# 60.

1) Install Ubuntu 12.04
2) sudo dpkg -i myevalvid2-ns-2.28-ubuntu10-1_i386.deb : Post #46.
3) If you want to build your own 'ns' executable : Post #46.
But that's actually not required. Everything is compiled into one file: 'ns'.
And that is what you get from the package in 2) : /usr/local/bin/ns-***

@knudfl i want use mp4trace for sctp protocol but it supports only rtp/udp /ip what should i do as my thesis is already running?

I have the same problem of vijayukanirs in post #49. (invalid command name "Agent/myUDP") for ubuntu 12.04
I am really confused! please help me

# 63, @arr30n : Welcome to LQ.
It means that you are using an executable 'ns' with no "myevalvid".

The causes can be : 1) You are using the wrong 'ns'.
2) No myevalvid patchings / edits were added to ns-2.28 .
3) Your editing is OK, but you have a failed build.

@knudfl Sir can we have the exact steps to follow for 12.04. ubuntu for installing ns2 +evalvid because in most cases we have failed build. is it possible for us to have such clear step by step instructions

# 65 .
That's what post # 46 is about.

The compilers gcc41, g++41 , post #47 here ..
http://www.linuxquestions.org/questi...532/page4.html
Note : The compilers are for a 32bits (i686) OS : $ uname -m <Enter>

SOLVED!
it just needs "sudo make install" command after make.
I hope this will be helpful for who has encountered this error for integrating evalvid in NS-2.35, ubuntu12.04 : invalid command name "Agent/myUDP"

# 67 .

Looks like it resembles 1) in post # 64.
I.e. you can only have one executable 'ns' in /usr/local/bin/.
The trick is to rename all 'ns' to ns-<newname>.
( I have 70 differently named 'ns' in /usr/local/bin/ ).
The "myevalvid ns" could be 'ns-myevalvid2' like the executable
in the package "myevalvid2-ns-2.28-ubuntu10-1_i386.deb".
(myevalvid2-ns-2.28-ubuntu10-1_i386.deb works perfectly with Ubuntu 12.04 .
→ → Post # 46.)
Using a "ns-myevalvid2" executable : $ ns-myevalvid2 file.tcl

I have downloaded EvalVid2.7 from its official website(http://www2.tkn.tu-berlin.de/research/evalvid/).
but i encountered errors when making it for ubuntu12.04. The following is one part of the error:
I have used Evalvid2.7 binaries so far but now i want to modify the code.
Is there anyone has successfully installed evalvid2.7 on ubuntu12.04?

Then I compiled the NS (ns-2.35 in Ubuntu 14.04 LTS) with necessary changes and everything worked fine. Then I tried to
run a tcl script .... And the error is :
(_o84 cmd line 1)
invoked from within
"_o84 cmd set_filename rd_a01"
invoked from within
"catch "$self cmd $args" ret"
invoked from within
"if [catch "$self cmd $args" ret] {
set cls [$self info class]
global errorInfo
set savedInfo $errorInfo
error "error when calling class $cls: $args" $..."
(procedure "_o84" line 2)
(SplitObject unknown line 2)
invoked from within
"$null1 set_filename rd_a01"
(file "be_a01.tcl" line 31)


Why this error is coming ?? If anyone knows please help.

Thanks,

Re post #70, @hbenlabbes : Welcome to LQ.

Note : "be_a01.tcl" is a `myevalvid2' file.
Note 2 : The `myevalvid2' code can be compiled with g++-4.4: sudo apt-get install g++-4.4
