I posted this topic a few days ago but still haven't found a solution =
yet. However, I believe I'm able to provide more information now. Here =
is a log showing what I'm up against:
vitoc# pwd
/usr/temp/cpp
vitoc# ls
test.cpp
vitoc# cat test.cpp
#include <iostream>
using namespace std;
int main()
{
cout << "Hello world!";
return 0;
}
vitoc# g++ -g -o test test.cpp
vitoc# ls
test test.cpp
vitoc# gdb test
