Installation problem

[Jyoti Agrawal]

Hi,

I am trying to install DDD  < ddd-3.2.1> in Linux 7.0. I used 
$./configure
$make 
I got the following messages(Message 1), what should I do now?


Message 1
---------
cc1plus: warning: -fexternal-templates is deprecated.
cc1plus: warning: Please see the documentation for details.
In file included from ddd.C:184:
AgentM.h: In method `AgentManager::AgentManager (void (*) (...))':

argument `2' to `signal (int, void (*) (int))'

argument `2' to `signal (int, void (*) (int))'
make[1]: *** [ddd.o] Error 1
make: *** [all] Error 1

------------------------------------------
It seems that the DDD has installed because when I type 
$ddd

it gives 

ddd: error while loading shared libraries: libXm.so.1: cannot open shared
object file: No such file or directory

I would be highly grateful to you for this help. I  used this software
to debugg  my code but, now I don't have access to it. 

Thanks in advance,

Jyoti
