FATAL: kernel too old

[naveen yadav]

Hi All,

I have made a cross compiler for ARM target.

On host i have fedore core -8. (Linux localhost.localdomain
2.6.23.1-42.fc8 ). I am using crosstool-NG script to Build this
toolchain.

I have used gcc 4.3.4,
binutils 1.91
glibc 2.8
kernel header 2.6.30


I have able to make cross tool and able to make executable.

when i run this program on my ARM target which is having kernel
2.6.30(compiled with tollchain from codesourcery 4.3.4) running i am
getting

"FATAL: kernel too old"

Can you pls suggest what is issue.

Best Regards
Naveen

This is glibc telling you that the kernel you're trying to use is too
old for that version of glibc.

I'm rather surprised this is happening, as the kernel version should have
been detected when you built glibc.

Does glibc correctly detect the kernel version when you cross-compile?

You can set the minimum supported kernel when you configure glibc with
the --enable-kernel option.
