在C++ builder中使用hashlib ++时出错？

Question

我下载了最新的hashlib ++ 0.32版本，并试图使用散列函数，但它说不支持编译器。

[BCC32 Fatal Error] hl_types.h(71): F1003 Error directive: "Unsuppported compiler."    "Please use GCC,MINGW,MSVC "   " or define hl_uint64 for your compiler in hl_types.h line 62" 

的hl_types.h看起来

我问有没有什么办法让它在Borland的C++ Builder的2010（BCC32）编译器的工作？

Answer 1

我认为错误消息几乎说该怎么办...添加如下头文件下面_MSC_VER检查等的最终的#else：

#elif defined(__BORLANDC__) 
typedef unsigned __int64 hl_uint64; 

（生成器具有“__int64”扩展整型）

Answer 2

“不支持编译”错误来自的代码表示的部分：

/** 
* at least 8 Byte 
*/ 
#ifdef __GNUC__ 
    typedef unsigned long long int hl_uint64; 
#elif __MINGW32__ 
    typedef unsigned long long int hl_uint64; 
#elif _MSC_VER 
    typedef unsigned __int64 hl_uint64; 
#else 
    #error "Unsuppported compiler." \ 
      "Please use GCC,MINGW,MSVC " \ 
     " or define hl_uint64 for your compiler in hl_types.h line 62" 
#endif 

你需要学会阅读错误消息，如果你打算做了很多节目。具体来说，该消息的部分表示“或在hl_types.h行62中为您的编译器定义hl_uint64”。您需要做的只是添加一行，用于标识该节中其他编译器的行中的64位整数类型。例如：

typedef unsigned long long hl_uint64; 

或者，如果Borland的，您可以访问stdint.h：

#include "stdint.h" 
typedef uint64_t hl_uint64;
