Hi,

Yesterday i was trying to buildroot for my ARM920t and i think this is the bug.

Target: ARM920t
OS: Fedora 12 ( 2.6.31 using)
Kernel Headers: 2.6.32
Kernel used: 2.6.28

output/build/linux-2.6.28/scripts/unifdef.c

the getline() function in unidef.c contradicts with the already present getline
function in stdio.h and gives this error

error:
/usr/include/stdio.h:653: note: previous declaration of ?getline? was here

How i fixed the error?

i changed the getline function in unidef.c to get_line ie. other than getline
and it works fine.

That's a known problem in older versions of the Linux kernel when building on
new distributions. The official fix (which is included in 2.6.29+) is like you
describe (getline -> get_line).

Any reason why you want to use such an old kernel for a new project?

This is not a Buildroot bug, but rather a know bug when using old versions of
the kernel in newer distributions. I don't think there's anything Buildroot can
do to fix this.
