about ns3

Code:
Command ['/home/student/ns-allinone-3.10/ns-3.10/build/debug/examples/wimax/wimax-simplebs'] terminated with signal SIGSEGV. Run it under a debugger to get more information (./waf --run <program> --command-template="gdb --args %s <args>").

while running our own program in ns3 we got the above error...
what does this error mean??

It crashed.

Segmentation fault means it tried to access memory addresses that either didn't exist, or the program didn't have permissions to access in that manner. Unfortunately, just "SEGMENTATION FAULT" tells you little about why. It doesn't even tell you where. The OS doesn't care about such things, it just kills things which don't obey them.

It was an unusually helpful error though, in that it told you how to get better information on the segfault.

Don't think this really belongs in 'networking', more of a programming problem.
