kobject.h makes lilo compile break

kobject.h makes lilo compile break

[Simon Scheiwiller]

Hello

When I'm compiling lilo on a machine with kernel 2.5.54, I get the following
error:


gcc -c -O2 -Wall -g `( if [ -r $ROOT/etc/lilo.defines ]; then cat
$ROOT/etc/lilo.defines; else
echo -DBDATA -DBUILTIN -DDSECS=3 -DIGNORECASE -DLBA32 -DLVM -DEVMS -DM386 -D
ONE_SHOT -DPASS160 -DREISERFS -DREWRITE_TABLE -DSOLO_CHAIN -DVARSETUP -DVERS
ION -DUNIFY; fi ) | sed 's/-D/-DLFC_/g'` `[ -r /usr/include/asm/boot.h ] &&
echo -DHAS_BOOT_H` `cat mylilo.h` lilo.c

                 from common.h:20,
                 from lilo.c:25:

/usr/include/linux/kobject.h:24: confused by earlier errors, bailing out

As far as I got it, it's the kobject.h which causes the error as it includes
list.h which can't be included in userspace, but in the end the genhd.h
should work so can compile lilo.

Can someone help me how to solve that?

TIA
Cheers, Simon

Um, why not heed this warning?  :)

And yes, it looks like Pat got a change in to prevent kobject.h from
being included if __KERNEL__ is not set, but this is not the proper fix.
See the archives for the many discussions about not including kernel
header files in userspace programs.
