    Question library missing?

    When linking an application, I get a message "undefined reference to _WinMain"
    Apparently I'm missing including a library, anyone know which one I need to link with?

    Yes, you are missing a library if you get that error. WinMain? You need to do this:
    #include <windows.h>

    Are you doing windows programming? If so, you really should have posted this in the Windows board. That's what you use WinMain for, I'm sure you know.

    yes, I used the #include <windows.h> and still get the error.
    yes, I'm doing windows programming with C. Should I still use the
    windows forum?

    Depending on your compiler, you must manually set the "compile for Win32" mode.

    In Bloodshed Dev it's Options->Compiler Options->Linker-
    ->"Compile For Win32".

    Your's may have some similar mechanism.
    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;
    }

    Yes, what compiler are you using? I think there are some settings for that sort of thing.

    Thumbs up

    Just needed to add the
    int WINAPI WINMAIN() API function to the program source.
    Still get a warning, but also now I get an exe.
    Thanks
