Problem with debug

My program is working, neither bugs nor problems, but instead of printing in the screen all the datas I would like to control I prefer to run debug with a run to cursor and watch step by step the evolution.
That's what I was used to do using VC++ few years ago.
But it seems that it doesn't work. Maybe I need to select other settings but I don't know where or how.

I think what Pecan ment was: If you change the settings according to Pecan's post, you will get a better log file. If you post this log file, Pecan can assist you better :).

Set:
//-- Full Compile Logging --
"Settings" -> "Compiler and Debugger"
"Global Compiler Setting"
"Other Settings"
"compiler logging:" set to "Full Command Line"
Paste the compiler output here, and paste the minimal program source with step by step instructions on how to re-create the problem.

Well, I did exactly what you told me.
A simple console project "hello world", and the run to cursor works. But I noticed that the output screen didn't appear.
So in my other project, because I have to enter many data, code blocks crash because with no output screen of course I can't enter them and it stays pending waiting for them, and even while trying the stop debugger it doesn't work, I have to force quit codeblocks...
PS : What do you mean by complier output? i.e. which one of the tabs?
gd_on:
Do you use Win2000 (or a previous one) ?
if yes, it's normal, because since 11th march version, debugger.dll has been changed (see http://forums.codeblocks.org/index.php/topic,5391.msg41849.html#msg41849 and the following posts) and debug does not work properly. So try the previous nightly (9 march).
if not, try also the previous nightly.
In any case, it's nice to indicate also your OS version, gcc version, ....

Pecan:
If it's a Linux console you need, here is a patch to provide one:

Yes I'm currently working on Linux.
I still didn't try on Window (XP SP2 version) because I don't have my laptop now.
Now the question is how to apply this patch :? Never did it before...
