[Omnetpp-l] Problem with global simtime variable in INET

[Vitali Anselm]

Hello,

 

I am working with the last version of Omnet++ 4.0 and the last version of INETMANET (downloaded from github).

After installation of both programs, I have imported the INETMANET as "Existing project" into Omnet IDE.

First, I had problems to get the INETMANET working, because the INET.exe was not generated. I solved this problem by :

 

1) changing the C/C++ Build-->Build Directory under project properties to ${ProjDirPath}

2) setting the top directory INETMANET as "source location" under project properties-->Omnet++-->Makemake  , moreover let this top directory generate makefile and select the folowing parameters under "Options...":  Target--> Executable ,  Scope-->recursive make , Compile---> check the box "Compile object files for use in DLLs"

3) the same procedure with other parameters was done with the /src directory. made changes under "Options..." are:  Target-->Shared library and check the box "export this library for other projects"  , Scope--> deep compile 

 

After this solution of first problem, I could start every simulation example, e.g. net80211_aodv, without any errors...

But as soon as I import self-written directory including implementation of Ieee80216 stack, any simulation example can't be started anymore.

The following error is produced:

 

<!> Error during startup: Global simtime_t variable found, with value 2e-005. Global simtime_t variables are forbidden, because scale exponent is not yet known at the time they get initialized. Please use double or const_simtime_t instead.

Actually, there is no interconection between the original examples and the imported Ieee80216, because of that I don't understand why this error occur and how to find it.

I hope that someone of you can help me to solve this problem.

I thank you for your responses in advance.

best regards,

Please, send me the code and configurations files.

I just had a similar problem; it is not always easy to find where that
global simtime_t variable is. You might search where the value (2e-005,
0.00002 etc) occurs in the sources. If that doesn't help, put a breakpoint
into the

void SimTime::initError(double d)

function, src/sim/simtime.cc#60 -- this function is what raises the
exception. When breakpoint is hit, the debugger might be able to display
which variable the "this" pointer corresponds to in the program.

I have found a problem in the code. In the file Ieee80216Const.h

const simtime_t ST = 20E-6;
const simtime_t SIFS = 10E-6;
const simtime_t DIFS = 2*ST + SIFS;
const simtime_t MAX_PROPAGATION_DELAY = 2E-6;  // 300 meters at the speed of light

 

Must be

 

const_simtime_t ST = 20E-6;
const_simtime_t SIFS = 10E-6;
const_simtime_t DIFS = 2*ST + SIFS;
const_simtime_t MAX_PROPAGATION_DELAY = 2E-6;  // 300 meters at the speed of light

Hello,

I changed the lines in the file Ieee80216Const.h as you said, but it didn't
help unfortunately. Then I tried to find other matches to value "20E-6" and
there are several files, which also contain this value. These are:
Ieee80211-->mac-->Ieee80211Consts.h, Ieee80211-->mac-->Ieee80211gMac.cc,
mf80211-->macLayer-->Consts80211.h .
I tried to change the declaration variables, but then some errors occur
within the functions.
Could you take a look at these files and tell me, how to make changes? It
would be very kind.

Thanks a lot for your help.

regards,

Vitali Anselm

Hello,

I have compiled all, after changing the file Ieee80216Const.h and tried to
run the "handover" example from wireless directory and to my surprise there
is now another error :) Somehow, no one of the ned files in the src/
directory has a correct package declaration. Every ned file contain now
errors like : declared package "inet.applications.ethernet" does not match
expected package "ethernet" EtherAppCli.ned INET/src/applications/ethernet
line 18 NED Consistency Problem

But I didn't change anything in the ned files! It seems to be a magic
generating new types of errors every time :)

Some advices for it?

regards,

Vitali

Hello,

sorry for spaming the mailinglist... The last problem with the ned files is
solved. I had to "Clean Up NED files". I did the job.
Now the "handover" example runs withoot problems, but the net80211_aodv
opens the TkEnv and throws an error:

Error in module (cCompoundModule) Net80211_aodv.host[0] (id=3):
Submodule mobility: no module type named "inet.mobility.NullMobilty" found
that implements module interface
BasicMobility (not in the loaded NED files?), at
G:\inetmanet\src\node\adhoc\MobileManetRoutingHost.ned:109.

In this ned file there is the following entry on the line 109:
mobility: <mobilityType> like BasicMobility {
parameters:
@display("p=149,307");
}

Has it something to do with "like" which should not be used in 4.0 anymore?

regards,

Vitali

You probably set mobilityType="NullMobilty" in omnetpp.ini (btw, there's a
"i" missing -- maybe that's the problem?). This means OMNeT++ will look for
a module which looks like

simple NullMobilty like BasicMobility {
...
}

and obviously could not find it.

http://omnetpp.org/doc/omnetpp40/manual/usman.html#sec133 and
http://omnetpp.org/doc/omnetpp40/manual/usman.html#sec136, "Name resolution
with 'like'"

Where did you hear that? It's complete misinformation. "like" **IS**
supported. See the manual.

Hi,

how did you realize handover example, this is your module or the Mobility Fr. include it?

 

Thanks,

Hello Cem,

No, it is not my own module, but the existing module of INETMANET framework,
which can be found in examples/wireless/handover directory.

What are your NED folders? they should be "src" and "examples" ONLY.
You can check it in the project properties dialog or directly looking into the
.nedfolders file

(I'm guessing from the error message that you have src/applications in it...)
