Hello good people. I trust i will get help from my good friends here.

I came across this run error when I run omnet with Mixim framework. Anyone with idea of this error code? See attached screen and also below paste of same.
Am using omnetpp 4.6

Assistance highly appreciated friends.

That is probably a segmentation fault happening somewhere during the initialization of the modules.
You need to debug your simulation to find out where exactly it crashes.

Simple left click your omnetpp.ini and choose Debug as -> OMNeT simulation to start debugging your simulation.
The debugger will point out where the simulation crashes.
Look online for additional tutorials on debugging programs with GDB under Eclipse to find out more about how to use the debugger.

Thank you so much Mike. I am not so good in omnet, am still trying to learn and I have been trying to debug the output.
The current state of the simulation run is that it runs well until the end of simulation time with no above error. The previous error seems to have disappeared when i run the "omnetpp" from the mingwenv command.

From my simulation am expecting to see the output  "Castalia-statistics.anf" file so that i can browse through the different simulation output on throughput, delay, energy consumption etc. This Castalia-statistics.anf does not appear on the output of the run. Only Castalia-statistics.sca is generated which does not contain the output of the simulation.

Do you have an idea on why am not getting this?
See attached to give you an idea of what am getting and what am expecting

I thank you so much for taking time to help. I was so desperate with the problem

[Michael Kirsche]

You should always start OMNeT from the mingw command prompt under Windows.
Only then will all the necessary paths be set.

As for the missing anf file, this is simply a collection file where links to the actual output files (scalar files *.sca and vector files *.vec) are collected.
You can create it by clicking on the *.vec or *.sca files, the OMNeT IDE will offer to create an *.anf file, where you can select which *.sca and *.vec files you want to collect.
You can also manually create an *.anf file via the File -> New dialog.

Check the User Guide for the IDE - Chapter 9 for a detailed description: https://omnetpp.org/doc/omnetpp/UserGuide.pdf

Thanks so much Mike, I have learned that and appreciate. Learning is a continuous process and appreciated groups like this.

Let me try that and evert. My prayers that it works as expected 

Will get back to you on how it has gone

Thank you Mike. I have learned alot from your above email, you are great. I didn't manage to get the vector output but atleast I can get the scalars now and get the bar graphs.

I will now concentrate on simulating WBANs on omnet

Thank you so much
