错误，而在Mac 10.6

编译dsniff我得到这个错误时自动macport试图编译错误，而在Mac 10.6

任何想法？

第一警告：

./arpspoof.c:25: warning: 'struct ether_addr' declared inside parameter list 
./arpspoof.c:25: warning: its scope is only this definition or declaration, 
          which is probably not what you want 
./arpspoof.c:26: warning: 'struct ether_addr' declared inside parameter list

这些意味着有类似的行：

extern somefunc(struct ether_addr *arg1, ...);

还有就是“struct ether_addr”没有事先声明，这意味着，编译器来治疗它作为仅具有函数声明范围的新类型。正如编译器所指出的，这不是你想要的。您可以通过在声明行之前解决该问题：

struct ether_addr;

这告诉编译器最终会定义类型。在编译器需要结构的内部细节之前，可以使用通常的C放弃指针来传递指针。

这些错误告诉你有什么东西严重误入歧途。该代码假定ETH_H将被定义，但事实并非如此。

还有其他声明与代码所配置的期望不同，这会导致文件中的警告进一步发生。有可能是'没有强制转换的指针'的问题是没有声明的函数，所以它们被认为是返回一个整数的函数，但它们实际上是返回'char *'的函数，因此应该声明。

当我试图编译dsniff时，配置阶段失败，因为它没有找到'libnet'。

所以：

确保你有手头上的相关库（如果你已经有了相关的URL“的libnet”这将是有益的），以及相关的报头。
查看配置输出;它可能不会分析需要分析的所有内容。
查看您是否可以找到关于为MacOS X或其中一个BSD版本编译dsniff的信息（MacOS X/Darwin有点类似于Unix的BSD版本）。
