Runtime error on run_example

[khevessy]

Hello,

I built without any error. Now I have the same problem as in #52: when I try to run cmake --build build --target run_example, I get the following error:

A runtime error occurred:

Class "VeinsConnectionManager" 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() -- in module
(omnetpp::cModule) World (id=1), during network setup

Launch a debugger with the following command?

nemiver --attach=46371 &

I tried recompiling but with no success. I also tried reinstalling python3.

My setup: Linux Mint 20 (Ubuntu 20.04). Omnet++ 5.7 cmake 3.16.3 make 4.2.1 gcc 9.3.0 boost 1.71.0

Do you have any idea what could I be doing wrong?

Regards, Karel

Hi Karel,

are there any further (error) messages printed before "A runtime error occurred"?

Hi Raphael,

no, there are not any errors before. After I press Just break in that error window, make stack trace is shown in a command line:

Trace/breakpoint trap (core dumped)
make[3]: *** [scenarios/artery/CMakeFiles/run_example.dir/build.make:57: scenarios/artery/CMakeFiles/run_example] Error 133
make[2]: *** [CMakeFiles/Makefile2:1380: scenarios/artery/CMakeFiles/run_example.dir/all] Error 2
make[1]: *** [CMakeFiles/Makefile2:1387: scenarios/artery/CMakeFiles/run_example.dir/rule] Error 2
make: *** [Makefile:513: run_example] Error 2

By the way, what I want to accomplish in the end is running your Vanetza stack on a V2X device and then decide if I will be writing my own implementation of C-ITS protocols. So running Artery in a Linux PC is just a preparatory step for me to get started with this and if it is not possible to run this example for me, it is not such a big deal.

I have just installed OMNeT++ 5.7 to check if this triggers some errors on my machine. However, everything builds and runs smoothly here. The versions of your listed packages look also fine to me.

Can you please directly invoke make run_example in your build directory? I think cmake may hide some output.

Hm, that is strange. Do you see an output line with -- Enable Veins integration when you invoke cmake . in your build directory? You should see several such feature integration lines in the form of --Enable \<feature> integration along with Veins.

[khevessy]

Yes, I can see that, whole output for cmake . is:

Do you think that the problem might be caused by the fact that I have installed Omnet++ without Akaroa, is it needed?

[khevessy]

Hello Raphael,

I tried the build process again on freshly installed Linux Mint and it can now be run okay. I do not know what was wrong, on the old system the problem persists. I think we can now close the issue. Thank you for your kind help.
