Hello everybody,

Did you configure? I often use this command, which starts with config of running kernel:

genkernel --menuconfig --install --integrated-initramfs --kernel-config=/proc/config.gz all

But I dont want to configure the kernel manually, I just wanna do genkernel. thats all.

that line is a fine start, if you don't want any manual steps skip `--menuconfig` part

bc was removed from the system set, but it's a dependency in at least the recent gentoo-sources.
Can you in fact get to a kernel building sitiuation without building bc?

I really dont understand, I mean I really followed every single step of the handbook and it is supposed to work. I am not doing anything different than the tutorials. Is is possible there is a bug of genkernel?

PC,

Your last genkernel compile reported success. Are you still having problems? If so, what are they?
ls -l /boot should show a new kernel, initrd/initramfs, and system.map made in the last few hours.
My conclusion is not that there is a bug in genkernel. Instead it appears that bc was removed from your system and portage thought it was still installed.

I thought that compilation takes hours it was just 5 minutes. the total time for the three commands

Google is your friend:

The kernel needs math lessons. ( :-)

did you run ls -l /boot? ls -l /boot should show a new kernel, initrd/initramfs, and system.map made in the last few hours.
did you try rebooting to the new kernel I think you made?

I see the kernel and other stuff under the /boot. I guess I need to search on it on my own little bit. (steep learning curve)

Thank you so much everybody for your kind answers though. I really appreciate.

Best wishes,

PC,

as I said I tried both different methods (perse`), both took less than 15 min even close to 10 min. However when I read the tutorials, handbooks etc., it is been told that it generally takes hours, that is why i deleted, everything and try to reload again. I am not sure that will solve the problem but again it just didnt make sense to me.

Thanks,

PC,

It sounds as if you now have a working kernel, probably built before your last build attempt.
Five minutes seems about right for a kernel rebuild with no, or minor, changes. If you want
to know how long a full kernel rebuild run "cd /usr/src/linux ; make clean" to remove all your
old kernel build, and then run genkernel again. The script I use is:

This nasty shit error happen when you have set-up CONFIG_INITRAMFS_SOURCE to some value && asking genkernel to pack initramfs to the kernel (aka making kernel selfbootable in UEFI mode)

In my case I had:
