DEBUGGING problem

[Skeezix]

my problem is this i followed the instruction on the wiki about debugging and watching a variable but thew problem is my debugger is way to fast...i think its not even using the breakpoints i assigned,it just stopped to get input then zoom its over already..can you help me on this..maybe a step by step process on how to use the debbugger...also is there a way to step line per line in the debugger?

thanks

See the section on debugging a program.

ive already tried that article...the problem is when i click on 'run to cursor' the other option for debugging cant be click any more also it doesnt do what the article said it would do...

[Skeezix]

here is my code:

Code Select Expand


#include <iostream>
#include <iomanip>

using namespace std;

void Seive( int test, int *ar, int bound );

int main()
{
   int x=5;
   cout<<x;
   cout << "Input the largest number to get the primes:" << endl;
   int limit = 0;
   cin >> limit;
   int bound = limit + 1;
   int array[bound];
   for ( int i = 0;i < bound;++i )
   {
      array[i] = 1;
   }
   array[0] = array[1] = 0;
   Seive( 2, array, bound );
   Seive( 3, array, bound );
   Seive( 5, array, bound );
   Seive( 7, array, bound );

   cout << "PRIME NUMBERS" << endl;
   int p = 0 ;
   for ( int i = 0; i < bound;++i )
   {
      if ( array[i] != 0 )
      {
         cout << setw( 5 ) << i << " ";
         ++p;
         if ( !( p % 4 ) )
         {
            cout << endl;
         }
      }
   }

   return 0;
}

void Seive( int test, int *ar, int bound )
{
   int mod = 0;
   for ( int i = 0;i < bound;++i )
   {
      mod = i % test;
      if ( mod == 0 && i != test )
      {
         ar[i] = 0;
      }
   }
}


here is the output when i used 'runto cursor'

Hi,

Do you have the Build target set as Debug?

I just ran your code, and it worked exactly as described in the manual. I was able to run to cursor, run to breakpoints, step in, etc. and use the watch window.

De debugger is so kind to tell you several times what your probelm is. Please enable debugging symbols for compilation (and probably linking, depending on your compiler suite). Keep in mind that you have to do a re-build for the changes to take effect.

i followed the instruction STEP BY STEP so yes i check the generate debbuging symbols..or something like that

Make sure that (in addition) you *don't* have stripping symbols (-s) and any optimisation enabled(-O1... -On). Otherwise please post a minimal example project here for us to try.

I tried his code that he gave above and the debugger worked perfectly. I wonder if he is using a project or just compiling and trying to debug the .cpp file alone.

I tried your project, worked perfectly (on OpenSuse 10.2).
Your project file looks OK, so those settings are ok.


Could you post the full building log.
To see this do : Settings->Compiler & Debugger->tab "Other"->Compiler logging="Full command line"

and then do rebuild all and paste the build log.

You are stripping the debug symbols from your executable when you are linking (as MortenMacFly menitoned, see the '-s' above).

how do i turn it off...i already did the Project->Build Options->Compiler settings thing
