I¹m trying to build a 2.6.18-128.1.6.el5 kernel without kabichk. I have downloaded the sources, installed the compiler, etc and ran the following command
rpmbuild -bb --target=`uname -m` --without kabichk --with baseonly --without debug \ --without debuginfo kernel-2.6.spec.
I had modified the .SPEC file according to the WIKI page http://wiki.centos.org/HowTos/Custom_Kernel
I have NOT installed any patches that will break KABI, but I am wanting to patch the kernel for SCST, and that will do it. Currently, I¹m just trying to get the beast to build. I have been successful getting this to work on older versions like 2.6.18-92.1.22, but I have not had success with 128.1.6. l. I have not worried about build errors at this point, because I¹m hoping someone can say, ³Just do this, and all will be well.²
I am relatively new to CentOS / RedHat, but I do have a significant amount of Linux experience building kernels.
I am now trying to see if I can get the kernel to build with kabi in place.
Any pointers would be greatly appreciated. TIA.

If you know your custom kernel retains the kABI, I suggest you entirely skip the section of the Wiki article that deals with the kABI-related modifications. No only this will reduce the chance of making incorrect changes but also it is indeed a good idea to do kABI checking.
If the build still fails, please post the last portion of the error log (or e-mail the whole log file to me).

For the most part, the build instructions on the link work for me. The only changes I do is to install rpmdevtools first, then run rpmdev-setuptree to create the rpmbuild directories and .rpmmacros file. The x86_64 also had a requirement for the unifdef package.

Did you get it to build with kabichk turned off?
I had gotten older packages to build as below, but 128.1.6 was giving errors. I can get the kernel to build with kabichk turned on with no real problems. Also here are the kernel packages I have installed (plus the source of course.....)
rpm -qa | grep kernel kernel-2.6.18-92.el5 kernel-devel-2.6.18-128.1.6.el5 kernel-headers-2.6.18-128.1.6.el5 kernel-2.6.18-128.1.6.el5 kernel-2.6.18-92.1.22.el5SCST - This was the one that I built and it worked

Yes, this one from my stderr capture:
In file included from fs/ocfs2/ocfs2.h:45, from fs/ocfs2/alloc.c:34:fs/ocfs2/endian.h:26: error: redefinition of 'le16_add_cpu' include/linux/byteorder/generic.h:174: error: previous definition of 'le16_add_cpu' was herefs/ocfs2/endian.h:31: error: redefinition of 'le32_add_cpu' include/linux/byteorder/generic.h:179: error: previous definition of 'le32_add_cpu' was herefs/ocfs2/endian.h:41: error: redefinition of 'be32_add_cpu' include/linux/byteorder/generic.h:195: error: previous definition of 'be32_add_cpu' was here make[2]: *** [fs/ocfs2/alloc.o] Error 1 make[1]: *** [fs/ocfs2] Error 2 make: *** [fs] Error 2 make: *** Waiting for unfinished jobs....
That was all I found.

Ahh.. It has failed without kabichk. I can't troubleshoot at the moment though but there are multiple errors.
I had gotten older packages to build as below, but 128.1.6 was giving errors. I can get the kernel to build with kabichk turned on with no real problems. Also here are the kernel packages I have installed (plus the source of course.....)
As someone else suggested, perhaps disabling those failed modules may get us past the build error.

Terry: Have you applied the patch referenced in the bugzilla on the CentOS wiki:
https://bugzilla.redhat.com/show_bug.cgi?id=456765 https://bugzilla.redhat.com/attachment.cgi?id=332650
It differs somewhat from the patches in the kabi section of the howto... i.e., changes the beginning of the %if block.
Thanks Kwan
