I have been trying to get NTP installation working with DCE and had no luck so far. Here is what I have done so far:

NTP installation:

export CFLAGS="$CFLAGS -fPIC"
export CXXFLAGS="$CXXFLAGS -fPIC"
CXXFLAGS="$CXXFLAGS -fPIC" CFLAGS=-pie CFLAGS=-rdynamic ./configure --enable-linuxcaps
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:"/usr/include/x86_64-linux-gnu/sys" CFLAGS+=-fPIC CFLAGS+=" -U_FORTIFY_SOURCE" CFLAGS+=" -D_FORTIFY_SOURCE=0" CFLAGS+=" -g" LDFLAGS=-pie LDFLAGS+=" -rdynamic" LDLIBS="-llapack -llapcke" make
make install

DCE CODE:

I just modified the given example "dce_iperf.cc" to make the following changes on Node 0. The rest of the file looks as such excepting for these new additions:

dce.SetBinary("ntpd");

dce.ResetArguments ();

dce.ResetEnvironment ();

dce.AddArgument ("-c");

dce.AddArgument ("/etc/ntp.conf");

dce.AddArgument ("-p");

dce.AddArgument ("/var/run/ntpd.pid");

dce.AddArgument ("-g");

dce.AddArgument ("-u");

dce.AddArgument ("104:110");

apps = dce.Install (nodes.Get (0));

apps.Start (Seconds (0.7));

ERROR in waf:

I made the following additions to "model/libc-ns3.h" to get rid of my previous errors:

NATIVE (log10)

NATIVE (frexp)

NATIVE (setsid)

But I am stuck at the following error and I am not able to find a resolution even if I set the "LD_LIBRARY_PATH" correctly.
