Custom kernel compress module
« on: September 19, 2012, 10:51:07 AM »
Hi,

I've been looking on this forum , and also asked google, but can't find a solution.
When compiling a custom kernel , I can't get the modules compressed.
So I wonder how it's done.

btw I'm compiling the same current kernel (3.0.21), and also the same config.
With only the remove of a reboot quirk in reboot.c , for the compulab fitpc2
This Quirk doesn't work anymore in 3.x kernels , and has to be removed.
I've already tested with uncompressed modules , and this is working fine.

Kind regards,

Cuppie

Thanks for the quick reply,

So it's done via some kind of script, is it possible to get it somehow?

On the other hand , I'm thinking about the need of compiling all modules again.
I'm using the same kernel.
I'm just testing the custom with the original compressed modules , and so far it seems to work fine.

An alternative might be to use GNU gzip with the "-r" option, i.e.:
"gzip -9r *ko"

A change like that should be compatible with the current modules, yes.

If this is still an issue with the latest Linus' kernel, please report it to kernel.org too.

Well... it's okay to compress all modules manually, but what do I do with modules.dep? Do I have to edit it manually to append '.gz' substring to each module name? Hm...
