Unable to run simulations as root.

[Thecave3]

To run the simulations campaign as root with the new toolchain a flag (--enable-sudo) should be included in the command and at the moment there is no way to do it in sem.

I propose to add this flag in the CampaignManager or to check this at runtime before launching the ./ns3 configure command.

What do you think @pagmatt and others interested?

In my opinion the best approach is to modify the SimulationRunner init function:

sem/sem/runner.py

Line 26 in da63bc5

def __init__(self, path, script, optimized=True, skip_configuration=False,

to take yet another parameter (enable_sudo, which defaults to False), and reflect these changes in the configure_and_build function by including the same parameter:

sem/sem/runner.py

Line 135 in da63bc5

def configure_and_build(self, show_progress=True, optimized=True,

and, finally, conditionally append the corresponding configuration flag (--enable-sudo) to the configuration command.

By the way, in the meantime you should be able to run simulations using SEM by manually configuring ns-3 with the --enable-sudo command, and then by setting SEM's skip_configuration flag to True to prevent SEM from overwriting the manual configuration.
