[Buildroot] Q. How to use a custom kernel tree?

[Buildroot] Q. How to use a custom kernel tree?

[Chris Wilkinson]

I have a customized, patched kernel tree which I'd like BR to use.

I tar'd the custom kernel tree, selected custom tarball for the kernel
version and put the full URL/path to the archive in
BR2_LINUX_KERNEL_CUSTOM_TARBALL.

The custom tree also contains a defconfig for my arch. I set
BR2_LINUX_KERNEL_USE_DEFCONFIG=y and gave it's name in
BR2_LINUX_KERNEL_DEFCONFIG.

Using make, BR error'ed out thus.

>>> linux custom Extracting
cat /home/chrisw/embedded/buildroot/dl/linux-3.4-ss4000e.tar | tar
--strip-components=1 -C
/home/chrisw/embedded/buildroot/output/build/linux-custom  -xf -
cat: /home/chrisw/embedded/buildroot/dl/linux-3.4-ss4000e.tar: No such file
or directory
tar: This does not look like a tar archive
tar: Exiting with failure status due to previous errors

It appears that BR expects to find the custom tarball in <BR>/dl, not the
path I specified.

What should I do to have BR use my custom kernel tree and config?

[Buildroot] Q. How to use a custom kernel tree?

[Jeremy Rosen]

simplest is to set a local.mk containing

LINUX_OVERRIDE_SRCDIR=<path to your uncompressed source>


this will use your directory as the sources.

there is also an option to specify the config file.

with those two you should be good

Can you pastebin your .config file somewhere?

Hum, let's see your .config first. Once we check that, we'll be able to
tell you if it's a configuration problem  or indeed a Buildroot bug.

Dear Jeremy Rosen,

Please don't top-post, this is annoying.

This doesn't really answers Chris question. The LINUX_OVERRIDE_SRCDIR
mechanism is usually meant to be useful during development, when you're
actively modifying your kernel tree.

Apparently, Chris is in a situation where he has some kernel sources
that don't change, and therefore he creates a tarball from them, and
expect Buildroot to be able to use this tarball. This can normally be
achieved using the BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION option,
which Chris rightly tried to use.

Hello Chris,

unfortunatelly, buildroot always assumes that the "custom tarball" is on
a server where it can be fetched using wget. I submitted a patch
(http://patchwork.ozlabs.org/patch/217204/) some time ago to improve
this, but noone responded.

You can use Source Override (see docu) to use your local kernel tree
(not gzipped).

Regards

Stephan

[Buildroot] Q. How to use a custom kernel tree?

[Jeremy Rosen]

ok, I misunderstood...

I thought he was actively developing and that he did the tarbal because
CUSTOM_TARBALL was the only way to override, not the other way round

my bad...

Can you please stop this horrible practice of top-posting?

Thanks!

[Chris Wilkinson]

Thanks for the tip. Where should this file be located? I read somewhere
else that it is at the root of the BR sources directory but I don't see
that in my BR tree.

My .config in in Pastebin here http://pastebin.com/6XDsAGzv

Pity this didn't get taken up. Perhaps it got overlooked. You could try
again possibly?

[Buildroot] Q. How to use a custom kernel tree?

[Chris Wilkinson]

Is this a config error on my part or a BR bug? Stephan suggests it's
currently a BR limitation that custom tarballs can only be got from an http
server not a local directory.

Yes, I think Stefan is correct. There is a patch pending to fix this
