Comment 1 Manuel Requena 2018-07-12 17:10:49 UTC

Please, could you send the simulation program to reproduce the problem?

Comment 2 Jiantao Fu 2018-07-12 17:16:09 UTC

thanks, upload to https://github.com/fuji246/ns3-rmcat/tree/lte.

run "./test.py -s rmcat-lte -w rmcat.html -r"

Comment 3 Manuel Requena 2018-07-12 17:53:01 UTC

Please, could you describe your full system? OS, compiler version, ns-3 version...

This module does not compile in a Ubuntu 16.04 (64 bit) with g++-5.4.0.

Comment 4 Jiantao Fu 2018-07-12 22:28:54 UTC

Sorry, I'm using MAC. I have fixed the compile issue in ubuntu 16.04 gcc 5.4.0, you can pull the latest code https://github.com/fuji246/ns3-rmcat/tree/lte.

Comment 5 Manuel Requena 2018-07-14 04:23:24 UTC

Please, review your code.
The problem is in how you build the lte network. The LteHelper is a local variable in a method (LteTop::Build). So, when the method is finished, the helper is destroyed and some objects it creates too.

Comment 6 Jiantao Fu 2018-07-16 10:45:35 UTC

I've changed the code, still crashes.

Comment 7 Jiantao Fu 2018-07-17 16:44:00 UTC

Comment 8 Jiantao Fu 2018-07-18 14:10:26 UTC

Remove the following lines works, but I need those for debugging.

    lteHelper->EnablePhyTraces ();
    lteHelper->EnableMacTraces ();
    lteHelper->EnableRlcTraces ();
    lteHelper->EnablePdcpTraces ();

Comment 9 Manuel Requena 2018-07-24 06:28:17 UTC

(In reply to Jiantao Fu from comment #6)
> I've changed the code, still crashes.

I've check your code and you added the global variable for the lteHelper. But you kept the local variable with the same name.

Please, review your code again. And review the concepts of global variable, local variable and scope of local and global variables when you define both with the same name.

Comment 10 Manuel Requena 2018-08-02 04:30:16 UTC

Hi Jiantao,
Do you have any update on this?
If not, we should close the issue.

Comment 11 Jiantao Fu 2018-08-22 18:33:22 UTC

sorry, my bad, it's working now. Thanks so much!
