CentOS - Mar 2006 - Has anybody recompiled Centos'' default kernel on x86_64

I haven''t been able to recompile Centos'' default kernel on
4.2, nor on 4.3 on an x86_64
   
  The process fails with two different problems:
   
  1. ''cannot find -lqt'' error
   
  2. offset.h.tmp missing
   
  Kind of weird not being able to recompile an integral part of the system on a
system which is entirely based on recompilation.
   
  Based on second hand reports vanila kernel seems to compile o.k., but I
don''t want to go vanila if I don''t have to.

All released CentOS kernels are built on CentOS itself. What version are 
you trying to build ?

I''m trying to compile the default, ''regular'', x86_64
kernel the one that comes with 4.3 in a Centos 4.3
x86_64 environment containig strictly default Centos
4.3 packages.

Of not too much to ask, the annaconda file of a Centos
x86_64 environment that will built Centos kernel for
the x86_64 will be greatly appreciated.

You will get that error on x86_64 if you try and run ''make
xconfig'' on
the source tree that is extracted after, for example, running ''rpmbuild
-bp''

As the normal build process is all command line driven, then this is not 
a problem.

There are a few patches out there to work round this (and I believe
it''s
fixed in more recent kernels). The patch I use which works for me is 
attached.

well, 2.6.9-34.EL is the kernel version included in 4.3 and i can 
confirm it builds fine on a centos 4.3/x86_64 machine running 2.6.9-34.EL

anaconda has nothing to do with rpm or the build process. so i have no 
idea what you are talking about.

I can confirm that it doesn''t build.  One more person
can confirm the same thing.  The same exact kernel
compilation errors were in Centos 4.2.  Thread on
Centos forum discussing the problem:

http://www.centos.org/modules/newbb/viewtopic.php?topic_id=3519&forum=34

An anaconda file would provide the EXACT environment
on two different machines.  Right now the problem is
in the "you say it works, and I say it doesn''t work"
stage.  

Right now you:

I say:

On Centos installation (no non Centos packages
installed) on an x86_64, Cento''s kernel 2.6.9-34.EL
fails to compiles.  See
http://www.centos.org/modules/newbb/viewtopic.php?topic_id=3519&forum=34
on how it fails.

Either you are right and I''m wrong, or you are wrong
and I''m right.  I can provide you with the environemnt
(anaconda file)where the kernel fails to compile.  Can
you provide the environment (anaconda file) where the
kenrel can be compiled?

TIA

James,

I was able to get arround the ''cannot find -lqt'' error
using make gconfig

Now when I make bzImage it fails with offset.h.tmp
missing error.

Thanks

install a 64bit clean machine, install everything. thats how the centos 
buildsystems are setup.

I know it builds because the kernel in the distro is the one that i built!

setup a userlevel rpmroot, install the src.rpm file, ''rpmbuild -ba 
kernel-2.6.spec'' and post the buildlog somewhere, post a url to the 
buildlog here in the list. please dont send the entire buildlog to the list.

is there a reason you are not trying to build it from the .spec file ?

I''m not in front of the machine right now, so the info
below is from memory.  

cd /usr/src/kernel/kernel*
make mrproper
make [x,g]config
##xconfig failed, gconfig worked after installing a
couple of packages
##configure the kernel
##save information
make bzImage
##fails with the offset.h.tmp error
##rest of the procedure if make bzImage is successful
make modules
make modules_install
make install



thanks

This is fine for the old days, but there are new methods for doing
this if you''re just rebuilding the stock x86_64 kernel rpm

The short answer is->
 rpm -i kernel-2.6.9-34.src.rpm
rpmbuild -bp $BUILDDIR/SPECS/kernel.spec --target=x86_64

this will give you the patched kernel tree

edit the appropriate config in $BUILDDIR/SOURCES/config-2.6.9-34x86_64
rpmbuild -bs $BUILDDIR/SPECS/kernel.spec --target=x86_64
to rebuild the src.rpm with your changes

rpmbuild --rebuild $BUILDDIR/SRPMS/kernel-blah --target=x86_64

then install the new kernel rpms.

That''s off the top of my head, there may be a typo or two, but
that''s
the right direction.
