[ns] recompile problem

[Rania Kamal]

hi all 
 
when i recompile ns2 to reflect changes that i made in ns2 files by typing make in ns2 directory appear to me the following:
 
Makefile:468: warning: overriding commands for target 'gen/'
Makefile:465: warning: ignoring old commands for target 'gen/'
Makefile:472: warning: overriding commands for target 'gen/'
Makefile:468: warning: ignoring old commands for target 'gen/'
make: *** No rule to make target 'int.Vec.o' , needed by 'ns' . stop.
 
thanks
