在 C++ 构建器中使用 hashlib++ 时出错？

Question

我下载了最新的 hashlib++ 0.32 版本并尝试使用哈希函数，但它显示 Unsupported compiler。

[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"

hl_types.h 看起来

我想问有没有办法让它在 Borland C++ builder 2010 (BCC32) 编译器中工作？

Answer 1

我认为错误消息几乎说明了该怎么做...将以下内容添加到_MSC_VER检查下方和最终#else上方的头文件中：

#elif defined( __BORLANDC__ )
typedef unsigned __int64 hl_uint64;

（生成器具有“__int64”扩展整数类型）

Answer 2

“不支持的编译器”错误来自以下代码部分：

/**
* 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

如果您要进行大量编程，则需要学习阅读错误消息。具体来说，消息中显示“或在 hl_types.h 第 62 行为您的编译器定义 hl_uint64”的部分。您需要做的就是在该部分中的其他编译器的行中添加一个标识 64 位整数类型的行。例如：

typedef unsigned long long hl_uint64;

或者，如果 Borland 允许您访问 stdint.h：

#include "stdint.h"
typedef uint64_t hl_uint64;
