Hi,

After compiling new kernel stack in net-next-nuse to use MPTCP in ns-3-dce, getting error.

linuxdce@neha-Inspiron-N5010:~/bake/dce/source/ns-3-dce$ sudo ./waf --run "dce-iperf-mptcp" --command-template="gdb %s"

Hi,

Thanks for the view, I was able to map finally the correct liblinux.so -> libsim-linux-4.1.0.so file and not liblinux-4.1.0.so which gets created in the net-next-nuse-4.4.0 directory.

This can be closed now.

regards
