我使用 Ubuntu 10.10 - 2.6.35.23-generic
我想编译 lincan 模块 (http://sourceforge.net/projects/ocera/)，但它不像我想要的那样工作……这是我第一次编译内核模块。我这样做了：
首先将 lincan-sources 解压缩到我的主目录。然后用这个输出执行“make”：
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 ;

然后我输入“make install”：
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'
它什么也没发生。我发现没有内核模块。我做错了什么？为什么没有 autoconf.h 和其他文件？你对我有什么提示吗？谢谢！
现在我为丢失的文件（autoconf.h 和 utsrelease.h）创建了硬链接。它们位于 /usr/src/linux-headers-2.6.35.23-generic/include/generated/
现在它编译更多。这是出现的第一个错误：
