Hi ,
I am woking on kernel-4.14 to give support for riscv (fu540 plateform) ,I am using glibc2.27 for my kernel after build the kernel when booting it at boot time it is giving me error "FATAL: kernel too old",
so please suggest me which glibc version I should use for my kernel-4.14 so that it will be compatible for riscv.
bellow is the error I am getting at boot time.
[ 1.106608] This architecture does not have kernel memory protection.
FATAL: kernel too old

Kernel support was added to mainline Linux in version 4.15, so that's
the baseline that glibc supports. You'll either have to use a mainline
kernel, or port glibc to the custom kernel.
Thanks,
Florian

The idea is also to remove these kernel checks for glibc 2.36 [1].

I want to port glibc for my custome kernel-4.14 for riscv64 but I want to get some Idea which files I need to change in glibc side so that I can start and try, please guide me.
Thanks

Now that master does not have the kernel check, you can just use the next
2.36 release or backport to the version you want. The commits are:
b46d250656794e63a2946c481fda29271342dd1a (Remove kernel version check)
c628c2296392ed3bf2cb8d8470668e64fe53389f (elf: Remove ldconfig kernel version check)
d2db60d8d830ef68c8d20a77ac3572d610aa40b1 (Remove dl-librecon.h header.)
Although you probably would only need b46d250656794e63a2946c481fda29271342dd1a.

Dear worker IT,
I wait again a good tutorial for glibc,
I need it for systemd 251,
Each time I read the documentation glibc I fall on to problems after,
Thanks you in advance for your answer (I use this system only the weekend),
Have a nice night from the France it is twenty three to four here,
Regards.
Dorian Rosse.
