编译Linux内核模块（lincan）

Question

我使用Ubuntu 10.10 - 2.6.35.23泛型

我想编译lincan模块（http://sourceforge.net/projects/ocera/），但它不不像我想要的那样工作......这是我第一次编译内核模块。我这样做：

首先解压lincan-sources到我的主目录。然后excecuted “做” 与此输出：

make -C /home/x/can/lincan-0.3.4/src SOURCES_DIR=/home/x/can/lincan-0.3.4/src default ; make -C /home/x/can/lincan-0.3.4/utils SOURCES_DIR=/home/x/can/lincan-0.3.4/utils default ;

make[1]: Verlasse Verzeichnis '/home/x/can/lincan-0.3.4/utils' 

然后我输入 “make安装”：

make -C /home/x/can/lincan-0.3.4/src SOURCES_DIR=/home/x/can/lincan-0.3.4/src install ; make -C /home/x/can/lincan-0.3.4/utils SOURCES_DIR=/home/x/can/lincan-0.3.4/utils install ;

echo Nothing to install 
Nothing to install 
make[1]: Verlasse Verzeichnis '/home/x/can/lincan-0.3.4/utils' 

而且它的发生无关。我找不到内核模块。我错了什么？为什么没有autoconf.h和其他文件？你有什么提示吗？谢谢！

现在我创建了缺少文件（autoconf.h和utsrelease.h）的硬链接。它们位于/usr/src/linux-headers-2.6.35.23-generic/include/generated/

现在它编译得更多了。这是出现的第一个错误：

Answer 1

现在我创建硬链接为丢失的文件（autoconf.h和utsrelease.h）。

您必须安装含有构建环境创建为正在运行的内核生成时的包。源代码通常是毫无意义的（无论如何，当你打算构建一个外部模块时，你想要什么，比如8139too.c），除了内核头文件。我不能说构建环境位于Debian或其后代的哪个位置，但在openSUSE中将包含一个“kernel-default-devel”包，例如包含utsrelease.h和autoconf.h，以及 - 通过依赖关系 - 静态头文件需要的文件。因此，寻找一个包含这个的预先存在的deb包。

Answer 2

请安装给定的内核构建先决条件here.这将安装必要的工具来构建/编译内核模块。
