editing a kernel module make file

shanenin · 11-09-2005, 03:47 PM

I am need to edit a Makefile that is used to install the fusion kernel module. The Makefile checks the output of uname -r to determine the module build directory. Here is the original code

Code:

KERNEL_MODLIB     = /lib/modules/$(shell uname -r)
KERNEL_SOURCE     = $(KERNEL_MODLIB)/build
KERNEL_PATCHLEVEL = $(shell uname -r | cut -d . -f 2)

since I am building this system on a chrooted system, I could not use the output of uname -r, so I did this. The module seemed to build correctly.

Code:

KERNEL_MODLIB     = /lib/modules/$(shell ls /lib/modules)
KERNEL_SOURCE     = $(KERNEL_MODLIB)/build
KERNEL_PATCHLEVEL = 6

the problem is coming when I run make install. It errors out with the depmod command. by default depmod checks uname -r, but since my chrroted system has a differnt module directroy then uname -r returns it erros out.

question:

How can I specify depmod to use a specific module diretory then the directoy specified by uname -r.

if you care to look, this is the code used in the Makefile

Code:

(if test $(KERNEL_PATCHLEVEL) = 4; then cp $(SUB)/fusion.o $(KERNEL_MODLIB); else cp $(SUB)/fusion.ko $(KERNEL_MODLIB); fi) && depmod -ae

Man depmod says :

Code:

...
OPTIONS
       -b basedir --basedir basedir
                 If your modules are not currently in the (normal) directory /lib/modules/version, but in  a
                 staging  area,  you  can  specify a basedir which is prepended to the directory name.  This
                 basedir is stripped from the resulting modules.dep file, so it is ready to  be  moved  into
                 the normal location.
