loading a compiled shared library in otcl: Ex_Init not found

Hi ns-users,

I am trying to find a way to integrate my module into ns-2.35 without 
modifying the ns2 headers, Makefiles, tcl files etc.

I have compiled a sample code, "ex-linkage.cc" to a loadable shared 
library "ex-linkage.so". The code and the Makefile to build it can be 
found here: https://github.com/chudur-budur/mdp-wsn/tree/master/ex-linkage

I am loading this .so object in the tcl script (ex-linkage.tcl file in 
the link above) by calling "load ex-linkage.so" and then calling the ns 
like this --

user@pc:~$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:. ns ex-linkage.tcl

however the otclsh (i.e. ns) says --

couldn't find procedure Ex_Init
     while executing
"load ex-linkage.so"
     (file "ex-linkage.tcl" line 3)

Is there any work around for this ? What is "Ex_Init" and how do I write 
it ?

thanks in advance.

khaled
