Problem with debugging
Piotrek_16:
Hi.
I want to debug this part of code and i have problem with it.

When I try to debug and press F7 few times, debugger stops.
Here you have debugger logs:

If I try to stop debbuger (Shift-F8) I obtain message: Trying to pause the running process...
And It doesn't stop!
There is not a problem with integer value or even with float. There is a problem with double, long e.g.
Please help.
I have C::B 12.11 with minGW
oBFusCATed:
1. enable full logging (see settings -> debugger),
2. then try to debug again
3. then copy-paste the full log using code tags (use the '#' button in the new post interface of the forum)
Have you used the callstack/backtrace window?
Probably gdb is executing step-into instead of next-line, because either you have optimizations enabled or some inlining has happened.

I used only Watches window.
I have this from Callstack window: std::ostream& std::ostream::_M_insert<double>(double) () (??:??)
I don't know what is backtrace window?!
I've installed C::B on my PC yesterday and I was trying to test this IDE and I obtained this problem.
oBFusCATed:
Do you have optimizations enabled in your target options?
For me this is a problem of gdb/mingw you have installed, not in C::B.
Can you try to use gdb from the command line to see if the problem happens there, too?

As I mentioned I'm newbie :) Can you tell me what exactly I have to do? I didn't change anything except c++11 option, I set it on in project -> build options.
Where can I find target options?
From the command line I used command
--- Code: ---c++ main.cpp -o file
--- End code ---
I obtain executable file which worked.
