Depending on how much language support you want, you may want to compile without the D runtime (in which case you only have access to the C standard library, and various features are disabled, such as classes/interfaces, garbage collection, exceptions, and most of the D standard library). You can disable the D runtime in GDC with -fno-druntime and in LDC with -betterC. With those flags, the basic hello world program looks like this:

    import core.stdc.stdio;
    extern (C) void main() {
        printf("Hello world\n");
    }
