OMNeT++ 5.5.1 debug mode not working in macOS.

[Minwoo Kim]

Hi, I want to use OMNeT++ for heterogeneous communication in VANET for my research.

Therefore, I was constructed simulation environment in my computer like below:

• OMNeT++ 5.5.1 (installed gdb from homebrew)
• Veins 5.0
• Veins_INET3 included with Veins 5.0
• INET Framework 3.6.6
• SimuLTE 1.1.0

For understand how it works OMNeT++, I was learning Tictoc example from Tutorial site.

When I was learning for debugging, it's some occurred problem. When I click the "Debug" button, the IDE does nothing. No error, no window appears, only the log "make: Nothing to be done for 'all'" is output.

What's the problem? I installed gdb and generated a certificate according to the installation guide.

I have also attached a photo for reference.

I had the same problem. I tried everything to enable debugging in my OMNet++ 5.5.1 on macOS Catalina but nothing worked. 

I was able to debug C++ code in Eclipse, but even with the same settings, OMNET++ 5.5.1 does not do debugging. 

Seems like a major problem with OMNeT++ 5.5.1 for debugging in macOS Catalina. 

I had to switch to another machine having Windows 10 because without debugging, it is almost impossible to work on OMNeT++.

Thanks very useful advice. 

So, in general, it's simulated using Ubuntu OS.

I think debugging is very important in development work. However, is debugging work essential in OMNeT++?

Yes, I believe with Ubuntu, the debugging should work fine just like in windows. 

Well, it depends on what you are going to implement in OMNeT++. 

When I was implementing a new routing protocol, debugging was much essential for me. 

But if you do not have to do extensive programming in OMNeT++, then debugging might not be much needed and you may use EV_INFO or print statements to check the values of variables (as an alternative to debugging).

Thanks very useful advice.

I have implement heterogeneous communication in VANET environment.

As you said, I'm trying to configure a simulation by building a new environment in Windows 10. It helped a lot.

Best Regards.

Sadly, gdb is pretty much unusable on macOS. LLDB is the way to go, however we found no fully usable LLDB backend for eclipse. OMNeT++ 6 (pre) bundles an lldb-mi executable which emulates *some* of the gdb command lines so that could be used as a drop-in replacement. OMNET 6 is configured to use that as a devugger. It's better than nothing, but it's still far from perfect.

I have written an article about this topic, which might be useful: https://docs.omnetpp.org/articles/omnetpp-debugging-tips/

Right now, I would try to use VS Code with the CodeLLDB extension and confure the simulation to invoke that debugger from inside the simulation. (i.e. not starting the debug session from Eclipse, but rather starting the debug executable and using the "Debug next event" menu item to drop into the VS Code debugger. It would broably work also win OMNeT5, however omnet 6 is better equipped for this...

I'm sorry for the late reply. Also thank you to useful advice.

I want to use OMNeT++ 5.6.2 or 6, but I have to use OMNeT++ 5.5.1 for add LTE interface in my VANET simulation. I haven't seen it in the installation guide, but can I use SimuLTE with OMNeT++ 6 (pre) as well?

Best Regards.

OMNeT 5.6.2 should work with INET 3.6.8 and SimuLTE 1.1.

OMNeT++ 6 preview 9 and SimuLTE 1.1 is not (yet) compatible. So you caanot use that combination right now, but updating SimuLTE should not be a big problem.

Thank you for useful information.

It's very helpful. :D
