生成命令後不生成.ko文件

我想編譯一個簡單的hello世界內核模塊，但在make命令之後，我收到下面的警告，並且不生成moduleName.ko文件。問題的原因是什麼？警告是否阻止生成.ko文件？我該如何解決這個問題？謝謝。生成命令後不生成.ko文件

make命令後輸出：

我覺得可變中號中缺少您的命令 - 它應該指向路徑模塊的源代碼位於：

make -C path-to-linux-src M=path-to-module-src modules

我使用SUBDIRS而不是M.我試着用M，但在輸出中我用M代替SUBDIRS得到了相同的結果。 – stedkka 2011-12-15 19:56:39

@stedkka在你的輸出中你沒有賦值給SUBDIR - 它應該是SUBDIR =路徑到你的模塊src – dimba 2011-12-15 20:05:59

使用make -C /lib/modules/2.6.20.15-custom/build M=$$PWD（$$PWD，也不需要modules）。
