I must use ddd!!Please help me!

[franca . d]

Hi!
I've a problem with ddd: I compiled my C++ program (my.cc) with -g -o 
options like specified in the manual: 
  g++ -c my.cc
   g++ -g -o my my.o
Then I try to exec the command "ddd my" and the ddd's interface started 
but Ireceived the message: " /home/franca/...../init.c:No such file or 
directory".
So I tried to change gdb settings by the menu edit (like help suggests) 
and I found a wrong directory in the Search path for object 
files:/home/franca/bin.
At the end I was so hopeless that I uninstalled ddd3.3.1 from redhat
(7.2) and then I installed it again. The first time that I wrote the 
command "ddd my" the program started successfully and I degug my 
program but after I have had the same problems.
I hope you can help me as soon as possible.
Thanks in advance

Bye 
Franca
