Re: Detaching after fork from child process

[Anurag Goyal]

I tried the simple program and it run perfectly fine with no such message, as shown below, But I want to debug a very large application which uses a managed make thruout the project and when I run that thru gdb it gives me messages "Detaching after fork from child process XXXXX" and it stops sometimes and asks to press the enter key to continue or q to quit. is there anything wrong with my configuration...?

cat 1.cpp
#include<iostream>
using namespace std;
int main()
{
        cout<<"The simple program"<<endl;
        return 1;
}

Sounds abnormal - try very simple code, as in this link:
http://sources.redhat.com/ml/gdb/2006-02/msg00069.html
and then followup to the gdb group with more details, such as what OS
you are using, which gcc and include a sample of code which produces the
problem on your machine that others can compile/execute.
