I'm trying to get LLVM CLANG working with Code::Blocks.

I've got basic compilation working, now I'm trying to get debugging working.

So I set up a test project called "TestConsoleDebugger", which has the following code
Quote
#include <iostream>
#include <cstdio>

int main()
{
    int iterations = 0;
    FILE* fp;

    while (iterations < 1000000)
    {
      iterations++;
    }

    fp = fopen("Debug.txt", "a+");
    fprintf(fp, "Iterations = %i\n", iterations);
    fflush(fp);
    fclose(fp);
    return 0;
}

and breakpoints on "iteration++;" and "fp = fopen("Debug.txt", "a+");

When I click the red "Debug / Continue" arrow, I get

Code::Blocks does not stop at any breakpoints, the console does not appear, and notably, "Debug.txt" does not appear.  When I click the green "Run" arrow, in contrast, it pops up the console and "Debug.txt" appears in the project directory.

Is there any advice for how to get lldb to actually debug from Code::Blocks?  E.g., do I need to put anything in for "Debugger initialization commands" in the debugger setting?

This means the debugger found an error and quit without executing your program at all. C::B expects GDB or CDB as debugger, not LLDB, and it uses commands specific for them that LLDB does not understand. Also, it parses answers using regex that will fail with LLDB.
