtp.h to

 double ntpts_;

 and futher down I added

 double& ntpts() { return (ntpts_); } 

I also changed rtcp.cc :
 In function RTCPAgent::sendpkt()
 rh->ntpts() = Scheduler::instance().clock();

I added the following files to the ns Makefile :
 sot.cc			SOT implementation
 transcode.cc		Transcoder class
 drop-tail-loss.cc	Queues that do random drop and byte accounting

and I added the tcl files to ns-2/tcl/ex directory.

Thanks for your time
