genkernel output including build failure
On a fresh system, with =sys-kernel/gentoo-sources-3.3.8 and =sys-kernel/genkernel-3.4.24_p1, I tried to build my kernel, modules and initramfs using this command:
genkernel --kernel-config=/root/kernel-config all
I get a build failure:
util-linux/mkfs_ext2.c:51:27: fatal error: linux/ext2_fs.h: No such file or directory
It's probably worth noting that I have ext2 and ext3 disabled. I have ext4 *enabled*, as the kernels' ext4 support is sufficient to mount ext2 and ext3 filesystems.
Kernel config forthcoming.

Including the emerge --info. Not that I think it will do terribly much good; I really don't know what kind of parameters or environment genkernel provides.
genkernel 3.4.24_p1 is using its own busybox which is 1.19.3 with patches (see in /var/cache/genkernel/src/) but unfortunately that version of busybox won't compile with kernel 3.4 headers because ext2_fs.h were moved
This doesn't happen with genkernel 3.4.35 but it is masked and require other masked dependencies like >=openrc-0.9.9
see also https://bugs.gentoo.org/show_bug.cgi?id=419511
as a workaround (but without patches), you can try comment #4 : https://bugs.gentoo.org/show_bug.cgi?id=419511#c4

genkernel output with BUSYBOX_VER=1.20.1
BUSYBOX_VER="1.20.1" genkernel --kernel-config=/root/kern_config --lvm --mdadm --disklabel all
genkernel --kernel-config=/root/kern_config --lvm --mdadm --disklabel all
give the same error and output.
You have to edit /etc/genkernel.conf and copy busybox 1.20 distfile to genkernel cache dir
Btw, patches included with genkernel's busybox won't be available, this could cause troubles if you need some special functionalities in initrd
Ah. I'd done the copy, but I hadn't noticed /etc/genkernel.conf. Trying again.
How do I look at the patch set applied to busybox, to see if it includes features I need?
As it turns out, it Works For Me.
I have been unable to compile a kernel with genkernel since at least gentoo-sources-3.4.0, and I'm running into the issue described here. I've tried editing my /etc/genkernel.conf accordingly and copying the corresponding busybox tarball to /var/cache/genkernel/src directory, but nothing seems to work, and I run into the problem mentioned here:
I need genkernel to work on this particular server. Any help would be appreciated.
This is the same as bug #419511 right?
I'll venture a guess this should be marked as a duplicate of bug #419511?
I'm closing this as a duplicate of bug #417261.
If using genkernel 3.4.36 is an option to you, that might help.
If you want/need to stick with stable genkernel, you will need to wait for 3.4.24_p2 to go stable (bug #425360).

Not sure if my issue is related to this, but I needed to patch lpfc_scsi.c according to this forum post:
Applying that patch allowed genkernel-3.4.38 to build and install a kernel from gentoo-sources-3.4.4. I'm willing to bet it resolved the issues I was seeing while attempting to build kernels > 3.3.5. Should I open a new bug report for this, because that patch would seem to be quite necessary now for genkernel users?
Definitely file a different bug; that's for a much newer version of genkernel than this bug's about, and it's about a different issue.
Let me clarify that my problem was with any version of genkernel that tried to build kernels from gentoo-sources newer than 3.3.5. My issue seems to be a bug in the kernel code, i.e. gentoo-sources, rather than genkernel. I'll file a separate bug report.
