Hi guys,
I used OMNeT++4.6 in ubuntu, and found that breakpoints are unavailiable when debugging. However, I can set the debugger with "stop on startup at main" and it works.
How can I debug in ubuntu with IDE. As I know, it works in windows. Thanks!

Debugging works under both Windows and Linux.
Under Ubuntu, you probably need to install the nemiver package and enable the debugging of non-root processes.
Both steps are described in the OMNeT installation manual.
Older versions of OMNeT and GDB also sometimes had the problem that breakpoints set during a debug session were ignored. Restarting the simulation in debug mode with the breakpoints already set was a workaround for this.

Thank you Michael.

I have already installed nemiver (but I don't know how to configure nemiver in OMNeT++'s IDE), and "kernel.yama.ptrace_scope" was set as 0. Is any other configuration needed? In the install guide pdf, how to do for " you want to be able to use OMNeT++ just-in-time debugging
(debugger-attach-on-startup and debugger-attach-on-error configuration
options)."
I'm new to OMNeT++ and eclipse. Thanks!

No nothing else, the kernel ptrace will work after a restart.
Did you try to set your breakpoints and then start the debugging session?

Yes. But breakpoints are ignored after the debug starts. Operation like "Run to line" is unavailable too. Is it this a bug? or debugging with GUI is not supported in linux? What i use are Ubuntu16.04 and OMNet++4.6.

No debugging is supported under Linux too, just like I wrote.
Older OMNET versions (prior to v5.1) had an issue with the setting of breakpoints during a debug session, again like I already wrote (https://dev.omnetpp.org/bugs/view.php?id=956).
Either switch to a newer version of OMNeT or set your breakpoints before you start your debug session. "Run to line" is probably not working due to the issue that breakpoints during a running session are ignored.

I found that, in OMNet++ 4.6 in ubuntu, the debugging can work if I set the breakpoint during the debugging is running. In other words, do not set breakpoints before you press the debug button, otherwise, the breakpoints will be ignored.
