在64位機上彙編問題的原始套接字

我想要做一些原始套接字編程。我有一些編譯/運行在32位機器上的示例代碼，但是當我嘗試在64位機器上編譯相同的代碼時，我得到了/ usr/includes/sys和/ usr/includes/linux頭文件之間的差異。我原以爲在64位機器上，所有的頭文件已經被「糾正」了64位的使用。有人可以給我一些關於如何解決這個問題的指針。我使用的是linux（fedora 9 64bit），GCC 4.3.2在64位機上彙編問題的原始套接字

謝謝！

我編譯如下：GCC -Wall -o服務器server.c並得到以下錯誤：

你不應該包括從Linux /東西，這是不支持的用戶空間程序。

它也看起來好像你缺少一些包含，因爲你得到htons()的警告。

此外，您應該在格式字符串中使用%ld，而不僅僅是%d來打印long int變量。

根據代碼我想你可以使用「linux includes」，因爲我試圖在以太網層發送/接收數據包。（我沒有做ICMP或ping或任何這樣的事情，但做我自己的事情）。我試圖刪除他們，但後來我得到更多的錯誤。你是說在linux頭文件中定義的所有內容都應該放在「userland」頭文件中？ – NomadAlien 2010-01-18 08:14:10

@ nomad.alien：這就是我的想法，是的......儘管如此，我似乎無法挖掘參考。但是，您收到的所有重複警告都表明您包含的內容超出了您的需要。我想，如果你發佈了一些骨架代碼，我會更容易。 – unwind 2010-01-18 08:26:28

好的，謝謝大家的提示。我會嘗試一些提到的事情，如果這不起作用，我會發布一些代碼。 – NomadAlien 2010-01-18 18:27:26

假設您的編譯環境是正確的，我懷疑C宏定義爲不應該定義，或者定義了不應該定義的宏，並且這導致了不兼容的類型定義。查看有問題的頭文件以確定該宏可能是什麼。
