Eclipse/MinGW/CDT/GDB and problems with debugging

Question

I have some C++ code and try to debug it. main.cpp:

#include <iostream>
using namespace std;

int main() {
    graph<int> a;
    a.add(1);
    a.addEdge(1,2);
    std::vector<int> answ = a.getAdjacent(1);
    for (unsigned int i = 0; i < answ.size(); i++)
    std::cout<<answ[i]<<std::endl;
    return 0;
}

I have a breakpoint on "graph a;". But when I start debugging, I get:

The target endianness is set automatically (currently little endian)
No source file named C:\Users\home\workspace\graphcpp\main.cpp.

What's the problem?

Solution

This seems to be a relatively frequent reoccurring issue when using eclipse +cdt with gdb. Changing the default launcher from GDB (DSF) Create Process to Standard Create Process seems to solve the issue most of the time.

You can find this option under Preferences->Run/Debug->Launching->Default Launchers:

Also make sure you are compiling with -g debug info enabled.

I don't have a Standard Create Process; just the first displayed option, and Legacy Create Process.

standard was renamed to legacy. bugs.eclipse.org/bugs/show_bug.cgi?id=426586

Thanks that solved the issue for me, but I wander why Dsf does not function correctly

I have a project from Makefile with existing code and I have the same problem, but I can't find this menu option? Is it in the Makefile this setup or am I missing something?

@Elod Which version are you using and do you mean you cannot find 'Preferences'

[Elod]

I'm using Eclipse Version: 3.8.1 and the Run/Debug Settings has no drop-down option (only one window, with my launch configurations). The debugging stops at a line: if (this->nextState != NULL) delete this->nextState;. No error massage and if I execute if step, than application stops: The target endianness is set automatically (currently little endian) <terminated, exit value: 0>gdb

@Elod Perhaps give Luna SR2 release a try -- it comes packaged with CDT 8.6.0. I just checked it out and the setup is the same except its renamed to Legacy Create Process as tzafrir pointed out. Make sure you have [Debug] selected in the 'Launch Type/Mode' otherwise 'Preferred Launcher' will be empty.
