Error: cannot resolve module type `Router'

[Alberto Cortés]

Hello, I'm an Omnet++ newbie.

I have this simple ned file:
#####################
import inet.nodes.inet.Router;

network scenario01
{
submodules:
router0: Router {
parameters:
gates:
pppg[1];
}

router1: Router {
parameters:
gates:
pppg[1];
}

connections:
router0.pppg[0] <--> {delay=10ms;} <--> router1.pppg[0];
}
####################



And this simple omnet.ini file:
###################################
[General]
network = scenario01
###################################



I make the Makefile with:
##################
alcortes@bat:~/local/learning/omnetpp/test; opp_makemake -f --deep -O
out -L/home/alcortes/local/omnetpp-inet/inet-framework-inet-d98efa8/out/gcc-debug/src

opp_makedep -Y --objdirtree -I. -f Makefile -P\$O/ -- ./*.cc

##################
(I have take this opp_makemake options from a successfully compilation
and execution in the omnet++ IDE, but I can't find how to use
opp_makemake with the INET framework in the documentation)


I compile and run and get the following error:
###############################

###############################

I'm using:
- omnetpp version 4.0
- inet framework d98efa8 (2009-11-28 )

I can run and watch the omnet and inet framework demos, so I think
they were successfully installed.

I think the error comes from not knowing how to tell opp_makemake to
find the INET framework libraries. Any hints?

Sorry to everybody I'm going to answer this question in Spanish


Te contesto en castellano,

Es un problema de rutas, no puede encontrar las rutas a los ficheros ned que
est嚙編 usando (Router.ned). Puedes a嚙窮dir la de b嚙編queda en el fichero ini
para indicar donde tiene que buscar los ficheros .ned mira en la seccion 9
del manual "Specifying the NED path"

De todas maneras ten cuidado con la librer嚙窮 inet.so en unix o inet.dll en
windows. Es en esa librer嚙窮 donde est嚙�el c嚙範igo ejecutable del router y por
lo tanto tambi嚙緯 tienes que indicar como acceder a ella.

Lo mas sencillo, si tu red usan el c嚙範igo del inet-framwork, es que pongas
tus ejemplos dentro del directorio examples y copies el fichero run de
cualquiera de los otros ejemplos. Con eso te garantizar嚙編 que tus ejemplos
encuentre la librer嚙窮 inet.so y los ficheros ned.

Fixed!

I will translate (an abstract of) Alfonso's answer to english and
explain how I solved the problem:

Alfonso wrote something like this:
##########
You have a problem with the NED_PATH. Learn more about the NED_PATH
at the section 9 of the manual: "Specifying the NED path".

You can define the NED_PATH inside the ini file. Take care to
include all the INET neds files in the NED_PATH.

The easiest way to go with the INET framework is to include your
code in the examples directory of the INET framework and reuse some of
its ./run files.
###########

Alfonso was right, I had a problem with the NED_PATH. I overwrote the
NED_PATH using the ned-path comfiguration option in the ini file:

###################################
[General]
network = scenario01

ned-path = /home/alcortes/local/omnetpp-inet/inet-framework-inet-d98efa8/src/;.
###################################

Notice the . after the INET framework directory, that way I can also
use my own ned files in the current directory.

PS: I prefer this solution to moving my code to the INET framework
example dir, because I don't like to use the INET framework examples
dir as my playing ground.

PPS: ¡Gracias Alfonso!

I encountered the same problem. However when using the NED_PATH with
inet.nodes.inet, I got the following error "declared package '
inet.nodes.inet' does not match expected package"
Any idea how to overcome this?
Amit.

Fixed!

No idea, sorry, it looks like you are not facing the same problem that I was.

Please note that I posted the full contents of all my files and the
Inet version I was using.

Have you try to reproduce my problem instead of yours?, you will
notice the differences between them and you will realize why my
solution didn't solve your problem.

Thanks to an offline correspondence I had with Alberto, who
recommended me to read carefully on Omnet++ packages, I overcame this
problem.
It appears that in the NED_PATH you need to put the directory where
the the root "package.ned" file is located.

So I made a step forward toward the batch execution of my project
(that uses INET modules).
My next problem is that I get the following error

<!> Error in module (cCompoundModule) ... (id=1) during network setup:
Class "FlatNetworkConfigurator" 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().

Any help will be appreciated,

Amit

Hi All,
I continued researching for a solution and I would like to report the
group about my findings:
It seems that there was a problem in earlier versions of Omnet++
related to "Switching a shared library based model to release mode
from debug prevents the running of model" But it was reported that it
was solved in version 4.2. I am using the latest Omnet++ version (as
of today 4.2.1), so it should not be this issue.

I also checked my script on a unix machine, and ... it works! So the
problem I encounter is only under Windows when invoking the script
under mingw32 (while I can run my simulation successfully from the IDE
even in command line).

Anyhow, I need this for a unix env. so for me this is good enough.

Thanks again to Alberto for his hint.

Amit.
