scripts/unifdef.c:209: error: conflicting types for 'getline'

scripts/unifdef.c:209: error: conflicting types for 'getline'

[Justin Mattock]

Hello;
I am unable to compile the kernel
(just did a git pull a few minuets ago);
here is what I see:

WARNING: modpost: Found 1 section mismatch(es).
To see full details build your kernel with:
'make CONFIG_DEBUG_SECTION_MISMATCH=y'
  GEN     .version
  CHK     include/linux/compile.h
  UPD     include/linux/compile.h

make[2]: *** [scripts/unifdef] Error 1
make[1]: *** [__headers] Error 2
make: *** [vmlinux] Error 2

The only change to .config was:

SYSFS_DEPRECATED_V2 [=y]
to
SYSFS_DEPRECATED_V2 [=n]
to see if I can make udev from:

udev: starting version 137
[    7.557317] udev: deprecated sysfs layout; update the kernel or disable
CONFIG_SYSFS_DEPRECATED; some udev features will not work correctly

giving me this message.

also I did use a CFLAGS when compiling,
but never received this when doing so for:
2.6.29-rc5-00289-g460c133

any info would be appreciated.

regards;

What CFLAGS?  I can't reproduce the problem.

I also just loaded the latest libc
(not sure if this has anything to do);

I still can't reproduce the problem by using those CFLAGS/CXXFLAGS.

That probably updated /usr/include/stdio.h (?; I'm just guessing here).

could be.
also just to mention(not sure if it is relevant);
but when I compiled gcc(tired I was) I forgot to
set -arch flag(if this is correct option) so that gcc would
read:
/usr/bin/core2-pc-linux-gnu-gcc-4.4.0
instead of:
/usr/bin/i686-pc-linux-gnu-gcc-4.4.0

or however it would of been named when done.
I'll have to go back and redo that later on.

Perhaps getline() is now defined even without _GNU_SOURCE?  But I
doubt that...

Well, maybe I need to just do a
make clean
before compiling.

Well, that didn't seem to be a simple solution.
I guess I'm stuck with what I have.
