Re: [sumo-user] Strange error of Omnet++/Veins/SUMO

Good news

By setting each C statement to comment, I get the reason of crash:

char *ret = strcat(cstr, new_str);

both cstr and new_str are two arrays of char.

The statement is available in line 76 of RSUControlApp as well as line 123 of VehicleControlApp. If I delete these lines, the simulation could run to the end.

However, I don't understand why Omnet++ crashes while only running instead of debugging.

Dear all,

From now on, I know how to build my own project for simulating traffic.

However, I get stuck on a new small problem.

The purpose of my project is very simple: every car periodically sends  messages to RSU and other cars. RSU replies immediately, other cars don't respond.

All messages are in TraCIDemo11pMessage format

The problem is that: my project crashes very quickly and as usual, Omnet++ IDE reports only "Finished with Error"  - no sense at all. Ironically, as debugging, the simulation could finish without any error

I could not identify the bug and how to fix it.

My project is located here: https://github.com/bkhnk48/tutorials

If you can't install my project, this video could help
