    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:
    int main(void){srand(time(0));for(double l=rand(),l0=0,l00=0;;l0+=0.1){for(double l000=0;l000
    <1;l000+=.001,l+=((double)rand()/RAND_MAX)/0x64,l00+=((sin(l*0x8*atan(l0)*l000-(l0*0x8*atan
    (l)))*0.5)+0.5)){l00-=floor(l00);for(size_t l0000=0,l00000=(size_t)(0x50*(l00));l0000<l00000;++l0000
    )putchar(0x20);putchar(0x61+(int)((double)rand()/RAND_MAX*0x1a));putchar('\n');}}return 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
