Got error when add a new antenna module into NS2!

Hi,

I write a new antenna module and want to add it into NS2. I can compile it successfully, but when I run the simulation file, I got the following error. It seems ns2 does not identify the new module. Could someone give me a help? THX a lot.

Code:

num_nodes is set 4

? May be you are using the original 'ns' ?

The new "ns Antenna/DirectionalAntenna" binary must be used
for "Antenna/DirectionalAntenna"

Original 'ns'? What does that mean? How can I choose new or old?

Say you have set your PATH to "another 'ns' ".
Then that ns will be used.

The new " 'ns' Antenna/DirectionalAntenna" binary can be copied
to /usr/local/bin/ . Then it is in a system PATH.

To be absolutely sure, it is used, please try :
'/usr/local/bin/ns <simulation file>.tcl'

.

I only have one NS version in the system, so I am not sure it is the problem of PATH. I will try it. Thank you anyway.
