 |
|
Hello, I have decided to build my own kernel through the handbook because using gentoo-kernel didn't work for some reason and when I try to run the "make install" command, it says:
| Code: | scripts/link-vmlinux.sh: line 50: 22655 Killed ${ld} ${ldflags} -o ${output} ${wl}--whole-archive ${objs} ${wl}--no-whole-archive ${wl}--start-group ${libs} ${wl}--end-group $@ ${ldlibs}
BTF .btf.vmlinux.bin.o
libbpf: failed to get EHDR from .tmp_vmlinux.btf
pahole: .tmp_vmlinux.btf: Invalid argument
LD .tmp_vmlinux.kallsyms1
.btf.vmlinux.bin.o: file not recognized: file format not recognized
make[2]: *** [scripts/Makefile.vmlinux:37: vmlinux] Error 1
make[1]: *** [/usr/src/linux-6.6.67-gentoo/Makefile:1171: vmlinux] Error 2
make: *** [Makefile:234: __sub-make] Error 2
|
I don't understand what I'm doing wrong since compiling the kernel went good for 3 hours up until the end where it errored out. |

Welcome to Gentoo Forums!
Which kernel?
| Code: |
sys-kernel/gentoo-sources
|
?
Did you run
| Code: |
make menuconfig
make
make modules_install
make install
|
?
Do you have sufficient ram?
Plz post
| Code: |
grep CONFIG_DEBUG_INFO_BTF /usr/src/linux/.config
|
If it is enabled ,try to disable it.

A three hour build seems very long to me, which suggests that the configuration enables a large number of unnecessary options or that the build system has very limited resources. Modern amd64 desktops can build even fairly featureful kernels in tens of minutes. Carefully tuned kernels on high end desktops can be done in a few minutes.
If I had to guess, I would start with alamahant's suggestion about available RAM. What is the output of free -h? |

I don't understand what you mean by which kernel, and yes I ran menuconfig and configured all the appropriate settings. This is the output when I ran the command:
| Code: | CONFIG_DEBUG_INFO_BTF=y
|
This is the output when I ran free -h:
| Code: | total used free shared buff/cache available
Mem: 5.8Gi 3.0Gi 2.1Gi 338Mi 1.3Gi 2.8Gi
Swap: 0B 0B 0B
|
What I meant when gentoo-kernel didn't work is that when I tried to reboot into Gentoo, it took me to a grub terminal. I tried to boot into Linux but nothing was in the /boot/ folder. |

Gentoo has many kernel packages
Plz run
and see some of them.
Since you are having a hard time booting I would suggest that
You properly install grub.
Then emerge
| Code: |
emerge -av sys-kernel/dracut sys-kernel/gentoo-kernel-bin
|
Update grub and reboot.
You will most likely be able to boot into your new system provided your fstab is correct.
Then having taken care of booting into your new system start playing with building your own kernel from scratch.
What do you mean by that

Have you mounted your boot partition?Is your boot partition defined in fstab?

Hello, I cannot boot into Gentoo without a kernel and like I said, gentoo-kernel doesn't seem work for me.

gentoo-kernel might not be working for you but gentoo-kernel-bin might.
It is precompiled and installed as a binary.You do not need to run make etc.

How do I use that kernel instead? |

First make sure you have installed grub properly(grub-install .........)
You do have an ESP partition correct?You have properly populated your fstab file no?
Then you simply run
| Code: |
echo "sys-kernel/gentoo-kernel-bin initramfs" >> /etc/portage/package.use/gentoo-kernel-bin
emerge -av dracut gentoo-kernel-bin
grub-mkconfigg -o /boot/grub/grub.cfg
reboot
|
If you can not install gentoo-kernel-bin because you have already installed gentoo-kernel, then simply uninstall first gentoo-kernel.
