Code::Blocks debbuger failure - c++

Question

Before explaining my problem:
My OS is Ubuntu 12.04 LTS 32bits with 4GB RAM.
My IDE is Code::Blocks 12.11(I've had the same problem with 10.05)
I'm using the GNU GCC Compiler with the -g flag and the -std=c++0x flag.
When trying to debug this program:
using namespace std;
#include<iostream>
int main(){
int n=10;
for(int i=1;i<=n;i++){
int ax=i;
while(ax) ax--;
cout<<i;
}
return 0;
}
I can't get anything to happen,if I try the "Run to cursor" command or if I try to use breakpoints. They just get skipped and my program finishes running.
This is what I get in the debugger log:

If anyone wants to suggest a solution that implies using the terminal, please do it in the most noob-orieted terms you can find!
PS: How to add breaklines on stack-overflow when asking a question?(Solved-Thanks!)

Answer 1

Reading symbols from /home/classius/CodeBlocks/Dr/bin/Release/Dr...(no
debugging symbols found)...done.
This means you didn't have the -g option during compilation.
UPDATE:
file /home/classius/CodeBlocks/Dr/bin/Release/Dr
/home/classius/CodeBlocks/Dr/bin/Release/Dr: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.24, BuildID[sha1]=0x7da8c5cff4af5082d82eecc3ede59a5920b253a0, stripped
So it's 'stripped', which means -g option was not really used. You may recheck your compiler config or try to build the Debug version?

Answer 2

in settings menu choose debugger then gdb-cdb tab and then reset default
