SIGBUS everytime

[mida...@gmail.com]

Yesterday ns-3 stopped working. Now I ALWAYS get a SIGBUS error.
 

Waf: Leaving directory `/home/minako/repos/ns-3-allinone/ns-3-dev/build'
Build commands will be stored in build/compile_commands.json
'build' finished successfully (3.933s)
Command ['/home/minako/repos/ns-3-allinone/ns-3-dev/build/scratch/object-names'] terminated with signal SIGBUS. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

I tried debugging it, but I always get a "Sorry, the application gdb has closed unexpectly" windows. I tried running one of the ns-3 examples, but I still get it. I tried running a one line simulation, but nothing changed. What can I do?

Hi,

SIGBUS error explained here http://www.linuxprogrammingblog.com/all-about-linux-signals?page=4

"The SIGBUS signal is sent to the process when you access mapped memory (with mmap(2)) that doesn't correspond to a file. A common example is that the file you've mapped was later truncated (possible by another program) and you read past it's current end."

Without further information on your system, ns-3 release etc, we can not help.

Have you tried to clean and re-build ns-3? Have you modified anything in ns-3?

Regards,

K
