Re: [Ltib] Out of tree kernel and in-tree modules

[Vadim Lebedev]

Actually it is REALLY weird,

the device node files ARE created in the rootfs


Thanks

Vadim,

 

Did you run ./ltib -p <packagename> -m scdeploy ?

I did:

./ltib -m scdeploy  -p zaptel


I suppose it is equivalent

Thanks
Vadim

Stuart

Thanks a lot for the advice,

I'm now able to compile zaptel,
There is still a problmem with deploying
Somehow the zaptel build results are not installed into the rootfs
but in tmp/zaptel/opt/freescale/rootfs/arm

Any ideas?
Thanks
Vadim

Hello

I'm working with savannah ltib

I've somewhat unusual config:
I've have a kernel built out of LTIB tree 
but i have an in-tree kernel module (zaptel) which need to reference
the kernel's .config and .h files.
How can i arrange for this?

    

If you run $./ltib -m config you can select: "Include kernel headers" it
will install the kernel headers in rootfs/usr/src/linux/ and in your
spec file you can refer to these as (for example with see
dist/lfs-5.1/iproute/iproute.spec):
KERNEL_INCLUDE=$DEV_IMAGE/usr/src/linux 

Note also that config file gets put into rootfs/linux.config
($DEV_IMAGE/boot/linux.config).

If this is not enough and you need the whole built kernel tree left
unpacked, you can select (in ./ltib -m config):
"Leave the sources after building"

This will leave the built kernel sources unpacked in rpm/BUILD/linux and
you can refer to these from other spec files as: $RPM_BUILD_DIR/linux
See: dist/lfs-5.1/helloworld/hello_mod.spec for an example.

  

Antohere problem:
This time in-tree kernel for imx27ads
and still trying to build zaptel kernel module
the kerenel build's ok but when zaptel is compiled
it does not find   blablabla/linux/.config


I know it worked 2 monthes ago, but i'm unable to find what i'm
doing wrong this time.
    

I see that the kernel is built it's rpm is created and installed but
in the rpm/BUILD dirctory there is no linux directory  so zaptel build 
is screwed...

    

It's probably a change in configuration?  I don't understand though how
this can happen as if you look in config/userspace/packages.lkc you
should see:

config PKG_ZAPTEL
    bool "zaptel"
    select PKG_KERNEL_LEAVESRC

This should be enough to force the sources to remain unpacked.  Can you
run ./ltib -m config and scroll down to the kernel area and check that 
"Leave the sources after building" is enabled.

Regards, Stuart
