Hi there,

The config file that is used for our kernel make is pulled from another location (arch/.../configs/ instead of just .config). This means that every time I do 'make menuconfig' I have to select 'Load alternative config' and then paste in the location.

Is there anyway to change the default config location for menuconfig OR some script that could start menuconfig with that config file?

Could potentially save me a lot of time

Thanks,
Austin.

Are you saying that you are in your kernel source directory and then copy the config file that you want to use to ./.config and then make menuconfig and it does not use the config that you copied to .config?

Hi Austin,

I'm trying to figure out what it is you want to do, so a few examples from me first...

Usually when I configure a new kernel I base it on the old config file found in /boot
..which is the status of my running kernel.

I do this with...

/usr/src/linux is a link to my new kernel file... /usr/src/2.6.37-tmb-0.rc5.1mdv

I make the link by first removing the old kernel link...and creating a new one pointing to the new sources.
then...
This usually brings up a pile of questions/options that have either changed or are new.
(between the old kernel config and the new kernel options.)

does this look like your situation?

Regards Glenn

Thanks for your replies. I think I should have mentioned that I am developing for an embedded application, not trying to recompile the kernel I am running.

To compile the kernel for the target I call make linux from the parent directory of the linux source. This makefile uses the config file located: linux/arch/arm/configs/myconfigfile. I can't change this.

When I want to change the kernel options I have to go to the linux directory, call make menuconfig, select Load an Alternative Configuration File, and enter the location linux/arch/arm/configs/myconfigfile. This is the step that I would like to automate.

I would have hoped you could just call something like make menuconfig linux/arch/arm/configs/myconfigfile but that function does seem to exist. I tried making a simbolic link between linux/arch/arm/configs/myconfigfile and linux/.config but when I run make menuconfig, instead of opening it, it just overwrites that link with a file of the same name.

I hope that makes more sense. I know it is a rather specific problem. I appreciate you having a think about it.

You got me!

How about a script that automates the whole process.

Afterall the .config file is just a text file.

Why use menuconfig or xconfig at all?

If you know where everything is, and it doesn't change too often, a shell script may be a viable alternative.

within a script you may use grep to find and sed to edit the file, possibly with vi.

I'm still learning about these tools, sorry I don't have a solution.

but I hope this helps.

Regards Glenn

ps. a guide I have been using for scripting with sed, grep awk and vi.

Try this:

make menuconfig KCONFIG_CONFIG=linux/arch/arm/configs/myconfigfile
