How can i save my new kernel configuration

[ggeo]

Hello

I use fedora 7,KDE
I just modified my kernel (with make menuconfig).

I saved it and at console i wrote :

make all modules_install install

and it gave me :

HOSTLD scripts/kconfig/conf
scripts/kconfig/conf -s arch/x86_64/Kconfig
#
# configuration written to .config
#
CHK include/linux/version.h
CHK include/linux/utsrelease.h
make[1]: *** No rule to make target `missing-syscalls'. Stop.
make: *** [prepare0] Error 2

What i am supposed to do?What command should i use?

Thanks!

Here is what you should do.
Make the changes as needed.
Save to a file first.
Then select save
And finally exit.

If you only added things as modules then you can run this command.
make modules
make modules_install
depmod -a

If you removed or added anything to be part of the kernel then you have use this first.
make

make will build the kernel and the modules. make modules_install to install the modules in /lib/`uname -r` and make install to add to grub and created the initrd file. This is my normal step for building kernel in 2.6

make xconfig
make
make module_install
make install

Hello

I did again my changes to kernel and when i run make it gives me :

CHK include/linux/version.h
CHK include/linux/utsrelease.h
make[1]: *** No rule to make target `missing-syscalls'. Stop.
make: *** [prepare0] Error 2

What can i do now?
Thanks!

Are you recompiling the existing kernel from the kernel-devel-***.rpm. Fedora pathces the crap out of this kernels. If so I would download a clean kernel from www.kernel.org and build that one.

Hello

I have no idea what to do with the kernel from kernel.org and i think it has a lot of work ?

(I must mention that i did the make menuconfig in /usr/src/kernels/2.6.22.5-76.fc7-x86_64
i suppose its right?)

Thanks

I got the answer I mention from doing a google search on the error you had. Read a couple of the search answers and both mention getting a clean source. You can use the *.config file in /boot and load it first to get a close setup as the current Redhat kernel. Then make the needed changes and build.

Thanks,

I will see what i can do.if i can find sth else..

Hello

I followed the instructions here :http:// fedoraproject.org/wiki/Docs/CustomKernel

and i stuck in the command

rpmbuild -bp --target='x86_64' kernel-2.6.spec

It gives me the prompt :

-sh-3.2$

If i write it like:

rpmbuild -bp --target=x86_64 kernel-2.6.spec

(without the ' ' )
it gives :

Building target platforms: x86_64
Building for target x86_64
error: Failed build dependencies:
sparse >= 0.3 is needed by kernel-2.6.22.5-76.fc7.x86_64

It supposes to build the
~/rpmbuild/BUILD/kernel-<version>/linux-<version>.<arch> directory

Thanks

I never could understand why you would use the src.rpm to build rpm files that already are available.

Hello

I am not familiar with all the kernel thing so i try to do some reading to see what can i do.
And some times i don't know what am i doing..

All i want is load and unload some things from the kernel!
I thought it was simple.

make menuconfig
save
make
make modules_install
make install

and that's it!!

But ..it is not

I got the answer I mention from doing a google search on the error you had. Read a couple of the search answers and both mention getting a clean source. You can use the *.config file in /boot and load it first to get a close setup as the current Redhat kernel. Then make the needed changes and build.

I did that but i have the same problem,so i tried to build from src.rpm


Thanks!

Out of ideas if a new plain vanilla kernel will not compile.

Brian

[ggeo]

Hello

Any ideas ??

[nishantnahsin]

First, thanks for telling me that the kernel-devel and kernel-source packages are useless.

Second building a kernel obtained from kernel.org is relatively straightforward.

THIS is a place that'll give all the required guidance.

Also, the existing kernel is in the form of a bzImage so if you make a bzImage from the kernel source you can pretty much copy paste the bootloader configuration.

best of luck
