More on that later. No. No more on that later. It was deserved. You failed to provide proper documentation of what you were doing and on what system in addition to not following the recommendations of the channel moderators. Also, the irc channel is for centos support, not for supporting custom kernels on gentoo. > Here is the deal, I am in the process of installing Gentoo on a AMD64 > server.

You'll need these for the kernel to build properly, at which point it will probably be incompatible with gentoo because of rhel specific requirements or expectations. > After messing with that for days, patches and all.

It's just what you need to build against the kernel, not to build a new kernel. > When I attempt to do the same with the x86_64 one I get > > wlt 2.6.9-22.EL # make bzImage ARCH=x86_64 V=1 > if /usr/bin/env test ! /usr/src/2.6.9-22.EL -ef /usr/src/2.6.9-22.EL; > then \ > /bin/sh /usr/src/2.6.9-22.EL/scripts/mkmakefile \ > /usr/src/2.6.9-22.EL /usr/src/2.6.9-22.EL 2 6 \ > > /usr/src/2.6.9-22.EL/Makefile; \ > fi > CHK include/linux/version.h > CHK include/asm-x86_64/offset.h > make -f scripts/Makefile.build obj=scripts/basic > make -f scripts/Makefile.build obj=scripts > make -f scripts/Makefile.build obj=scripts/mod > make -f scripts/Makefile.build obj=init > make[1]: *** No rule to make target `init/main.o', needed by > `init/built-in.o'.

You're not paying anything for the distribution, and you're not RUNNING the distribution, you're building its kernel outside of its environment.

You can't expect to mix and match between the two. 2.6.9.11 has been updated for security reasons.

It's possible that the patches create the additional files you need. or that somewhere through this nightmare of a build process something failed silently or was excluded. > I am really trying to avoid rebuilding a rpm.

We don't have problems with questions that apply to centos. Yours applies to gentoo. Asking a gentoo question in #centos is akin to asking for a mcdonalds happy meal at a pizza shop. > Just how to get a custom x86_64 kernel built using CentOS 2.6.9-22 > sources. I doubt this will work for you. Honestly. Trade in your hardware for something that works with your preferred distro instead of attempting this travesty.
