Hi,

I have a problem running .cc in ns3 using nsc.

./waf ârun scratch/myreno

â Command ['/home/mir/ns-allinone-3.21/ns-3.21/build/scratch/myreno']
terminated with signal SIGSEGV. Run it under a debugger to get more
information (./waf --run <program> --command-template="gdb --args %s
<args>").

Waf works fine if the .cc doesn't need to use the nsc libraries.

A year ago I had ns3 in other machine, and I used nsc without problems. I
modified liblinux library and worked. But recently I installed ns3 in other
computer, and I try to use my old libraries, and this error appear.

./waf ârun scratch/myreno

â Command ['/home/mir/ns-allinone-3.21/ns-3.21/build/scratch/myreno']
terminated with signal SIGSEGV. Run it under a debugger to get more
information (./waf --run <program> --command-template="gdb --args %s
<args>").

With a debugger, insight, I got this

*>> *./waf --run mptcp --command-template="gdb-doc %s"

I don't know how to solve the problem. Can anyone help me? Thank you very
much.

PD: I had to make a minor change in my old .cc due to some changes in ns3
with times, and it works well without using the library from nsc.
