Getting undefined reference to __real_main, when linking hello world.

Hello! Something must be off with the generated linking order.

#include <hpx/hpx_main.hpp>
#include <hpx/include/iostreams.hpp>

int main()
{
    // Say hello to the world!
    hpx::cout << "Hello World!\n" << hpx::flush;
    return 0;
}
