[TriLUG] Kernel module config Question

[Marty Ferguson]

I think that if you want to compile only the one new
module without recompiling the kernel, then you
don't want to make mrproper or make clean either.

Make dep will take care of gleaning dependencies,
but making clean will get rid of too much stuff  out
of /usr/src/linux-2.4 directory tree that a 
module-only compile would need.  

I've never attempted this.  I assume Red Hat 7.X, 
or a derivative like Mandrake.

I think you'll want to identify a temporary EXTRAVERSION 
so there is a kernel ID to hold your new target module.

Modify the 4th line of the make file EXTRAVERSION

EXTRAVERSION = TMP

backup
make menuconfig
make dep
make modules
make modules_install

Check for the existance of the new module in 
/lib/modules/2.4.X-TMP/kernel

copy it over to the corresponding directory of the 
live kernel you are now running 

test, insmod my_new_module

It will either work or complain.  If it complains, 
then you'll probably need to compile the entire 
kernel, but then after that if it's a good kernel,
and it boots and runs properly, then you may 
thereafter only need to follow the above 
steps.
