Answer 1

猜测：您没有在自定义Makefile中设置M环境变量。见http://tldp.org/LDP/lkmpg/2.6/html/x181.html

下一次，请确实提出一个比“错误？”更具体的问题。

Answer 2

我对make的任何问题都提出异议。不过，我很确定你的Makefile有问题。根据一些随机的网络搜索，尝试这样的事情：

make -C /lib/modules/2.6.32-5-686/build SUBDIRS=/home/mgh/Documents modules

这假设您的Makefile位于/home/mgh/Documents。

make有什么问题？
