How to debug

[Vic]

I am new to CodeBlocks, and try to work with the debugger an de following simple code.

Code

#include <iostream>
using namespace std;

int main()
{

    int q=100;
    int *p;
    char c;
    
    cout << "Hello world!" << endl;                                              //Breakpoint 1
    p= new (nothrow) int [q];
    if (p == 0)
    cout << "Error: memory could not be allocated";
    else {
    for (int i=0; i<q; i++)
        p[i]= i+1;

    for (int i=q-10; i<q; i++)
        cout << "P " << i << " = " << p[i] << endl;
    }
    delete [] p;
    cout << "Hello C++" << endl;                                                  //Breakpoint 2
    cin >> c;

    return 0;
}

When i press F8 (Start debugger) the debug windows show following

Do not use braces ( "(" and ")" ) in your path !

Thx for the replay.
I changed the path, but still have the same problem.

The output of the debug Window is now,

Which version of C::B, MinGW and which OS (and version) are you using ?

Did you read this : http://wiki.codeblocks.org/index.php?title=Debugging_with_Code::Blocks?
Turning on full commandline logging (and post the build log)  might also help to track down the problem: http://wiki.codeblocks.org/index.php?title=FAQ#Q:_How_do_I_troubleshoot_an_compiler_problem.3F

[Vic]

Changing the Compiler logging setting to full command line was the solution for the problem. But i have seen that when i set this back to the default setting the debugger function are still working. I can't not well understand this, but all right the functions are working that is the most important thing.

I still have a small question what is the difference between the debugger function Next Line and Next Instruction? And when i use the Next Instuction function automatic the disasemby window is opend is this normal or due to a setting?

PS. The version of codeblocks 8.02, OS = Windows XP and MinGW i don't no where do i find that. It is de version skip with the download of  Codeblocks 8.02


In every way thanks for the tips
Best Regards,

Vic

Next line - means goto next source (c/c++) line
Next instruction - goto next assembly/machine instruction

Ok thx for the info.
