[ns] reg : Linking errors
Hai Everybody,
For linking the c++ code with otcl
script, I have included the C++ code and it's object file under the ns2
directory and used make command to re-compile it for the changes
included. But it is producing the following errors ... So, Kindly
suggest me some guidelines regarding this

[ns] regarding packet header files
Hai...
I have created a new packet header for my project
regarding geographic routing protocol for adhoc networks. with this
mail i have included my header file.
#ifndef __bsr_h__
#define __bsr_h__
#include agent.h
#define NETWORK_DIAMETER 8 // 8 hops
// The followings are used for the forward() function.
#define DELAY 1.0
#define NO_DELAY -1.0
#define ARP_DELAY 0.01
class BsrAgent : public Agent {
public:
int command(int argc, const char*const* argv);
void greedy(int
src);
void readmatrix();
void findangle(double src,double next,double dest);
void display(int src);
};
#endif /* __bsr_h__ */
but while compilation it produces the following errors.
bsr.h:5:19: error: agent.h: No such file or directory
