Something strange happens: I didn't modify any part of my ns3 c++ code, and running a compilation this is the error that appear:
[ 815/1681] cxx: scratch/initial-scenario.cc -> build/scratch/initial-scenario.cc.1.o

I don't understand why this error come out. The strange thing is that I'm working with two similar codes in two different directories and the error appear in both but I didn't modify anything. Could be a problem of the compiler? Any suggestion?
I solve the problem following what is suggested in here: https://www.nsnam.org/wiki/Ns-3.24-errata
The problem is related to the update of Xcode 7.0
