@ toancnttk7d : Welcome to LQ.

This thread is about "olsr" only.
Please use the 'Report' button to ask for your posts to be moved to a new thread.
Your subject seems to be RTP.

And : Code tags must be used for code. That's the # button in the 'Advanced Editor'.
Or type [/code] at code text end, and [code] at start.
I.e. please edit your posts to use 'code tags'.

There are some errors in your text. Almost looks like tcl code ..

# 10
Quote:
invalid command name "Agent/RTP_v2"
Means : No RTP_v2 was compiled into 'ns' !

? The tcl file in #1 is "Multipath-MM-DSR+802.11e.tcl" :
http://sertel.upc.es/~maguilar/ns2_c...ial/node3.html

To use the file as is, the following changes are required in ns-2.33/ :
1) RTP_v2 : http://sertel.upc.es/~maguilar/ns2_c...ial/node2.html
2) MPEG2 send/receive http://sertel.upc.es/~maguilar/ns2_c...ial/node3.html
3) MM-DSR http://sertel.upc.es/~maguilar/ns2_c...ial/node5.html
? 4) ? MAC 802.11e from ?

So far I have got 1) and 2) installed into ns-2.27, which is the original tested version.
When everything works ( With the ns-2.27 mac 802.11 ),
I will then continue to ns-2.33 ...

Which Linux OS are you using ?

# 12 . The ns-2.xx/Makefile.in : ns-allinone-2.xx/ns-2.xx/Makefile.in

And the rtp stuff (one line) is added like this,
above @V_STLOBJ@, line 337 ( in ns-2.35 ) :
<TAB>rtp_v2/rtp_v2.o rtp_v2/rtcp_v2.o \
<TAB>@V_STLOBJ@
Note: The invisible <TAB> is a must : Cannot be replaced with <space><space>...)


ns-allinone-2.xx overview : A) ns-2.xx + the four ns dependencies,
1) tcl 2) tk 3) otcl 4) tclcl.
B) The other 6 applications are optional : nam xgraph cweb dei80211mr gt-itm sgb
.. and have nothing to do with the ns build.
And will thus not stop the "install" if they fail to build.
