LDD编译错误

1,

错误:

make -C /lib/modules/2.6.32-21-generic/build M=/home/qwq/first/LDD/block/sbull modules
make[1]: 正在进入目录 `/usr/src/linux-headers-2.6.32-21-generic'
scripts/Makefile.build:49: *** CFLAGS was changed in "/home/qwq/first/LDD/block/sbull/Makefile". Fix it to use EXTRA_CFLAGS。 停止。
make[1]: *** [_module_/home/qwq/first/LDD/block/sbull] 错误 2
make[1]:正在离开目录 `/usr/src/linux-headers-2.6.32-21-generic'
make: *** [default] 错误 2

解决:

CFLAGS was changed Fix it to use EXTRA_CFLAGS

这个标志已经变了,把makefile中的 CFLAGS 替换威EXTRA_CFLAGS

/home/qwq/first/LDD/block/sbull/sbull.c: In function ‘sbull_xfer_request’:

解决:

The file include/linux/config.h has been removed from 2.6.18 kernel. So remember this if you build your favorite module against the new 2.6.19 kernel and you get an error。 Thats because there is no more include/linux/config.h file in 2.6.19.

Put linux/config.h out of its misery. 把这个头文件注释掉即可
