    bad libraries or what?

    when I try to compile a DEV-C++ example or an allegro for DEV-C++ example the compiler says that the linker cant find the functions the program requires, but I have the allegro and the dev-c++ installed perfectly, so... why cant the linker find that functions??

    HELPEEEE!!!

    Are you including the libraries in your project? I do not know how to do it in dev-C++, but you need to do it to have them included in your program.

    Just remember that including the header file does not automatically include the actual library. You have to specify the libraries that you wish to link.

    For instance: if you are trying to link libwinmm.a, you would go to Compiler->Options, check-mark the box that says "include the following compiler commands" or something, and type:

    -lwinmm

    for libwsock32.a, you would type:

    -lwsock32

    ...and so on...
    Code:
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
    {
        return std::pow
        (
            std::complex<float>(std::exp(1.0)), 
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;
    }
