adding modules to slackware's kernel

RaptorX · 03-24-2011, 02:26 PM

Hi guys.

I would like to recompile my kernel to add few modules to it but I would like to keep my current configuration so as not to have troubles with missing drivers for my hardware and stuff.

How do I do that?

(I did follow a kernel compile tutorial once but i am not sure if when i do that it deletes the current config)

Any help would be appreciated.

Your current configuration (compressed) should be found at /proc/config.gz. Copy that to your kernel source tree, uncompress it, rename it to .config - and there's your base config file. Then you can "make menuconfig" to make changes.

Copy the old .config file to the top level of your source and use make oldconfig instead of menuconfig.

Kind regards

I think what i needed was what AlukardZero mentioned. That should be the *current* configuration.

@AlukardZero
thanks a ton.

As I understand it, "make oldconfig" is for when you have a .config from a kernel older than the one you are building. I assumed when OP said "recompile my kernel" that he would be staying at the same kernel version. Correct me if menuconfig (first) isn't appropriate here.

Correct.

Code:

make oldconfig

sends out the new items added to a newer kernel than your currently running one (starting from the currently running config) to the console, asking what option you would like to set, while recompiling the same kernel version should get no output after this (anyway doing it does not harm).

Code:

make menuconfig

should be right here to go on reconfiguring your current setup.

Another tip:

Code:

zcat /proc/config.gz > .config

saves the current running kernel config in one step

Thanks for all the answers I was able to recompile without issues.
