Hi to everybody, 

I am trying to run omnet via terminal in order to develop automatic simulations, but i can not. When i use the IDE, everything works fine but via terminal i always receive the same message "<!> Error in module (cCompoundModule) DarpTestNet (id=1) during network setup: Class "ChannelControl" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel()"

I was looking for a solution and most of them are focused on the omnetpp version. I am using omnetpp-4.4.1 with inetmanet-2.0 under Xubuntu 14.04-64 bits. I am using an omnetpp.ini file with only the general configuration. 

The debugger gives me the following trace: 
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
You should now probably be running the simulation under gdb or another
debugger. The simulation kernel will now raise a SIGABRT signal which will
get you into the debugger. If you are not running under a debugger, you can
still use the core dump for post-mortem debugging. Once in the debugger,
view the call stack (in gdb: "bt" command) to see the context of the
runtime error.

<!> Error in module (cCompoundModule) DarpTestNet (id=1) during network setup: Class "ChannelControl" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel().

TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?

Any help would be very appreciated.

There are two possibilities, the “run” that launch the simulation is incorrect or the run_inet file is incorrect.

Thank you Alfonso,

I don't know exactly how to fix the run_inet. If i take a look on the "run" file in my folder i can see this content:

-----------------------------------------------------------------------------
#!/bin/sh
../../../src/run_inet $*
-----------------------------------------------------------------------------

In run_inet this is the content:

-----------------------------------------------------------------------------
#! /bin/sh
DIR=`dirname $0`

if [ -x $DIR/inet -o -x $DIR/inet.exe ]; then
  $DIR/inet -n $DIR/../examples:$DIR $*
else
  opp_run -l $DIR/inet -n $DIR/../examples:$DIR $*
fi

-----------------------------------------------------------------------------

Any suggestion?

Best regards,
Fran

The “run” is erroneous

 

It should be

../../../src/run_inet -n .:../../src $*

I recompiled everything and modified my "run" too, but i have the same error, the debugger shows that:

If i run the debugger with args (gdb --args opp_run -l ../../../src -n ../../../src:../..)

The option –l is the library

-l ../../../src tries to load the library libsrc.so

The library in inet is libinet.so, it should be

-l ../../../src/inet

It is working now, thank you very much Alfonso.

Where can i find all the possible arguments for the opp_run, for example to modify the simulation speed.

Thanks in advance,
Francisco

By default, if you send the simulation with cmdm the simulation is executed in express, if you want to increase the speed you need to compile all in release mode.
