Author Topic: Unable to enter input when stepping line by line in the debugger? (Read 29099 times)

phoenixy · « **on:** February 25, 2013, 04:52:32 am »

Hi,

I most recently was using Code::Blocks 10.5 on Windows, and this worked fine. However, now it doesn't in Code::Blocks 12.11:

I am running a console app line-by-line in the debugger--I have a breakpoint set at the beginning of the function, then use F7 to progress line by line. However, when I get to a cin statement, I cannot actually input anything; the console window doesn't accept input, even once I am past the cin statement. If I use F7 again, the debugger seems to get stuck and the only way to exit it is to terminate the Code::Blocks process. Did this behavior change and is there something different I need to do in order to step line by line through a function? Thanks.

Does it still fail to work if you use c::b 10.05 or command line gdb, with your current compiler/debugger setup?
I think this should work fine, but I've not tried it on windows.
Can you post the full debugger's log?

phoenixy · « **Reply #2 on:** February 26, 2013, 05:58:38 am »

Thanks for the response! Yeah, it works OK in Code::Blocks 10.05 even with the same debugger and compiler versions. (Debugger is gdb 7.5, as you can see from the logs; compiler is minGW 4.7.1)

Here's my debugger log from Code::Blocks 12.11:

Here's the debugger log from Code::Blocks 10.05 (where it works):

And for reference, here's the code:

#include <iostream>
using namespace std;

double computeInterest (double base_val, double rate, int years)
{
   double final_multiplier;
   for ( int i = 0; i < years; i++ )
   {
      final_multiplier *= (1 + rate);
   }
   return base_val * final_multiplier;
}

int main ()
{
   double base_val;
   double rate;
   int years;
   cout << "Enter a base value: ";
   cin >> base_val; //this is line 20
   cout << "Enter an interest rate: ";
   cin >> rate;
   cout << "Enter the number of years to compound: ";
   cin >> years;

   cout << "After " << years << " you will have " << computeInterest( base_val, rate, years ) << " money" << endl;
}

Let me know if there's any other info I can provide!

@phoenixy
I don't have such issue. Can you enable the debugger-debug log, and paste the full log here. (Enable this by check on: Settings->Debugger->Commom->Full (debug) log)

Also, please use the Code/Quote Tags. (Do not directly paste log message)

phoenixy · « **Reply #4 on:** February 26, 2013, 05:41:15 pm »

Sure, here you go. These logs are from a different computer and project name than the logs above, but I can reproduce the problem on both:

oBFusCATed · « **Reply #5 on:** February 27, 2013, 01:01:14 am »

Hm, that bug again. I suppose you'll have to disable catching of exceptions in the settings of the debugger.

phoenixy · « **Reply #6 on:** February 27, 2013, 05:13:07 am »

Hmmm...I turned off the "Catch C++ Exceptions" checkbox in the debugger settings per your post and then restarted Code::Blocks but the problem didn't go away...any other ideas for steps I might try?

phoenixy · « **Reply #7 on:** February 27, 2013, 05:53:18 am »

Oh, hey, I just upgraded to gdb 7.5.1, and it works now!

jvmorren · « **Reply #8 on:** April 08, 2015, 04:11:41 pm »

I am having this problem too, but with Code::Blocks 13.12 Can someone please help me? I am using the same code as phoenix and am getting the same set of debugger messages.

oBFusCATed · « **Reply #9 on:** April 08, 2015, 09:02:59 pm »

Have you tried a recent night build? I think there was a fix for a similar issue.

And if it doesn't work post the full log from the debug session.

Ok, the log seems pretty awkward. Why on earth does a next gdb command behaves as though you've executed step command?

Can you try to start gdb from the command line and repeat most of the commands?
Also what are the gdb and gcc versions you're using?

jvmorren · « **Reply #12 on:** April 10, 2015, 03:16:21 am »

I've just had the weirdest thing happen to me. I opened up gdb in command line (via the folder under My PC) and basically did nothing except type in help. I then went back to Code::Blocks and it worked fine!! I seriously don't understand why! And because I never really needed any expert assistance, I would like to apologize for wasting your time, seriously. Thanks for the help.

Have you tried a recent night build? I think there was a fix for a similar issue.

And if it doesn't work post the full log from the debug session.

Also post cb version, os version, compiler and debugger version.
