Not an error. It just means that the objects / binaries
already are present : Nothing to be done.

Please open the directories in a file manager, and see for yourself.

i have added the missing pts_ pid and psn_ in struct_hdr in common/packet.h . and these error vanished..

can u help me read the output of this algorithm?

Can you attach the edited file common/packet.h as packet.h.txt ?

( The paper clip tool in the "Advanced Editor" is for attatcments.)

struct hdr_cmn {

Please use code tags http://www.linuxquestions.org/questi....php?do=bbcode

Code:

   459	struct hdr_cmn {
   460		enum dir_t { DOWN= -1, NONE= 0, UP= 1 };
   461		packet_t ptype_;	// packet type (see above)
   462		int	size_;		// simulated packet size
   463		int	uid_;		// unique id
   464		int	error_;		// error flag
   465		int     errbitcnt_;     // # of corrupted bits jahn
   466		int     fecsize_;
   467		int 	pid_;
   468		int 	psn_;
   469		int 	pts_;
   470		double	ts_;		// timestamp: for q-delay measurement
   471		int	iface_;		// receiving interface (label)
   472		dir_t	direction_;	// direction: 0=none, 1=up, -1=down
   473		// source routing 
   474	        char src_rt_valid;
   475		double ts_arr_; // Required by Marker of JOBS

I'm still getting a "pid error" :

Code:

sara/sara.cc: In member function `virtual void Sara::forwardData(Packet*, double)':
sara/sara.cc:2229: error: 'struct hdr_cmn' has no member named 'pid'

I have the same pb, but when I add this line in common/packet.h : inline int& pid() { return (pid_); }, the command make complete successfully. but I still have a pb when I try to run the script of sara run_sim.sh. this is the erreur:
./run_sim.sh: line 4: 2454 Erreur de segmentation ns manet.sara.FTP.tcl -rs 18

someone have an idea plz.
