Segmentation fault in model/ns3-socket-fd-factory.cc

[Hans van den Bogert]

After continuing with DCE using another binary, compared to my other recent thread, I encountered this segmentation fault:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0x7ffff7fba700 (LWP 13038)]
0x00007ffff7b1b3d0 in ns3::Ns3SocketFdFactory::CreateSocket (this=0x642040, domain=2, type=2, protocol=0) at ../model/ns3-socket-fd-factory.cc:82

The executable is doing some udp sendto, so nothing too fancy

I’m not sure if I’m doing things wrong or this is a bug in DCE, if it is the latter and source for the executable is needed let me know.

I guess the error is different from another one.

The crash is because of failing to obtain the socket factory
name of ns-3.

TypeId tid = TypeId::LookupByName ("ns3::UdpSocketFactory");

It's out of my imagine but wondering how did you build DCE
(and ns-3) ? bake ?

or missing ns-3 module dependency in wscript for your
example ?

I'd like to see at least:

- wscript
- your ns-3 script
- source of executable running on DCE, and Makefile (how to build it)

thanks !

Solved, same reason as https://groups.google.com/d/msg/ns-3-users/2Y5FzSph7Lk/rc6tWDn6SDMJ

I didn't install a internetstack in the node.
