Linux內核2.4.32編譯中多種函數的多重定義

Question

我將在x86_64系統中編譯linux內核2.4.32。

化妝DEP是確定的，但使bzImage的停止顯示像這樣的很多鏈接錯誤後：

在 kernel2.4.32 /包括目錄下有很多 ASM的目錄

每個屬於一個特定的體系結構（如asm-i386，asm-x86_64，asm-a64）

並且有一個單獨的asm鏈接到ASM-x86_64的目錄（因爲我的系統架構）目錄

當我從這兩個目錄之一ASM和ASM刪除與多個定義（如在錯誤列表set_64bit）功能-x86_64該錯誤將消失。

makefile或配置文件有問題嗎？爲什麼這些函數編譯多次？

懇求幫我...

Answer 1

的問題是從一個錯字功能在頭文件中定義@Tsyvarev已正確地提到。

這些有問題的功能定義必須從extern inline更改爲static inline。

此外，關於I/O的函數的定義，如inb, inw, inl, outb, outw, outl....必須在linux2.4.32/include/asm/io.h文件中更改，其中這些函數被定義爲具有extern關鍵字的宏！
