ubuntu module compilation for lpia when on hardy host and custom kernel

[Afzal, Naeem M]

Hi Guys,

I am having problem in figuring out how I can compile linux modules for a customer kernel (2.6.24-19-lpia). This is what I have done:

1. apt-get sources linux-image-2.6.24
2. cd /some/path/to/kernel/linux-2.6.24
3. modified config.lpia for options that need
4. dpkg-buildpackage -rfakroot -b -alpia
 I get all the deb packages

Now I want to use linux-modules-2.6.24-2.6.24 to compile against this kernel. I am not able to figure out how to point it my kernel which is not being installed on the host(Hardy 2.6.24-21-generic) I am building on.

5. I downloaded sources for ubuntu-modules
6. cd /some/other/patch/to/modules/linux-ubuntu-modules-2.6.24-2.6.24
7. copyover same config.lpia from kernel to debian/configs/lpia
7. ran same command "dpkg-buildpackage -rfakroot -b -alpia"  in modules directory

It is failing like for linux-ubuntu-modules as, any help is greatly appreciated

Regards
Naeem
