This appears to be set course work for a course in India and people have posted about this problem in the past.

Have a search around for "Agent/myUDP create _o82" (a string I selected because I figured it would be unique enough to lead to info on people having encountered the same problem). You will find at least one potential solution.

Hi
I have taken this step:
cd ns-allinone-2.35/
patch -p0 < myevalvid2_ns235.patch
https://drive.google.com/file/d/0B7S...ew?usp=sharing
export CC=gcc-4.4 CXX=g++-4.4 && ./install
cd ns-2.35/
sudo make install
cp ns ns235-evalvid2
sudo cp ns235-evalvid2 /usr/local/bin/


but when i run export CC=gcc-4.4 CXX=g++-4.4 && ./install
the following error is coming..

Tcl is not part of the ns project. Please see www.Scriptics.com
to see if they have a fix for your platform.

Re #5.

? May be you used 'sudo' (or a GUI tool) for the unpack of ns-allinone-2.35.tar.gz ?
( No sudo for any ns2 command.
EDIT : (Except 'sudo cp [ns-name] /usr/local/bin/' and 'sudo make install' ).


Please delete all ns-allinone-2.35/ and do :
$ tar xvf ns-allinone-2.35.tar.gz

Dear knudfl,
Thanks sir,i do this command:$ tar xvf ns-allinone-2.35.tar.gz
and after doing "make install"
i am getting this
for d in /usr/local/man/man1; do \
if [ ! -d $d ]; then \
mkdir -p $d ;\
fi;\
done
/usr/bin/install -c -m 755 ns /usr/local/bin
/usr/bin/install: cannot remove ‘/usr/local/bin/ns’: Permission denied
make: *** [install-ns] Error 1
what will i do?

Re #7.

The 'make install' command is $ sudo make install : See #4.

As post #6 suggests, it's recommended to do like $ sudo cp ns-evalvid2 /usr/local/bin/
Also included in post #4.

Dear knudfl,thanks for reply
i run $ sudo make install
but i am getting this
for d in /usr/local/man/man1; do \
if [ ! -d $d ]; then \
mkdir -p $d ;\
fi;\
done
/usr/bin/install -c -m 755 ns /usr/local/bin
/usr/bin/install -c -m 644 ns.1 /usr/local/man/man1
what will i do??!!!!

Dear knudfl,
Although following the above steps, but it remained the same error "invalid command agent/myudp" when i run ns235-evalvid2 be.tcl
I do not know what to do, please I want some advice to solve this problem.
thanks and Best regards

I can tell you this much,

the file named "be.tcl" at line 24 is causing the problem. perhaps a bad naming or invalid prams being passed into function, OR a bad function call itself.

key words that indicate this are highlighted but that is just me giving you my best guess.

you weren't kidding about it being from the PAST. this was posted in 2008 same exact problem. LMAO
