"Class "inet::NetworkBase" not found" when running simulation from shell

[paintspot87]

I'm trying to run inet4.5/showcases/measurement/datarate from shell with the following command in Ubuntu which I grabbed from omnet IDE when it ran the showcase:

opp_run -m -c General -n ../../../examples:../..:../../../src:../../../tests/validation:../../../tests/networks:../../../tutorials -x inet.common.selfdoc;inet.linklayer.configurator.gatescheduling.z3;inet.emulation;inet.showcases.visualizer.osg;inet.examples.emulation;inet.showcases.emulation;inet.transportlayer.tcp_lwip;inet.applications.voipstream;inet.visualizer.osg;inet.examples.voipstream --image-path=../../../images -l ../../../src/INET omnetpp.ini

But when Qtenv starts I get the following error:

<!> Class "inet::NetworkBase" 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() -- during network setup

I get stuck here when trying to run simulations via the terminal, in the end, I will use Cmdenv to run several experiments.

This is the output when I try to run the same command but with -h classes flag. I'm thinking INET is not linked or something? I did try source setenv in the inet folder but it didn't help. I appreciate any feedback.

1. the opp_run -h classes will not give you any INET related classes, because those are in the INET shared library (libINET.so) which must be loaded manually with the -l switch, but your issue is not related to this. The INET library is fine
2. You copied the command line verbatim into the shell from the IDE. While the IDE indeed uses those parameters to start the app, the NED path is separated by ; (semicolons). Those semicolons are treated as command separators by the shell, so the second part of the command (which include the -l INET part to load INET) is not passed to opp_run causing the missing (not loaded) class definitions.

To fix this: put the NED package list after the exclusions (-x) into quotes. That will prevent the shell processing it and will pass correctly as a single parameter.

Or even better: type inet in that partiocular directory and the simulation will start (i.e. IDET has a starter script that does everything for you. There is no need to copy-paste commands from the ide.

That's being said, using the ; as a separator can cause issues, so maybe it would be better to use colons for separation (even on windows). I will add an issue to keep track this.

Thank you so much, now it works like a charm! I start with inet instead, that made my life much easier.
