Inetmanet Error

[chandran AR]

I just tried creating my own mobility n/w while doing so, i just
modified exiting file
into my own & put into the new folder -- which is created under src
folder...

When doing so , I just modified the
ChannelControl into IChannelControl & (corresponding files .cc, .h
files also.)
when i trying to execute the prj...
it prompts me an error,,,, saying that


. "error in module (ISnrEval80211) IMFNET.host[0].wlan.snrEval
(id=22) : Could not fine IChannelConrol Module. "


ISnrEval80211 this is actually SnrEval80211.... I am trying for along
time but I COuld not find the
problem...

PLease help me to solve this problem...

[Rudolf Hornig]

Are you sure the new file is included in the makefile (i.e. linked into the project)?
Open src/Makefile and check wheter your file can be found in the OBJS variable.

If not: re-run make makefiles from the root to regerate the file.
If it contains, then check your cc file if it contains the Define_Module macro with the correct (changed) calssname.

Reading a little further... This is a NED error. You have moved the file into a different directory (i.e. you have implicitly changed its package too.) Are you sure all package names and import fdeclarations are correct?

[chandran AR]

Th files are added correctly into the makefiles as follows.

 

OBJS = \

$O/aidemo/channels/IChannelAccess.o \

$O/aidemo/channels/IChannelAccessExtended.o \

$O/aidemo/channels/IChannelControl.o \

$O/aidemo/channels/IChannelControlExtended.o \

$O/aidemo/pingapp/IPingApp.o \

$O/aidemo/snreval/IBasicSnrEval.o \

$O/aidemo/snreval/ISnrEval.o \

$O/aidemo/snreval/ISnrEval80211.o \

 

2. Name contradiction is also not there and the files are and Under Define_Module(IChannelControl); is als correct..

 

3. then i have not moved any files , i just copied the  files  changed name into differet locations.

 

please specify where i might have done a mistake.....

Ok, not moved..I was suggesting that if you have copied NED files to a different directory then you have to modify the package definitions and also import statements. 

Please attach/paste ISnrEval80211.ned and IChannelConrol.ned. I'd love to see them.

Hi, I have taken a look at your project. About the your current issue:

- You have done the renaming/namereplace a little bit too eagerly. You have changed also the following lines:
IChannelControl.cc:
    IChannelControl *cc = dynamic_cast<IChannelControl *>(simulation.getModuleByPath("channelcontrol"));
    if (!cc)
        cc = dynamic_cast<IChannelControl *>(simulation.getModuleByPath("channelcontrol"));


IChannelCOntrolExtended.cc:
cc = dynamic_cast<IChannelControl *>(simulation.getModuleByPath("channelcontrolextended"));
    if (!cc)
       cc = dynamic_cast<IChannelControl *>(simulation.getModuleByPath("channelcontrolextended"));

The bold stuff is the name of the channel controller object at the top level and not its type... It should not be replaced...

This will fix your current issue BUT:
As soon as you fix it, you will face an other one:
The mobility moules are also expecting a channel controller at top level, but they are hardcoded to expect a type of ChannelController. Your module now contains an IChannelController, so they will not find it and you will get another
error about a missing channelCotroller node... So you have to rename/copy the whole mobility stuff too...

In general, I don't know why do you do this copy/rename stuff, but this is a bad idea. To make everything work slowly you will rename each module step by step (because of the dependencies) and will get a second independent copy of all the code inside the src folder which is a waste of time and effort...

If you want to do minor tweak for your research you can do it directly in the original classes. If you want to add new functionality, then duplicating the already exisitng code is not the way to go. In this case fork the inetmanet project on github and do the development in your own repo...

Thanks for your reply.

 

I missed to attach the file INic80211 as  created under the  same existing Folder Structure : inet.linklayer.mf80211.

Now i am attaching that file too. please

Checked the project and failed:

In IMFMobileHost.ned i found:

import inet.linklayer.mf80211.INic80211

In INET-FW there is no such file in src/linklayer/mf80211

Are you sure you have copied all modified files into the aidemo directory that was sent to me?

Hi, I went off list not to pollute the mailing list too much.
I cannot see anything from the files. If you zip your directory (src/aidemo) and send it, I will try to take a look at it.

Right now, I have no idea what the problem is.

Hi  Rudolf Hornig ,

 

                          Thank you so much for your Suggestion ,effort and reply. I will try modifying the existing code.

[Shaikha Al-Khuder]

"Could not find ChannelControl module with name 'channelControl' in the top-level network"

when using :**.wlan[*].typename = "Ieee80211Nic"

How to fix?

[Alfonso Ariza Quintana]

Have you check that exist the module cannelControl in your model?

I can't find the problem, the module channelControl is defined.

The usual problem is that the capital letter, the name must be exactly channelControl.

When I write as you wrote it I get this error:

imported NED type not found: ‘inet.world.radio.channelControl'

[Alfonso Ariza Quintana]

The module is ChannelControl or, in your case IdealChannelModel, but the name of the module in the network must be channelControl
