D book的例子不起作用，奇怪的错误

全部，

我正在使用Xamarin Studio 4.08和Mono-D使用DMD2编译器对D进行编程。当我尝试编译以下内容时（来自The D Programming Language - Alexandrescu，2010-第10页）：

import std.array;
bool binarySearch(T)(T[] input, T value)
{
    while (!input.empty)
    {
        auto i = input.length / 2;
        auto mid = input[i];
        if(mid > value) input = input[0 .. i];
        else if(mid < value) input = input[i + 1 .. $];
        else return true;
    }
    return false;
}

unittest
{
    assert(binarySearch([1, 3, 6, 7, 9, 15], 6));
    assert(!binarySearch([1, 3, 6, 7, 9, 15], 5));
}

编译时出现以下错误：

: Error: std.array could not be resolved - library reference missing?

但是，当我注释掉assert(binarySearch([1,3,6,7,9,15], 6));时，情节会变浓，因为这会产生一个非常奇怪的错误：

lolwtfbbqsauce

首先，缺少一个库，然后，它是一个16位应用程序。我知道这本书有一个勘误，但这不在其中。

更新

使用相同的代码编译rdmd test.d --main并出现以下错误

这次我做错了什么？ ：P

1 个答案:

答案 0 :(得分：2)

代码中没有错误 除此之外，它没有main函数，因此您无法运行已编译的程序。您可以要求编译器为您添加main函数。只需使用-main开关。

rdmd是DMD Script Shell 您会收到错误，因为rdmd将文件名后的所有参数视为程序的开关。试试rdmd --main test.d。
