No code visualization

[Mauro Fiorentino]

Hi ,

I have got a problem with the DDD debugger on a linux machine.
I compiled with the -g option and when I run the ddd I can see just the 
first 4 lines (commented) of the code I want to inspect.
If I try to open the the code from the menu I receive the following 
message :
" Line 1 of Fitlines.C is it at address 0x804b8c4 but contains no code"

The very same code with the same Makefile works great on Unix machine.

Do you have any suggestions  ? What shall I check ?
Attached is the log file from DDD.

Thanks, Mauro
