Hi everyone,

I have a serious problem right now, my DDD wont work anymore.
When i launch it : bash$ ddd
I cant do anything, the little green thing at the right bottom constantly blink and it says Opening session "2327865q4a1...3243465464" at bottom left
I cant open program, the window just doesnt show
the debug window says :
Could not attach to process. if your uid .. bla bla.. or try again as the root user.
ptrace: Operation not permitted
/home/.../"random 4 digit": No such file or directory

When i try to run it as super user : bash$ sudo ddd
its the exact same thing except that i dont have opening session at bottom left.
And the debug consol says a bunch of Reading Symbol for .. Loaded Symbol for..

but still can't debug :/

I hope you guys can help me on this.

Please indicate exactly how you are compiling your application, and then specify exactly how you are running DDD. If the error still persists, please post the exact error.

Right now I suspect that because your executable file has white-space in the file name, you are not properly escaping these with a backslash. For example:

Actually Im executing ddd without arguments, i just type ddd in my terminal.

/home/.../"random 4 digit": No such file or directory

And this has nothing to do with any executable.
I type "random 4 digits" because it varies through ddd execution it can be for example /home/.../3452 or /home/.../2145

Edit : its the exact same problem when i run : ddd test ( test is an executable )

Wait... you enter 'ddd' in a terminal, press <enter>, and then you see "/home/.../"random 4 digit": No such file or directory??

Yes
In the DDD: Debug Window

Is 'ddd' aliased to something?

Try entering /usr/bin/ddd

I have the same problem :/

Edit : btw im on ubuntu 12.04, and i did a purge of ddd and gdb then reinstalled both. and gdb works well.

Do you have a file ~/.gdbinit?? If in doubt, try running ddd again, but specify the -n option. For example:

No i dont have a .gdbinit in my homedirectory. ddd -n does the exact same thing :/
edit : the 4 random digits seems to be the pid of the ddd processus

I get the impression that the "random 4 digits" is actually a process ID. Could you verify the permissions on /proc
It should be something like:

i get : dr-xr-xr-x 185 root root 0 juil. 2 2012 /proc

Well, I really do not know what the issue could be.

Check to see if you have a hidden directory ~/.ddd. If so, remove it, and then try launching ddd again.
