Hi,
My jobs need to recompile the kernel codes, but I don't know how to yum the kernel source codes.
Any help?
Thanks in advance.

First look in http://wiki.centos.org/HowTos/I_need_the_Kernel_Source
and then http://wiki.centos.org/HowTos/Custom_Kernel
Akemi
I have downloaded the src.rpm according the wiki instructions. however, when I executed
$ rpm -i kernel-2.6.18-92.1.10.el5.src.rpm
I got a lot of warnings and after the following command:
$ rpmbuild -bp --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log
No files are created in BUILD directory. The prep-err.log said:
error: Failed build dependencies: unifdef is needed by kernel-2.6.18-92.1.10.el5.x86_64
My hardware is a 64bit machine. Are there something different in kernel version 32 and 64? or, something I miss?
Thanks again,
Ian

Do you have installed kernel-devel package?

Rather than guessing, why not look at the output from the rpm command he ran, which gives the name of the package he's missing? Filipe nailed this one a little earlier in the thread with unifdef.x86_64 needing to be installed.

I remember running into this a while back. That being the case, shouldn't unifdef be included in kernel-devel, or at least one of the packages that are required for building a kernel? Seems like it sticks out like a sore thumb this way....
Alternatively, how do I go about suggesting this in a formal way (bugzilla, etc.)?
Thanks.

Alan and I are now talking about this so we can amend the Wiki article appropriately. According to him, unifdef is not required on his 32-bit system. I will update on this subject as soon as I gather more info.

You can certainly help. So, from what you wrote I suppose you encountered the same dependency problem and then manually installed unifdef. Was this indeed the case? Also, this happened on an x86_64 system?

Yes, yes, and yes, not necessarily in that order.... ;^)
I routinely build a kernel with NTFS read/write support whenever a new kernel comes out, partly to get the support, but mostly to keep my hand at building kernels alive and kicking (?). My primary desktop is an AMD 64x2 and I always run CentOS x86_64 kernels.

this is OT, but do you know you can get NTFS RW support by simply installing fuse-ntfs-3g from rpmforge? Fuse (from rf) gets rebuilt for new kernels by dkms, so it's painless on kernel updates.

When you ran:
yum install fuse fuse-ntfs-3g dkms dkms-fuse
did it go without any error? If so, I suggest you do a reboot. You don't have to, but it is the easiest to get dkms into action.

Sure. You just tried to execute a partition.
You are correct Ralph. I copied what was on the wiki page and pasted and I changed to hda6 and that is exactly what it did.

Just an FYI Lanny. Keep in mind that you can test (or use for real too) with a manual version of that information in a CLI mount (see man mount). E.g.
# mount -t ntfs-3g -o rw,umask=0000 /dev/hda6 /mnt/win
It might be easier to see the correlation if you also review "man fstab".

Yes, but the point isn't to make it painless, it's to make sure I can keep in practice. I've had jobs over the last 9 years doing Linux kernel development/analysis, and at one point I was so out of practice I had to relearn how to build the kernel all over again. /That/ was painful.
BTW, since you mentioned it, which is better - the RH NTFS module(s) or the fuse implementation? Maybe I'll look for another excuse to build a modified kernel if the latter....

Well... if you go for the fuse/dkms route, you will lose the chance to build the module upon kernel update. :-)

Well you can always do what I did a few years back. "In days of yore, long ago" I had a LAN using some coax and ethernet cards leftover from my early Lantastic installation. Cards were a mixed bag Including some IBM ones that had both RJ-45 and BNC ports. At the time the drivers (for Crystal chips) had no support for the BNC ports and didn't allow use of all the chipset features.
I jumped in to the source and I WAS AGHAST! It was the crappiest, least structured, most obfuscated mess I had ever seen.
Falling back to my former life, I hollered "REWRITE, YES" (accompanied by rapid pumping of right fist upon slightly bent knee! :-))
So I went to the web site, downloaded the docs, learned how it was supposed to work and started re-work. I didn't do the whole job, but annotated and restructured the parts I had to touch.
I then maintained it of many version of the kernel and driver.
Since I was doing LFS at the time, it sometimes got interesting.
But it did keep my in practice building kernels, modules and making patches.
Maybe that's a possibility for you? A nice side-effect is being able to help occasionally when some poses a question about what you been working on. For me, a lot of satisfaction came when I was able to help the LFS list users when they had networking problems - "peripheral learning effect".

Rather than guessing, why not look at the output from the rpm command he ran, which gives the name of the package he's missing? Filipe nailed this one a little earlier in the thread with unifdef.x86_64 needing to be installed.
I remember running into this a while back. That being the case, shouldn't unifdef be included in kernel-devel, or at least one of the packages that are required for building a kernel? Seems like it sticks out like a sore thumb this way....
Alternatively, how do I go about suggesting this in a formal way (bugzilla, etc.)?
Alan and I are now talking about this so we can amend the Wiki article appropriately. According to him, unifdef is not required on his 32-bit system. I will update on this subject as soon as I gather more info.
I've needed it on RHEL 5 systems before I could build the kernel source on 32 bit systems. I probably did with CentOS too, but I don't recall for sure.

I should have updated this thread earlier. I have confirmed that unifdef is required when building kernels for x86_64 but not for i686.
It's in the kernel .spec file:
# no need to build headers again for these arches, # they can just use i386 and ppc64 headers %ifarch i586 i686 ppc64iseries %define with_headers 0 %endif
and this:
%if %{with_headers} BuildRequires: unifdef %endif
We have since updated the Wiki article accordingly. Thank you all for your participation.

Yum is your friend.
$ yum whatprovides unifdef ... unifdef.x86_64 : Unifdef tool for removing ifdef'd lines

My jobs need to recompile the kernel codes, but I don't know how to yum the kernel source codes.
This should download the .src RPM in the current dir:
yumdownloader --source kernel
yum-utils should be installed first.
