Re: [ns] problem when make is used

[siva rupesh ss]

Hi rashmi,
  First thing is that you should save the "ex-linkage.cc" in
a newly
created directory(for example "newproto") under ns-2.31 directory

  Then add a line in Makefile.in which is in ns-2.31
directory
in OBJ_CC    like

   newproto/exlinkage.o \

Then run ./configure  and make  .  under the ns-2.31 directory

The reason for the error  messages u specified may  be..
1.If u r not running "make" under ns-2.31  directory
2.If the path u specified for the source may not visible to "make"...

Hope this may help you,
Rupesh

[ns] problem when make is used

[rashmi bhat]

Hey everyone,
Im trying out the example on "NS by Example" site. There's one example for
OTcl linkage where the following instructions are said:


   1. Download "ex-linkage.cc"
   file, and save it under the "ns-2" directory.
   2. Open "Makefile", add "ex-linkage.o" at the end of object file list.

   3. Re-compile NS using the "make" command.
   4. Download the
"ex-linkage.tcl"
   file that contains "MyAgent" testing OTcl commands. (see Figure 22 for the
   input script and the result)
   5. Run the OTcl script using command "ns ex-linkage.tcl".

I searched the archives in here & did a few things. I saved the file
"ex-linkage.cc" under the ns-2.31 directory. I added "[tab]ex-linkage.o \"
in the "Makefile.in" file under the ns-2.31 directory. Then i did "sudo
./configure". It did some checks. Then when i did "make clean" and "make",
it says

make: *** No rule to make target `clean'.  Stop.

make: *** No targets.  Stop.

respectively. Anybody knows what I am doing wrong?(or if at all i did
anything right!) Awaiting suggestions & help.

 Hi Marcello,

 The code is working fine now. No segmentation fault.
 However, I just ran a 100 node  (1000x1000 area) - Random Waypoint
 model,  50 CBR/UDP connections of 1 packets/sec  and mean node
 speed 10 m/s  and  I see a increase in data packet loss from 28%
 (when i used the old AOMDV code) to 37% (when i use the new  
 code)  ..
 since I had commented the part where it drops HELLO packets in
 nb_delete() ,  I did the same in the new code, but it doesn't
 help. :(  anyway..i will figure out what the problem is. :)
 hey ..btw... the route table dump function is an awesome addition.
 I had added a similar function when I was using Ahmad Kayyat's
 code for ns 2.29 :) ..

Re: [ns] Problem about AOMDV

[Marcello Caleffi]

Hi Ying,
I guess you have downloaded a malformed path file.
Please try to download a fresh ns-2 source tree (2.32 version) and to  
apply the last patch (online from a few of days) again.

Let me know what happens.
