SIGSEGV error without a solution as yet

[André Gama]

I worked for a long time to fix this error code, but it still fails. Can anyone help me with this? I already checked the wiki, but without success.

Code link: https://www.friendpaste.com/58N9PYKS6f6PlUbmXKoIb5

Errors:

Starting program: /home/andre/repos/ns-3-allinone/ns-3-dev/build/scratch/pm-ex21r 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".

Program received signal SIGSEGV, Segmentation fault.
0x0225845c in std::vector<ns3::Ptr<ns3::Application>, std::allocator<ns3::Ptr<ns3::Application> > >::size (this=0x28)

571          { return size_type(this->_M_impl._M_finish - this->_M_impl._M_start); }

Can you help me? 

Thank you all.

Hi Andre,

From the wiki page I answered you before, you could get information why you receive this error. Or you can look at the GDB tutorial online to get more info about using it.

So after you run the program in the debug mode, and you get the error, you run the command "backtrace" (or "bt" is the same) to see where this problem originated. For example:

0x000000010409c714 in std::vector<ns3::Ptr<ns3::Application>, std::allocator<ns3::Ptr<ns3::Application> > >::size (this=0x40) at stl_vector.h:400

400      { return size_type(this->_M_impl._M_finish - this->_M_impl._M_start); }

(gdb) bt

#0  0x000000010409c714 in std::vector<ns3::Ptr<ns3::Application>, std::allocator<ns3::Ptr<ns3::Application> > >::size (this=0x40) at stl_vector.h:400

#1  0x0000000103f3dcf1 in ns3::Node::AddApplication (this=0x0, application=@0x7fff5fbfd4a0) at node.cc:144

#2  0x000000010211021b in ns3::OnOffHelper::InstallPriv (this=0x7fff5fbfd758, node=@0x7fff5fbfd520) at on-off-helper.cc:74

#3  0x00000001021106c9 in ns3::OnOffHelper::Install (this=0x7fff5fbfd758, node=@0x7fff5fbfe828) at on-off-helper.cc:48

#4  0x0000000100009db9 in main (argc=2, argv=0x7fff5fbffa20) at andre.cc:197

So if you go to line 197 in your code (at least the copy I made) you will see where it all starts. It's a problem with the install of an application.

You have 5 wifi nodes (  uint32_t nWifi = 5; ) and you install the application on the node 8th ( ApplicationContainer apps = onoff.Install(wifiStaNodes.Get(7)); ) 

Regards,

K.

Hi.

Thank you, Konstantinos.

I'll check this and then report the result. Thank you very much.

Regards.
