Hello, First of all, you have to set md as a module. In /usrc/src/linux, run make menuconfig, and configure md driver to be compiled as a module [M]. Then, I think you have two options here : - If you really want to build md (or any module) in a separate directory, you will have to play with the kernel Makefile params, such as SUBDIR and MODVERDIR. Have a look on out-of-kernel drivers, such as madwifi, which uses these kind of building [http://madwifi.org/]. - Modify md source in-place, in /usr/src/kernel/drivers/md, and build up as modules here. It seems to me like you're modifying code out of the tree, and inserting after. BTW, how do you compile your kernel ? Do you have any kind of distro-specific way to build it ? Maybe a simple make modules && make modules_install (from /usr/src/linux) would be enough to achieve what you want to do... - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
