I don&#39;t understand how to update the kernel Makefile for modules install

--- Makefile    2006/01/26 06:13:18    1.1

That&#39;s a format of diff/patch command.

You can use editor, open Makefile, go to line 897,

it was,

depmod_opts := -b $(INSTALL_MOD_PATH)/lib/modules -r

change it to

depmod_opts := -b $(INSTALL_MOD_PATH) -r

Do you remember, we have several "patch" commands in the post?

A patch file is generated with the "diff" command. When we change some files, we can find the differences from what they were before we change. Send only the change to others, and he can update the files with "patch" command.

So if you save the "diff" to a file, Makefile.diff

you can update without using editor, with the command

cd ~/linux-2.6.x
patch -p0 <Makefile.diff

The parameter "-p0" mean cut zero dir level from file header, ie, the files in diff are in the same directory. Sometime, we use "-p1", we cut one level dir level from file header. eg, "linux-2.6.x/Makefile" with "-p1" will be the same as "Makefile" with "-p0" .
