Does the program run for 1 second then quit? There's really not enough
information here to help you. I suggest you use a simple program with a loop
to see if you have the compilation settings right. Something like:
int
main()
{
for (int i; i < 1000000; i++;) {
std::cout << i;
}
}
You might need to adjust the count so that it runs for awhile. Then you can
move up to boost stuff...
HTH,
