I'm trying to build a custom 2.4.18 kernel for my LFS distro b/ it won't compile for my i586 machine. I run the make mrproper && make menuconfig and get to the make dep and receive this message-->
gcc -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/mkdep scripts/mkdep.c
In file included from /usr/include/bits/posix1_lim.h:126,

make: *** [scripts/mkdep] Error 1

If you have any idea how to fix this problem please respond to this post.

Is it possible that you didn't call your kernel source directory "/usr/src/linux"? That can be a symlink -

$ ls -l /usr/src
total 12
lrwxrwxrwx 1 root root 12 May 18 18:17 linux -> linux-2.4.18
drwxr-xr-x 14 573 573 4096 Jun 26 23:34 linux-2.4.18

$ ls -l /usr/src/linux/include/linux/limits.h
-rw-r--r-- 1 573 573 765 Feb 25 14:38 /usr/src/linux/include/linux/limits.h

Hope it helps,
