錯誤，而在Mac 10.6

編譯dsniff我得到這個錯誤時自動macport試圖編譯錯誤，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

這些意味着有類似的行：

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

還有就是「struct ether_addr」沒有事先聲明，這意味着，編譯器來治療它作爲僅具有函數聲明範圍的新類型。正如編譯器所指出的，這不是你想要的。您可以通過在聲明行之前解決該問題：

struct ether_addr;

這告訴編譯器最終會定義類型。在編譯器需要結構的內部細節之前，可以使用通常的C放棄指針來傳遞指針。

這些錯誤告訴你有什麼東西嚴重誤入歧途。該代碼假定ETH_H將被定義，但事實並非如此。

還有其他聲明與代碼所配置的期望不同，這會導致文件中的警告進一步發生。有可能是'沒有強制轉換的指針'的問題是沒有聲明的函數，所以它們被認爲是返回一個整數的函數，但它們實際上是返回'char *'的函數，因此應該聲明。

當我試圖編譯dsniff時，配置階段失敗，因爲它沒有找到'libnet'。

所以：

確保你有手頭上的相關庫（如果你已經有了相關的URL「的libnet」這將是有益的），以及相關的報頭。
查看配置輸出;它可能不會分析需要分析的所有內容。
查看您是否可以找到關於爲MacOS X或其中一個BSD版本編譯dsniff的信息（MacOS X/Darwin有點類似於Unix的BSD版本）。
